{{:Infobox:Radar}}
The radar triggers charting of the map of the force it belongs to.

It can be used to provide a small area of remote vision on the map; it also allows periodic scanning of distant chunks around it. The Radar has a high [[Electric system|power]] demand (300kW) so a radar indirectly contributes to [[pollution]] when powered by [[boiler]]s and [[Steam engine|steam engines]]. A radar can be continuously powered by eight solar panels and six accumulators. Seven solar panels and five accumulators is the most efficient; it gives the radar full power all but a short time in the morning, but never dips below the 20% power threshold for nearby scanning.

The radar will be attacked by enemies that come within very close range, like turrets, due to its status as a military building, but will not attract biters from long range like polluting structures do. The radar will show enemy lifeforms and structures, as well as [[Train|trains]], [[Car|cars]], and other [[player]]s in the scanned area.

== Nearby Pulse Scanning ==

The Radar continuously charts an area of 7×7 [[chunk]]s (224×224 [[Tile (unit)|tile]]s), centered on the chunk the radar occupies. This nearby area is updated as a single pulse approximately every second. At reduced power levels, this nearby pulse scan will take longer, which can lead to 'blinking' on the player's map similar to the long range scan. This is particularly noticeable at dawn and dusk on solar powered radar stations.

At 20% power the radar will pulse about every 4 seconds which will still keep the nearby area continuously lit on the map, but will provide reduced detail. 20% power can be achieved by a single [[solar panel]], or by using one isolating accumulator for every 5 radars.

== Long Range Survey Scanning ==

The Radar charts one distant [[chunk]] every time the sector scanning progress bar fills. This will take 33.333 seconds, if the Radar is receiving full power. Mouse-over or click-open the radar details to see this progress bar. Long range scanning is visible on the map as a single chunk lighting up for several seconds, then slowly darkening.

* It scans the unexplored chunks first, represented by the black areas on the map. Note that it also generates the chunks if they weren't generated at the time of the scan.
* One chunk scan takes 10 MJ of energy to complete. Since the Radar draws 300 kW of power, it takes 10 MJ ÷ 300 kW = 33.333 seconds to scan one chunk.
* This is done in an 29×29 chunks around the Radar, excluding the nearby 7×7 chunks.
** With a total number of 797 chunks (29×29 − 7×7), it takes one radar '''7 hours 20 minutes''' to complete one full scan cycle.
* If everything is already explored it continues to scan by re-scanning the longest-ago scanned chunk within range.
* Multiple radars will share long-range chunks, reducing the amount of time it takes to complete long-range survey scanning.
** This is a smart process, meaning that the radars will not scan chunks currently being scanned by other radars.

'''It is possible that a new alien nest will appear in a previously scanned chunk; just because you don't see it on the map, doesn't mean it is not there.

== Coverage ==

Radars grant sight of a square area around them, which is displayed brighter than the rest of the map. This allows the player to zoom into the normal world view from the map and makes interaction with [[blueprint]]s and [[deconstruction planner]]s possible.

[[File:Radar_coverage.png|thumb|500px|none|The coverage area of a radar and the player.]]

== Charting ==

If a [[chunk]] is '''scanned''' by a radar or player, the image of that chunk that is copied into the map of the players of this surface force (every force has its own map).

This procedure is called "charting".

=== Charting Process ===

If the contents of a chunk changes between two ticks, the content of that chunk is "charted" into the map. The map is just a bitmap, a picture. You can see the entities moving, you can see enemies walking. Every entity is represented by one or more pixels. Not every entity is drawn. Users can recognize what is drawn because of the color.

Charting of several chunks that change each tick might have an impact on game performance, manifesting in the form of lowered <abbr title="Updates Per Second">UPS</abbr> or <abbr title="Frames Per Second">FPS</abbr>.

=== Charting Decay Time / Fog of War ===

Once a scan for a chunk is triggered, it keeps actively charted for '''10 seconds'''. This effect can also be seen in the map of the chunk highlighted and dims within 10 seconds to a greyed out version of the chunk.

If charting is not repeated within the 10 seconds, the charting process stops for this chunk after 10 seconds and is not longer updated. What you see after that time is the last charted picture for that chunk (also called "fog of war").

=== Charting of Vehicles ===

Even in the fog of war you can see the last charted position of vehicles. Trains last positions are not charted, because they normally always move after the charting stops.

Vehicles are shown as a circle, with an arrow pointing in the direction that they're facing.

=== Invisible (black) parts of the Map ===

The [[World_generator#Generating_new_Chunks|World Generator]] creates a "border" of invisible chunks around each chunk, that becomes active at some time. Active chunks are those that become charted or those that are active because the pollution spreads onto them.

Damage

2019-03-06T15:24:04Z

LowBattery: /* Percentile resistance */ Fixed incorrect usage of the word "percentile", changed to "percentage" and "percent".

{{Languages}}
== Overview ==
In Factorio, entities have health, can die/be destroyed, and have resistances. ''Damage'' is defined as the concept of lowering an entity's health by using an attack, such as a gun firing at it, or a biter chewing on it. An entity's resistances will define exactly how much damage the entity will take off of an arbitrary attack.

The [[player|character]]'s maximum health is 250 (without [[energy shield]]s). Other entities' health values are listed in their individual entries.

== Achievements ==
The concept of damage is directly connected to the following achievements:
{{Achievement|run-forrest-run}}
{{Achievement|pyromaniac}}
{{Achievement|steamrolled}}
{{Achievement|golem}}
{{Achievement|watch-your-step}}

== Damage types ==

|}

=== Piercing power ===
Piercing power is present with [[Tank]] ammunition and piercing shotgun shells. It determines how many HP of enemies can a projectile damage before it is no longer able to travel further. To penetrate an enemy, the enemy has to be killed by the projectile, and the damage dealt for the kill must be less than current piercing power.[https://forums.factorio.com/viewtopic.php?f=5&t=30917] The damage dealt also decreases piercing power. For example, shooting medium biters with 75 health with a cannon shell of 300 piercing power means that the shell will pierce through 4 medium biters, killing them, and still destroy/damage one more target.

== Resistance ==
Resistance has two aspects:
=== Decrease, or "flat" resistance ===
Decrease resistance decreases the damage by specified number as long as the resulting damage wouldn't be less than 1. If the result damage would be less than 1, an alternate formula is used.
Let R denote the flat resistance value, D the incoming damage, and M the modified damage, after accounting for flat resistance. Then

if R+1<D

<code>M=D-R</code>

otherwise if D>1

<code>M=1/(R-D+2)</code>

otherwise

<code>M=1/(R+1)</code>.

If flat resistance matches or exceeds the raw damage, then modified damage is asymptotic towards 0, as shown by following example table:

{| class="wikitable"
|-
! Damage !! Flat Resistance !! Modified damage (with 0% resistance)
|-
| 5 || 0 || 5
|-
| 5 || 1 || 4
|-
| 5 || 2 || 3
|-
| 5 || 3 || 2
|-
| 5 || 4 || 1
|-
| 5 || 5 || 1/2
|-
| 5 || 6 || 1/3
|-
| 5 || 7 || 1/4
|-
| 5 || 8 || 1/5
|-
| ... || ... || ...
|}

=== Percentage resistance ===

Percenage resistance reduces the damage by the specified percent. It is applied ''after'' flat/decrease resistances when both are present and thus changes the 'modified damage' value above, decreasing it by the specified percentage. If the value is 100%, the entity is immune to the damage. This is the only way to have an entity immune to a type of damage, as flat reduction cannot reduce damage beneath 1.

As an example, an entity with 25% resistance to physical damage hit with a bullet dealing 100 physical damage would take 75 damage instead of 100.

The formula used for percentage resistance to damage is as follows:

Let M denote the flat-resistance-modified starter damage, and let P denote the percentage resistance (in decimal form, so 25%=0.25), and let F denote final damage.

<code>F = M * (1 - P)</code>

--------

In Factorio, resistances are displayed in the UI as follows:

Decrease resistance/Percentage resistance (Damage type)

So, an entity that displays 10/20% resistance to fire has 10 flat resistance and 20% percent resistance to fire. If the aforementioned entity were to take 30 fire damage, they would instead take 16 damage, after resistances were applied.

The formula used for the above:

16<sup>final damage</sup> = (30<sup>initial raw damage</sup> - 10<sup>flat resist</sup>) * 0.8<sup>20% resistance</sup>

== Combined formulas ==
Let D denote the raw incoming damage (of applicable type), R denoted the flat resistance value (against damage of the applicable type), P the percentage resistance (against damage of the same type) in decimal form (e.g. 20%=0.2), and let F denote the final damage (of applicable type) dealt to the target.
=== If R+1<D ===
F = (D - R) * (1 - P)
=== otherwise if D>1 ===
F = (1 - P) / (R-D+2)
=== otherwise ===
F = (1 - P) / (R+1)

{{Languages}}
{{:Infobox:Locomotive}}

The '''Locomotive''' is the engine for movement of [[Railway|trains]] over [[Railway#Tracks|track]]. Trains are useful for moving large amounts of items over large distances.

Locomotives are also good vehicles for the player to reach fixed destinations, as they are considerably faster than the [[car]] or [[tank]]. Naturally they do not have the same freedom of movement, however, as they are confined to the track. They can be set up to travel automatically between [[train stop]]s, or be controlled manually, even if the [[player]] is in a [[cargo wagon]] attached to the train, rather than the controlling locomotive itself. Automatic trains can also use [[rail signal]]s and [[rail chain signal]]s to designate different or changing paths on a railway, as well as manage multiple trains on multiple or intertwining tracks.

Locomotives are [[burner devices]] and require [[fuel]] to run; the more powerful the fuel used, the faster the locomotive's acceleration and top speed will be. [[Solid fuel]], [[rocket fuel]] and [[nuclear fuel]] will give +20%, +80% and +150% acceleration respectively, and provide +5%, +15% and +15% for top speed respectively. Multiple locomotives can be used on a single train to increase its speed.

While locomotives can be assembled by hand, the [[engine unit]] for it require [[Assembling machine|automated construction]] to build, so it cannot be built from raw materials by hand. The color of the locomotive can be customized.

== Connecting/Disconnecting a locomotive ==
To connect locomotives, cargo wagons or [[fluid wagon]]s to each other, either place the cars next to each other on the track (there will be an outlined green connection), or connect an already existing disconnected car by driving the locomotive near the car and press {{Keybinding|G}} by default. To disconnect the last car in a train, press {{Keybinding|V}} by default.

== Defense ==
Locomotives are a priority target of [[enemies]], so places where trains can stop should be [[Defense|defended]]. Locomotives in transit can usually crash through everything in its way (including biters, [[tank]]s, and the player), so defense in transit is less important. However, enemies can attack and destroy rails, potentially stopping the train. Biters won't often cause this, since automated trains will not move if they can't find a path to their destination - a broken rail interrupts their path.

[[Construction robot]]s are a good way to automatically repair damage at train stations.

== Maximum speed ==
The maximum speed that a locomotive can get to depends on the train that it is pulling. The speed of an accelerating train can be calculated with the following formula:

train_speed = (old_train_speed - (train_friction_force ÷ train_weight) + ((10 × number_of_locomotives_in_moving_direction × fuel_acceleration_bonus) ÷ train_weight)) × (1 - air_resistance_of_front_rolling_stock × 1000 ÷ train_weight)

where train_friction_force is <code>amount of wagons and locomotives ÷ 2</code> and train_weight is the summed up weight of each wagon and locomotive, see their individual pages for the weight values. The calculated train_speed is capped to <code>max_speed = 1.2 * fuel_top_speed_multiplier</code>.

* Fixed that some maps with modded selection-tool items failed to load.

== 0.16.8 ==
Date: 29. 12. 2017
=== Features ===

=== Minor Features ===
* Requester chests can now request stuff from buffer chests as was originally intended. Buffer chests are provided items only if all requester chests are satisfied for that specific item.

* More entities in high resolution: laboratory, radar, worker robots (construction and logistic), combat robots (defender, distractor and destroyer), combinators, electric & circuit wires, pumpjack, storage tank, player, solar panel, lamp, roboport, tank.
* All terrain now supports high resolution.
* Blueprint previews and ghost entities now have their walls, pipes and belts connected.
* New alert icons.
=== Balancing ===
* Removed Assembling machine 1 from the production science pack.
* Changed nuclear reactor stack size to 10.
* Moved cluster grenade recipe to military 4 research.
* Changed uranium ammo prerequisite from military 3 to military 4.
* Explosives now produce 2 per craft.
* Slightly adjusted some recipe craft times to better reflect their ingredient count.
* Changed the terrain building size limit to be based off the player reach.

* Resources scale slightly less over distance.
* No uranium as a starting resource also no uranium is ever generated near the starting area, you need to go look for it.
* There is 1.49 times more iron on the map to compensate for the extra iron required in a typical game.
=== Changes ===
* Disabled loading of saves before 0.13.0 version (You can use 0.13 to load older saves and re-save them).
* Train doesn't need to come to a full stop when manually changing train destination or switching from manual to automated mode.
* Removed the "shift" value from map generation settings as it wasn't needed anymore.

* It is possible to open/close and interact with the chat console when the map is being saved or server loosing connection dialog is active.
* The game uses only the cloud version of player-data and achievements on steam to avoid problems with resets.
* Increased the limit of recipe categories from 255 to 65535.
* New blueprint no longer includes entities marked for deconstruction.

* Added /server-save command that does the same thing as lua server_save, but doesn't disable achievements. ([https://forums.factorio.com/52414 more])
* Gamesave names in the load game dialog that are too long to fit the gui now show in a tooltip in full. ([https://forums.factorio.com/51653 more])
* Removed the option to turn off the item groups and sub groups from the GUi. It can still be done through the config file or lua commands.
* Added separate control option for placing tags on the map, so by default map scroll is left click, and place tag is right click.
* Allow easier dragging of underground pipes and belts when not moving in a perfect straight line.
* The Arithmetic Combinator can now use a constant as the first parameter, not only the second. So you can do operations like 2^SIGNAL. ([https://forums.factorio.com/51975 more])
* When building blueprints, any already existing building of the same entity type will have their settings updated instead of showing red. ([https://forums.factorio.com/51308 more])
* The options menu has been organized better. Some options were moved to a new "Interface" settings menu.

* Resources will have much less trees on them near the player starting area.
* Tanks no longer take miniscule amounts of damage from hitting trees.
* Previously, building while running at very high speed would create gaps. These are automatically filled now.
* Locomotive will show train ID in its tooltip. The ID can be used in circuit network conditions. ([https://forums.factorio.com/52003 more])
* When two trains are being merged, the decision which schedule should be used for the merged train has been changed from bigger schedule to schedule that has latest change. ([https://forums.factorio.com/54397 more])
* Number of entities in hand when previewing the entity to be built is now aligned to the entity.
* Added sliding when the player character collides with water or entities with rotated bounding box.
* Improved drawing of turret radii in blueprint. Many overlapping radii no longer covers terrain completely.
* External blueprint library is no longer merged with blueprint library in save. Instead, in-save library is always overwritten by the external one.

Water

LowBattery: Added information regarding the specific heat of water.

{{Languages}}
{{:Infobox:Water}}

'''Water''' is a [[fluid system|liquid]] which can be infinitely extracted from lakes and oceans using an [[offshore pump]]. After being pumped out and distributed via [[pipe]]s, water can be used to generate [[electric system|electricity]] by converting it to [[steam]] via [[boiler]]s or [[heat exchanger]]s. The specific heat of water is <code>200J / 1°C x unit</code>. It takes 200 joules to heat one unit of water by one degree Celsius.

[[File:Swimming-Fish.png|thumb|right|300px|A dark spot from which raw fish can be harvested.]]
'''Raw fish''' can be harvested from water. They can be used to refill a small amount of health instantly. In order to catch raw fish, look at a body of water and see if you see moving dark spots, then mine them the same way you would do with ore to get 5 fish per dark spot. To use the fish, just pick it up out of your inventory and eat it by clicking your left mouse button by default. Fish can be also collected via construction robots.

Using [[landfill|landfills]] on water where a fish is swimming will "destroy" the fish.

Tutorial:Nuclear power

2018-01-15T18:49:57Z

LowBattery: /* Simplest thing that works */

[[Nuclear power]] is a major new feature introduced in version 0.15. It requires higher level technology compared to either solar power or steam boiler power, but it offers very high power output in exchange. It's a great solution for middle- to end-game power generation and it works well in combination with other power generation techniques.

This guide is written for people who want to know exactly how nuclear power works, but don't necessarily want all the solutions. It focuses on what you should do and what you should know to get Nuclear up and running, but doesn't tell you what to do or exactly how to solve the problems.

== First steps ==

:'''Technology required:''' [[Nuclear power (research)|Nuclear power]]
:''You can mine uranium ore sooner, but you'll need the nuclear power technology to do anything useful with it.''

=== [[Uranium ore]] ===
To start, you'll need uranium ore. It glows green, so you can't miss it. It tends to form smaller deposits, though, and you may have to search a while to find a good patch.

Like every other ore in the game, you can mine it with an [[electric mining drill|Electric mining drill]]. Unlike every other ore, however, only the [[electric mining drill| Electric mining drill]] will do. You also need to supply [[sulfuric acid]] to the drill. The drills conduct excess acid through themselves, so a row of drills can be supplied by acid from a single side.

:'''Mixed ores:''' If a mining drill covers even a single patch of uranium ore, it will require acid to run at all. The mine will produce mixed ore, as usual.

=== [[Uranium processing|Ore processing]] ===
Once you've got raw uranium ore, you'll need to process it into [[uranium-235]] and [[uranium-238]]. You do this in a centrifuge.

In an un-moduled [[centrifuge]], you can process one ore every 13.3 seconds.

Centrifuges produce a combination of U-235 (the light green stuff) and U-238 (the dark green stuff). Every ten ore processed have a chance to become precisely one of these two products. Out of every 1k ore you process, you can expect to get, on average:

{| class="wikitable" |-
! Count !! Product
|-
| 7 || U-235
|-
| 993 || U-238
|}

That means you can roughly expect to get a single U-235 in one out of every 143 ore. A centrifuge can then be expected to produce U-235 every 1904 seconds. Later on, this won't matter so much. However, when you first start out, this will be an important bottleneck.

:'''Regarding averages:''' Be aware, random is random. These values are ''average'' values. Which means that over the long term, they work out to about these figures. In reality, you'll see long stretches with no U-235 and short stretches with lots of them. Eventually, it won't matter much. But early on, make sure your generation rate is sufficiently high, or you have a sufficient reserve, so you don't find yourself without power when you hit an unlucky stretch.

=== Fuel ===
Before you can burn it in a nuclear reactor, you need to create [[uranium fuel cell]]s. You'll probably be using an assembling machine 2, so these will take 13.3 seconds to create as well. Which is fine because fuel cell creation will very rarely be the bottleneck.

You won't want to automatically convert all U-235 into fuel. Only convert what you need to fill your reactor. You're going to want a big fat stockpile of it when you research [[Kovarex enrichment process|kovarex enrichment]] later on.

Fuel cells are produced in stacks of 10, and to produce one such stack you need 1 U-235, 19 U-238, and 10 iron plate.

:'''Tip:''' It isn't a bad idea to use a chest and just stick a pile of iron in it rather than belting the iron in. A full chest of iron probably won't run out before you get bots and replace it with a requester.

Each fuel cell has a nominal energy value of 8 GJ, but it's possible to make them go even farther with reactor neighbor bonuses (more on that later).

=== [[Nuclear reactor]] ===
Once you've got fuel, you'll need to burn it in a nuclear reactor. This is the first step toward turning it into usable energy.

A reactor will produce exactly 40 MW of heat energy. Since a Watt is a Joule per second, this means the reactor will consume one fuel cell every 200 seconds.

Once expended, reactors will produce a "[[used up uranium fuel cell]]", which will need to be cleared. Initially, these will simply accumulate in a chest. Eventually, you can reprocess them into U-238.

:'''Working backward:''' A reactor consumes a fuel cell every 200 seconds and each U-235 gives 10 fuel cells, so every U-235 provides 2000 seconds of reactor power. A centrifuge requires about 1904 seconds to produce a U-235, so you'll need about one processing centrifuges per reactor.

The reactor needs input of fuel and produces heat that needs to be exported using [[heat pipe]]s that go to a [[heat exchanger]] (unless a [[heat exchanger]] is attached to the reactor).

=== [[Heat exchanger]] ===
The heat exchanger takes heat and uses it to convert [[water]] into [[steam]]. It works much like the boiler, but instead of burning fuel, you need to connect it to a heat source. The heat input is marked by a flame when you're placing it.

For simple reactor designs, you can connect it directly to your reactor (which produces heat at points also marked with a flame).

Heat exchangers also require water input, in precisely the way boilers do. They can heat up to 103.09 units/second of water into 500°C steam.

Heat exchangers produce nothing when they are below 500°C. Since they only cool as a consequence of heating water, they will never cool to below that temperature once they've reached it.

Heat exchangers transfer 10 MW of power, so you'll need 4 exchangers to fully consume the power produced by a lone reactor. (Neighbor bonuses can increase this significantly. Again, discussed later.)

The [[steam]] can then be transported to the [[Steam turbine]] using normal [[Pipe]]s

==== [[Heat pipe]]s ====
More complex designs will require heat pipes. Heat pipes work much like regular pipes. Like regular pipes, they have limited throughput, which means that shorter pipes are better.

Connect heat pipes point to point, flame to flame, exactly as you would with water pipes. Heat pipes cannot go underground, so if water pipes need to cross them, the water pipe will need to go under. They don't block movement, though, so you can walk right over them.

Throughput on heat pipes is far more limited than regular pipes, in part because there is no analogous "Heat pump". Here are some rough limits on transfer distance:

{| class="wikitable" |-
! Power !! Distance
|-
| 40 MW || ~140
|-
| 80 MW || ~80
|-
| 120 MW || ~55
|-
| 160 MW || ~45
|}

Past these distances, less than 100% of the power will be transferred. This is because at this distance, the maximum reactor temperature of 1000ºC is insufficient to heat the pipe to beyond 500ºC.

:'''Heat pipe storage:''' Heat pipes can store quite a bit of heat as well. A single heat pipe can hold as much energy as a tank with 5.1k steam in it, which makes them even more space efficient than tanks for holding energy (though considerably more expensive). Be cautious, however, with transfer efficiencies. It's very easy to lose more power than you store with an inefficient design.

=== [[Steam turbine]] ===
These are the steam engine's beefy big brother. Using regular fluid pipes, you'll pipe the steam produced by heat exchangers into these turbines.

:'''Perfect matches:''' The steam turbine is a perfect match for the heat exchanger. The steam engine is a perfect match for the boiler. Although it is possible to get energy out of mismatched systems, it's very wasteful and there's no real reason to do it.

Steam turbines consume up to 60 units of steam/second, so you need roughly two steam turbines for every heat exchanger. At large scales, however, you can use fewer turbines, since exchangers only produce 103.09 steam/second. You'll require a separate pump for every 20 turbines.

=== Simplest thing that works ===
At this point, you have all the parts to build your very first reactor:

* A few uranium miners, supplied with sulfuric acid
* 1 Centrifuge, processing uranium ore
* 1 Assembling machine, making uranium fuel cells
* 1 Nuclear reactor
* 4 Heat exchangers, supplied by a single off-shore pump
* 8 Steam turbines

And, of course, assorted belts, inserters, filter inserters, and other tools for moving things around. This will produce a maximum of 40 MW of power.

== Moving forward ==
Past your simplest reactor, there are some additional nuclear features of which you should be aware.

=== Neighbor bonus ===
This is a critical part of how nuclear designs scale, but it's not complicated. Simply put:

'''Every reactor gets +100% heating power for every active neighboring reactor.'''

Neighbors have to align completely on each side, so reactors will line up in a nice square grid. When they do, the neighbor bonus is activated. You can see the current bonus by hovering over an active reactor.

The bonus to heating power does not increase the fuel consumption. Rather, it simply increases the heat produced!

This, of course, means you'll need more heat exchangers and steam turbines to turn that heat into electricity.

{| class="wikitable" |-
! Configuration !! Reactors !! Exchangers !! Turbines !! Power !! Power per reactor
|-
| Single || 1 || 4 || 7 || 40MW || 40MW
|-
| 2x1 || 2 || 16 || 28 || 160MW || 80MW
|-
| 2x2 || 4 || 48 || 83 || 480MW || 120MW
|-
| 2x3 || 6 || 80 || 138 || 800MW || 133MW
|}

'''How to count heat exchangers:''' Count the number of edges where reactors fully touch. Double that. Add the total number of reactors. Then multiply it all by 4. That's your count of Heat Exchangers. You'll need 1.718 turbines per exchanger (rounded up). Each exchanger will provide up to 10 MW of power.

=== Always on! ===
Unlike every other power generation technique, nuclear reactors '''DO NOT''' scale down power usage. Nuclear reactors will continue consuming one fuel cell every 200 seconds, regardless of the need.

As the reactor consumes its fuel, it heats up to a maximum temperature of 1000°C. At that point, additional fuel burned is simply wasted.

Turbines do scale their production (and steam consumption) to match demand. Likewise, exchangers won't consume heat if there's nowhere to put the steam.

:'''Turbines and engines:''' Be aware that steam turbines and steam engines are both the same "class" of energy producer, so they'll need to be scaled all together. This means that in a complete energy system, your coal boilers may be running when the nuclear plant could fully cover the load. And, worse yet, the nuclear power is just being wasted!
:Consider using accumulators, switches, and circuit logic to disable the coal boilers when nuclear systems can cover the demand.

The simplest solution to this problem is to just run the nuclear reactors part of the time. You can store steam in tanks. (And check out the "fill gauge"; the steam floats!) Since exchanges produce 120 steam/second and a tank holds 25k steam, a tank will keep 208 seconds worth of heat exchanger.

You can put a tank or two at the end of each heat exchanger and use circuit logic to only insert a fuel into the reactors when they get low. Make sure all exchangers are powered at the same time, or you won't get full neighbor bonuses. If you can't keep it from over-fueling, you can also add extra tanks to lengthen the cycle.

=== Enrichment ===
:'''Required technology:''' [[Kovarex enrichment process (research)|Kovarex enrichment process]]
:''Kovarex Enrichment allows you to turn some U-238 into U-235, but it's slow and takes a lot of U-235 as catalyst.''

Your first few patches of uranium ore will last you a reasonable length of time, but eventually you will start running out of ore and places to put extraneous U-238. Enrichment helps solve both problems.

The enrichment process takes about 67 seconds in an un-moduled centrifuge. It requires 40 U-235 (!) and 5 U-238 and makes 41 U-235 and 2 U-238. In effect, it turns 3 U-238 and turns it into 1 U-235; it just requires an extra 40 U-235 and 2 U-238 along for the ride to act as a catalyst.

:'''All the things!:''' Before you ''enrich all the things!'', be aware that you do need 19 U-238 for each fuel cell, as well as requiring it for uranium ammo you will want for storing inside biters and their nests. Circuit logic can help you put a limiter on large-scale enrichment operations.

One Centrifuge enriching uranium is sufficient to supply 29 reactors with fuel, assuming plenty of U-238.

=== Reprocessing fuel ===
:'''Required technology:''' [[Nuclear fuel reprocessing (research)|Nuclear fuel reprocessing]]
:''Reprocessing turns your spent fuel into U-238.''

Eventually, you will run out of places to put spent fuel. You can use reprocessing to turn it back into U-238 to use for enrichment, fuel cells, or ammo. Of the 19 U-238 that go into each 10-pack of fuel cells, this returns 6. This significantly reduces the total ore requirement for nuclear fuel.

=== Weapons ===
:'''Required technology:''' [[Uranium ammo (research)|Uranium ammo]] / [[Atomic bomb (research)|Atomic bomb]]
:''Better bullets / Bigger bombs''

With the Nuclear Age comes nuclear weapons. Uranium ammunition is top-tier, especially when you load a tank with it. It mows down biter nests and clears swarms quite quickly. It uses U-238, so you've probably got plenty of it lying around.

On the other side, you can get [[atomic bomb]]s, which are rockets (shot by a [[rocket launcher]]) that do incredible damage. Be aware, they can easily kill you if you fire them anywhere near you, and even at max range, it's advised that you run in the opposite direction. Rather than a single explosion, they do damage in an expanding ring, giving you time to escape. They require a lot of U-235 and blue chips, so they're an expensive weapon.

Tutorial:Nuclear power

2018-01-15T18:43:49Z

LowBattery: /* Ore processing */

[[Nuclear power]] is a major new feature introduced in version 0.15. It requires higher level technology compared to either solar power or steam boiler power, but it offers very high power output in exchange. It's a great solution for middle- to end-game power generation and it works well in combination with other power generation techniques.

This guide is written for people who want to know exactly how nuclear power works, but don't necessarily want all the solutions. It focuses on what you should do and what you should know to get Nuclear up and running, but doesn't tell you what to do or exactly how to solve the problems.

== First steps ==

:'''Technology required:''' [[Nuclear power (research)|Nuclear power]]
:''You can mine uranium ore sooner, but you'll need the nuclear power technology to do anything useful with it.''

=== [[Uranium ore]] ===
To start, you'll need uranium ore. It glows green, so you can't miss it. It tends to form smaller deposits, though, and you may have to search a while to find a good patch.

Like every other ore in the game, you can mine it with an [[electric mining drill|Electric mining drill]]. Unlike every other ore, however, only the [[electric mining drill| Electric mining drill]] will do. You also need to supply [[sulfuric acid]] to the drill. The drills conduct excess acid through themselves, so a row of drills can be supplied by acid from a single side.

:'''Mixed ores:''' If a mining drill covers even a single patch of uranium ore, it will require acid to run at all. The mine will produce mixed ore, as usual.

=== [[Uranium processing|Ore processing]] ===
Once you've got raw uranium ore, you'll need to process it into [[uranium-235]] and [[uranium-238]]. You do this in a centrifuge.

In an un-moduled [[centrifuge]], you can process one ore every 13.3 seconds.

Centrifuges produce a combination of U-235 (the light green stuff) and U-238 (the dark green stuff). Every ten ore processed have a chance to become precisely one of these two products. Out of every 1k ore you process, you can expect to get, on average:

{| class="wikitable" |-
! Count !! Product
|-
| 7 || U-235
|-
| 993 || U-238
|}

That means you can roughly expect to get a single U-235 in one out of every 143 ore. A centrifuge can then be expected to produce U-235 every 1904 seconds. Later on, this won't matter so much. However, when you first start out, this will be an important bottleneck.

:'''Regarding averages:''' Be aware, random is random. These values are ''average'' values. Which means that over the long term, they work out to about these figures. In reality, you'll see long stretches with no U-235 and short stretches with lots of them. Eventually, it won't matter much. But early on, make sure your generation rate is sufficiently high, or you have a sufficient reserve, so you don't find yourself without power when you hit an unlucky stretch.

Tutorial:Circuit network cookbook

2017-09-06T16:44:54Z

LowBattery: /* Conditional splitter */

{{Languages}}
== Foreword ==

This page provides examples of simple circuit network designs and some not so simple designs that others can use, combine and modify. They are designed to be as easy to understand as possible. To see the settings of combinators without opening them, the option "Show combinator settings when detailed info is on" in the graphics options has to be checked and detailed info has to be turned on.

==Lamp showing chest content condition==
[[File:LightWiredToChest.png|right|218 × 412px]]

This is the simplest possible use of circuit-network. A lamp is light depending on the number of goods (in this example empty barrels) in a chest.

===Setting up circuit connection===
* The lamp is connected to the chest
* the lamp is set to light if the chest contain less than 10 empty barrels.
{{clear}}

[[File:LamponBarrelCondition.png|right|400x400px]]
===To set the light condition===
# open the lamp (right click on it)
# Set the input to barrels
# Set the operator to < (less than)
# Set the constant number:
## Right click on the constant number
## Move the slider until 10 is shown, or edit the value box directly
## Press set

Depending on the condition you set, the lamp may light if the chest is empty, or if it contains the required quantity of items.

The drawback with this scenario is that the lamp has a white light , and is therefore difficult to differentiate from an ordinary lamp at night.

== Oil Setups ==
[[File:LgtOilCracking.png|left|400x400px]]
=== Light Oil Cracking ===
* This circuit provides balanced light oil and petroleum gas production by cracking excess light oil into gas.
* The [[Pump]] is connected to the [[Storage tank]] by a [[Red wire]].
* The [[small pump]] has an enabled condition set to '''Light Oil > 2000'''.
{{clear}}

[[File:HvyOilCracking.png|left|400x400px]]

=== Heavy Oil Cracking ===
* This circuit extends on the previous circuit by adding optional heavy oil cracking to provide lubricant etc.
* The [[Pump]] has an enabled condition set to '''Heavy oil > 2000'''.
{{clear}}

[[file:BalancedPlasticSulfur.png|left|400x400px]]

=== Petroleum split evenly between plastic and sulphuric acid ===
* This circuit buffers gas in the tank until there is at least 100, then it lets the tank drain until there is less than 50 and the cycle repeats.
* It has a few elements that work together to do achieve this.
* Firstly the [[Pump]] is connected to the [[Wooden chest]] by a [[Red wire]] and the enabled condition on the [[Pump]] is set to '''Raw wood > 0'''.
* Both of the [[Inserter]]s are connected to the [[Storage tank]] by [[Red wire]]s.
* The enabled condition on the left inserter is '''Petroleum gas > 100'''
* The enabled condition on the right inserter is '''Petroleum gas < 50'''.
* You will need to insert a single "Raw wood" into the chest to make it all work.
<br />
* It is also possible to do this with [[decider combinator]]s instead of the inserters, belt and the Wood chest or even just belts.
{{clear}}

== Lights ==
[[File:ConditionalLights.png|left|400x400px]]
=== Conditional Lights ===
* In this circuit we connect a series of [[lamp]]s to a [[Storage tank]].
* By setting different conditions on each [[lamp]] we can build an indicator strip.
* The Enabled condition of the first [[lamp]] is '''Petroleum gas > 100'''.
* The others light up when gas is greater than 200, 300, 400 and 500 respectively.
{{clear}}

In this scenario you can connect the storage tank to the lamps directly.

[[File:ColoredLights.png|left|400x400px]]

=== Colored Lights ===
* To light a [[lamp]] with a color rather than white, you need an intermediate device like an [[Arithmetic combinator]] that can send a color signal.
Instead of directly connect the the [[Lamp]] and the [[Storage tank]] you need:<BR>
1 Add the [[Arithmetic combinator]].<BR>
2 Connect the [[Storage tank]] with the input of the [[Arithmetic combinator]].<BR>

[[file:MulitipleChestsAndPoles.png|left|400x400px]]
=== Multiple Storages ===
* If you connect multiple chests to a pole, the pole displays the sum of items in all the chests.
* This also works with [[Storage tank]]s and [[roboport]]s.
{{clear}}

[[File:ConstantComb.png|left|400x400px]]

=== Constant combinator ===
* With a [[constant combinator]] you can generate any signals you may need.
* In this example we have generated a signal of 50 Laser turrets and 200 Piercing round magazine.
* Constant combinators are not of much use on their own but we shall use them later.
{{clear}}

[[File:LogicGates.png|left|400x400px]]

=== Logic gates ===
* In each case the two inputs can be connected with the same color wire or different colors. The inputs are powered by two [[Constant combinator]]s each of them output an A signal with value 1 for true and nothing or false.
* You can use [[Decider combinator]]s to make all of the common logic gates.
* The output for each should be set to 1 and the signal of your choice.
* Use the following settings to create different gates:
{{clear}}

NOT A=0
NOR A=0
NAND A<2
XOR A=1
AND A=2
OR A>0

{{clear}}

[[File:ThisASign.png|left|400x400px]]

=== Constant combinator signs ===
* You can use [[Constant combinator]]s to make signs, just set the letter signals in the combinator, each combinator can display 2 characters side by side.
{{clear}}

[[File:MemoryCell.png|left|400x400px]]

=== Memory Cell / Counter ===
* Basic memory cell that counts all the items moved by the inserter
* The [[Fast inserter]] is connected to '''BOTH''' ends of the arithmetic combinator.

* If the [[Fast inserter]] hasn't picked anything up this tick the input to the Arithmetic combinator is the same as and output and hence the values are persisted.
* When the [[Fast inserter]] does pick something up its value is added to the output from the previous tick thus incrementing that item.
{{clear}}

[[File:BeltCache.png|left|400x400px]]

=== Automatic Belt-Cache ===
* Some intermediate products are huge in demand during peak-production only. To bypass the need of providing a huge amount of factories in order to cover that peaks, a cache-unit can be used. The unit stores items, while the belt has backed up (so theres obviously no current demand downstream) and releases items as soon as the belt gets too empty.
* The blue area are 3 parts of Express belts. According to the wiki, each belt can hold up to 7.11 items. This means the feeding fast belt can not provide 7.11 items for the express belts as long as the belt is moving. (And while the belt is moving, we don't want to cache items, but let regular production run, or even release items from the cache.)
* This means, once the counters on the two express belts are 7.11 each, the belt has backed up, so we can start "caching" items into our storage array.
* For this purpose, the counters are connected to the arithmetic combinator (A) which multiples the input (*100) into green signals. So, if the belt has backed up, B shows ">1422" green signals.
* This is the activation condition for the Belt (C), which will redirect the input tp the storage array.
* Since items should only be released if the belt starts to clear, the counter (D) is evaluated by the belt (E) which is only activated, if item-count on (D) is smaller than 6 (this number has to be adjusted to personal needs, when the cache should become "active" and release items)
* The layout can be extended to cache whatever amount of items is required. (Some balancing for the release-method would be required ofc.)
{{clear}}

[[File:combinatorMultiplierDetailed.png|left|400x400px]]
=== Multiplier and Dictionaries/Arrays ===
* Multiplying two signals together is simple and requires only a single combinator, however multiplying a set of signals is more complicated.
* A proof is shown below for the equation and why it works.
* A dictionary is a system that allows a value on a specific signal to be accessed. For example, A can contain many signals (either from a constant combinator or memory cell) and B can contain 1 of a specific signal (such as blue signal). What remains is the blue-signal value from A. This is because all the other signals are multiplied by 0.
* Arrays are similar to dictionaries, but instead of using a signal as a key, we use a number. Constant combinators are placed mapping each signal to a unique number (such as 1 yellow belt, 2 red belt, 3 blue belt, 4 burner inserter, etc). Then, use a combinator of "each = index OUTPUT 1 of each" and plug that in as the input to a dictionary.
[[File:combinatorMultiplierMath.png|left|400x400px]]

((A+B)^2 - (A-B)^2)/4 = AB
(A+B)^2 - (A-B)^2 = 4AB
(A^2 + 2AB + B^2) - (A^2 - 2AB + B^2) = 4AB
4AB = 4AB

{{clear}}

== Inserters ==
[[File:LimitItemsPlacedIntoAChest.png|left|400x400px]]
=== Limit items placed into a chest ===
* The [[Inserter]] is connected to the [[Wooden chest]] using a [[Red wire]].
* The inserter's enabled condition is '''Advanced Circuit < 10'''.
* In reality this means the inserter may place more than 10 Advanced circuits in the chest because it could pick up-to 3 at once.
* This effect can be even greater with Stack inserters because of their large carrying capacity.
* This technique still gives far greater control than limiting the inventory on the chest.
{{clear}}
=== Balanced chest insert ===
Goal: Load n chests with approximately the same number of items.
* Place n chests and n inserters.
* Place 1 [[Arithmetic combinator]]
* Set the combinator to take Each (yellow star) and divide by the negative number of chests. ie -n.
* Connect all chests to each other and to the input of the combinator using red wire.
* Connect all inserters to each other and to the output of the combinator using red wire.
* Connect each inserter to the box it inserts into with green wire.
* Set the enable condition on each inserter to be Everything (red star) < 0.

The combinator calculates the average number of items in the chests, and makes it negative. Each inserter gets the amount in the chest it is inserting to and adds the negative average, ie it calculates how many more than the average it has in its chest. Thus if that number is negative, it has less than the average in the chest and it enables.

Due to inserter stack bonus the count is not exact. If precise count is needed, set the inserter stack size to 1.

{{clear}}

[[File:SmartOutpostUnloader.png|left|400x400px]]
=== Keeping outpost stocked with specified items ===
* This circuit keeps a [[Storage chest]] at an outpost stocked with customized levels of different items.
* For example you could keep an outpost stocked with 50 laser turrets and 200 piercing magazine rounds but not have to worry about it being over filled.
* The [[storage chest]] is attached to the input of the [[Arithmetic combinator]] (left side in the picture) with a [[Red wire]].
* Another couple of [[Red wire]]s join the output of the [[Arithmetic combinator]] (right side) to the [[constant combinator]] and to the [[stack filter inserter]].
* The [[Arithmetic combinator]] '''multiples''' each input value (from the storage chest) by '''-1'''.
* Finally the filter stack inserter's mode of operation is set to '''Set filters'''.
<br />
* So the input to the [[stack filter inserter]] is '''<Constant combinator> - <Storage chest contents>''' and the filter is set to filter the item of greatest demand.
{{clear}}

[[File:SolarAccumalatorBalancer.png|left|400x400px]]

=== Balanced Solar panel / Accumulator Production ===
* This circuit balances production of [[Solar panel]]s and [[Accumulator]]s to a desired ratio in my case 24:20.
* The first [[Arithmetic combinator]] takes the number of accumulators in the chest and '''multiples''' it by '''24'''.
* The second [[Arithmetic combinator]] takes the output of the first combinator and '''divides''' it by '''20'''.
* This gives us the number of accumulators that we can directly compare to the number of Solar panels in both inserters.
* If the number of accumulators is greater we enable the Solar panels inserter, if the number of Solar panels is greater we enable the accumulators inserter.
* However, if they are equal, neither machine does anything. So we add a single accumulator to one of the inserters using a constant combinator and a wire of the other color, therefore breaking the deadlock.
{{clear}}

== Sushi Belts ==
[[File:SushiScience1.png|left|400x400px]]
=== Reading Belt Design ===
* Six belts in a row are connected with Red wire and set to '''Read belts contents''' and '''Hold'''
* This [[Red wire]] is then connected to the inserters that insert onto the belt.
* Read hand contents is unselected for all inserters.
* Mode of operation is set to '''Enable/Disable''' on all inserters.
* The first inserter is enabled when '''Science pack 1 = 0'''
* The other inserters are set similarly for the other science packs.
{{clear}}

[[File:SushiScience2.png|left|400x400px]]
=== Memory Cell Design ===
* This circuit counts the number of items of each type on a looping belt by counting the numbers that are added and removed from the belt by inserters.
* Each inserter that takes items off the belt is connected together with Red wire and each of these inserters is set to '''Mode of operation none, Read hand content selected''' and '''Hand read mode pulse'''.
* These inserters are connected to the input of the left arithmetic combinator.
* The left [[Arithmetic combinator]] multiples '''each''' input by '''-1''' and outputs it to '''each'''.
* The right [[Arithmetic combinator]] is a '''memory cell''' as above.
* The memory cell's input is connected to the inserters that are placing items on the belt and the output of the left [[Arithmetic combinator]].
* The inserters that place items onto the belt have an enabled condition that is based on the number of items on the belt.
{{clear}}

== Splitters ==
[[file:CondSplitter.png|left|400x400px]]
=== Conditional splitter ===
* This is the simplest circuit you can have for "controlling" a splitter.
* A signal X=1 is transmitted from off screen when the items need to be sent down the belt.
* The belt on the left is enabled when X=1.
* The belt on the right is enabled when X=0.
* The two belts are wired together and to a pole.
{{clear}}

[[File:PrioritySplitter.png|left|400x400px]]

=== Priority Splitter ===
* This circuit prioritizes items to the belt going of the screen to the left but will send items straight on if the belt to the left is backed up.
* Its not perfect and will leak some items but its good enough for most applications.
* The balancer means it will work even if the supply or demand is uneven.
<br />
* It is critical that the belts are setup as in this picture otherwise it may not work.
{{clear}}

== Power ==
[[File:SteamBackup.png|left|400x400px]]
=== Backup steam power ===
* The [[steam engine]]s are not directly connected to the power network. They are connected to the power network through a [[Power switch]].
* The [[power switch]] is connected to one of the [[accumulator]]s in the main network.
* The [[power switch]] turns on when A < 10. That is when the [[accumulator]]s are less than 10% full.
{{clear}}
=== Optimal usage of fuel for nuclear power ===
Unlike the normal steam power that adjusts fuel usage based on power usage, the [[Power_production#Nuclear_power|nuclear reactors]] spend fuel in fixed units of time. To be exact, the consumption of 1 fuel cell takes exactly 200 seconds.

Combined with the fact that creating the nuclear fuel cells are time consuming and expensive to create, it is therefore beneficial to optimize their use to match the actual consumed power.

[[File:NuclearSetupWithCircuits.png]]

The above picture shows a setup with 4 reactors, that spend only 1 fuel cell each whenever steam backup runs low.

There are a couple of elements in this setup:

* 4 Storage tanks are connected with a wire, that is then connected to the substation. Each storage tank can contain 25.000 units of steam, for a total of 100.000 units. It is not necessary to connect more than 4 tanks, even though more tanks are added in the setup. However, connecting fewer is not recommended, since a single tank may fluctuate too much to give steady readings.
* 1 [[Tutorial:Circuit-network_Cookbook#SR_latch|SR-latch]], these are the 2 top-most combinators and the one on the right side. The low mark is set to 1.500 (1.5% of connected storage tank capacity) and the high mark to 5.000 (5% of connected storage tank capacity). The output can be anything except [[Used_up_uranium_fuel_cell|Empty fuel cell]]. In this example we output L (Made an error in the image, the trigger condition is of course L > H, not L < H). The inputs of the latch is connected to the substation, and so is the output.
This will trigger the response necessary during normal operation when we have enough fuel and have already started the reactors. The reason that we can have such low lower bound is that after start-up of the reactors the temperature will never drop below 500C, and thus immediately after a new fuel cell has been input the heat exchangers will start to generate more steam. The reason for the high mark to also be quite low is that we don't want it to trigger the insertion of another fuel cell until the previous one has been spent.
* 1 stand-alone combinator (The one on the left), which checks if amount of steam is < 200 (0.2% of connected storage tank capacity), and outputs 1 [[Used_up_uranium_fuel_cell|Empty fuel cell]]. The inputs of the combinator is connected to the substation, and so is the output.
This will trigger the response necessary during start up, and after running out of fuel.
* Output inserters that take [[Used_up_uranium_fuel_cell|Empty fuel cell]] from the reactor. This is connected to the substation (or any adjacent element that is then connected to the substation) and listens for the output of the SR-latch, ie. L > 0. Furthermore, it is setup to "read hand content" in "hold mode".
* Input inserters that put fuel into the reactor. This is connected to the substation (or any adjacent element that is then connected to the substation) and listens for the output of the output inserters OR the stand-alone combinator, ie. [[Used_up_uranium_fuel_cell|Empty fuel cell]] > 0. The "override input stack" is set to 1, so that it only inserts 1 fuel cell at a time.
This means that whenever the low mark is triggered, the output inserters will grab the empty fuel cell in the reactor, this then triggers the input inserters to insert a new cell. This only works if there IS an empty cell in the reactor, therefore the need for the stand-alone combinator to force always on of the input inserters, whenever the system previously ran out of the fuel, or is in start-up mode.
* 1 constant combinator to output whichever color you want the lights to be. This is not necessary at all, but looks nice.
* Lots of lamps to make it look nice, optionally setup to only turn on whenever steam level is at a given level to see storage.

== Latches ==
=== SR latch - single decider version ===
[https://forums.factorio.com/viewtopic.php?f=193&t=14556 This discussion] on the Factorio forums starts with the common 2 decider RS latch version, but the thread goes on to explain why this single decider version is better.
==== Backup steam example ====
This example will turn on the steam generator when the Accumulator charge drops to 20%, but will "latch" (remember) the On state until the accumulator is charged to 90%.

Latching is used to introduce [[Wikipedia:hysteresis|hysteresis]] and avoid the power switch rapidly cycling on and off (as the accumulator falls to 19%, charges to 20%, falls to 19% and so on).

* The [[lamp]] will light up with the colored signal that is greater than zero and earliest in this list: Red, Green, Blue, Yellow, Pink, Cyan, White.
* We have a [[Red wire]] per column, that wire has each of the colored signals on it at different values and a numbered signal for each row.
* There is a [[Arithmetic combinator]] for each cell that subtracts the "row" value from each of the colored signals.
* And this enables us to choose the color for each cell.
* Simple!

LowBattery: /* To set the light condition */

{{Languages}}
== Foreword ==

This page provides examples of simple circuit network designs and some not so simple designs that others can use, combine and modify. They are designed to be as easy to understand as possible. To see the settings of combinators without opening them, the option "Show combinator settings when detailed info is on" in the graphics options has to be checked and detailed info has to be turned on.

==Lamp showing chest content condition==
[[File:LightWiredToChest.png|right|218 × 412px]]

This is the simplest possible use of circuit-network. A lamp is light depending on the number of goods (in this example empty barrels) in a chest.

===Setting up circuit connection===
* The lamp is connected to the chest
* the lamp is set to light if the chest contain less than 10 empty barrels.
{{clear}}

[[File:LamponBarrelCondition.png|right|400x400px]]
===To set the light condition===
# open the lamp (right click on it)
# Set the input to barrels
# Set the operator to < (less than)
# Set the constant number:
## Right click on the constant number
## Move the slider until 10 is shown, or edit the value box directly
## Press set

Depending on the condition you set, the lamp may light if the chest is empty, or if it contains the required quantity of items.

The drawback with this scenario is that the lamp has a white light , and is therefore difficult to differentiate from an ordinary lamp at night.

== Oil Setups ==
[[File:LgtOilCracking.png|left|400x400px]]
=== Light Oil Cracking ===
* This circuit provides balanced light oil and petroleum gas production by cracking excess light oil into gas.
* The [[Pump]] is connected to the [[Storage tank]] by a [[Red wire]].
* The [[small pump]] has an enabled condition set to '''Light Oil > 2000'''.
{{clear}}

[[File:HvyOilCracking.png|left|400x400px]]

=== Heavy Oil Cracking ===
* This circuit extends on the previous circuit by adding optional heavy oil cracking to provide lubricant etc.
* The [[Pump]] has an enabled condition set to '''Heavy oil > 2000'''.
{{clear}}

[[file:BalancedPlasticSulfur.png|left|400x400px]]

=== Petroleum split evenly between plastic and sulphuric acid ===
* This circuit buffers gas in the tank until there is at least 100, then it lets the tank drain until there is less than 50 and the cycle repeats.
* It has a few elements that work together to do achieve this.
* Firstly the [[Pump]] is connected to the [[Wooden chest]] by a [[Red wire]] and the enabled condition on the [[Pump]] is set to '''Raw wood > 0'''.
* Both of the [[Inserter]]s are connected to the [[Storage tank]] by [[Red wire]]s.
* The enabled condition on the left inserter is '''Petroleum gas > 100'''
* The enabled condition on the right inserter is '''Petroleum gas < 50'''.
* You will need to insert a single "Raw wood" into the chest to make it all work.
<br />
* It is also possible to do this with [[decider combinator]]s instead of the inserters, belt and the Wood chest or even just belts.
{{clear}}

== Lights ==
[[File:ConditionalLights.png|left|400x400px]]
=== Conditional Lights ===
* In this circuit we connect a series of [[lamp]]s to a [[Storage tank]].
* By setting different conditions on each [[lamp]] we can build an indicator strip.
* The Enabled condition of the first [[lamp]] is '''Petroleum gas > 100'''.
* The others light up when gas is greater than 200, 300, 400 and 500 respectively.
{{clear}}

In this scenario you can connect the storage tank to the lamps directly.

=== Colored Lights ===
* To light a [[lamp]] with a color rather than white, you need an intermediate device like an [[Arithmetic combinator]] that can send a color signal.
Instead of directly connect the the [[Lamp]] and the [[Storage tank]] you need:<BR>
1 Add the [[Arithmetic combinator]].<BR>
2 Connect the [[Storage tank]] with the input of the [[Arithmetic combinator]].<BR>
3 Connect the output of the [[Arithmetic combinator]] with the [[lamp]].<BR>
4 Set up the [[Arithmetic combinator]]:<BR>
4.1 Setting the input to Petroleum Gas + 0 (the constant 0 not the signal 0)<BR>
4.2 Set the output to the Pink signal (on the bottom row of the last tab of signals.)<BR>
5 Set up the [[lamp]]:<BR>
5.1 Select the "Use colors" check box on the lamp.<BR>
5.2 Set the condition to the Pink signal, and what value you want (i.e. > 100)<BR>

== Misc ==
[[file:MulitipleChestsAndPoles.png|left|400x400px]]
=== Multiple Storages ===
* If you connect multiple chests to a pole, the pole displays the sum of items in all the chests.
* This also works with [[Storage tank]]s and [[roboport]]s.
{{clear}}

[[File:ConstantComb.png|left|400x400px]]

=== Constant combinator ===
* With a [[constant combinator]] you can generate any signals you may need.
* In this example we have generated a signal of 50 Laser turrets and 200 Piercing round magazine.
* Constant combinators are not of much use on their own but we shall use them later.
{{clear}}

[[File:LogicGates.png|left|400x400px]]

=== Logic gates ===
* In each case the two inputs can be connected with the same color wire or different colors. The inputs are powered by two [[Constant combinator]]s each of them output an A signal with value 1 for true and nothing or false.
* You can use [[Decider combinator]]s to make all of the common logic gates.
* The output for each should be set to 1 and the signal of your choice.
* Use the following settings to create different gates:
{{clear}}

NOT A=0
NOR A=0
NAND A<2
XOR A=1
AND A=2
OR A>0

{{clear}}

[[File:ThisASign.png|left|400x400px]]

=== Constant combinator signs ===
* You can use [[Constant combinator]]s to make signs, just set the letter signals in the combinator, each combinator can display 2 characters side by side.
{{clear}}

[[File:MemoryCell.png|left|400x400px]]

=== Memory Cell / Counter ===
* Basic memory cell that counts all the items moved by the inserter
* The [[Fast inserter]] is connected to '''BOTH''' ends of the arithmetic combinator.

* If the [[Fast inserter]] hasn't picked anything up this tick the input to the Arithmetic combinator is the same as and output and hence the values are persisted.
* When the [[Fast inserter]] does pick something up its value is added to the output from the previous tick thus incrementing that item.
{{clear}}

[[File:BeltCache.png|left|400x400px]]

=== Automatic Belt-Cache ===
* Some intermediate products are huge in demand during peak-production only. To bypass the need of providing a huge amount of factories in order to cover that peaks, a cache-unit can be used. The unit stores items, while the belt has backed up (so theres obviously no current demand downstream) and releases items as soon as the belt gets too empty.
* The blue area are 3 parts of Express belts. According to the wiki, each belt can hold up to 7.11 items. This means the feeding fast belt can not provide 7.11 items for the express belts as long as the belt is moving. (And while the belt is moving, we don't want to cache items, but let regular production run, or even release items from the cache.)
* This means, once the counters on the two express belts are 7.11 each, the belt has backed up, so we can start "caching" items into our storage array.
* For this purpose, the counters are connected to the arithmetic combinator (A) which multiples the input (*100) into green signals. So, if the belt has backed up, B shows ">1422" green signals.
* This is the activation condition for the Belt (C), which will redirect the input tp the storage array.
* Since items should only be released if the belt starts to clear, the counter (D) is evaluated by the belt (E) which is only activated, if item-count on (D) is smaller than 6 (this number has to be adjusted to personal needs, when the cache should become "active" and release items)
* The layout can be extended to cache whatever amount of items is required. (Some balancing for the release-method would be required ofc.)
{{clear}}

[[File:combinatorMultiplierDetailed.png|left|400x400px]]
=== Multiplier and Dictionaries/Arrays ===
* Multiplying two signals together is simple and requires only a single combinator, however multiplying a set of signals is more complicated.
* A proof is shown below for the equation and why it works.
* A dictionary is a system that allows a value on a specific signal to be accessed. For example, A can contain many signals (either from a constant combinator or memory cell) and B can contain 1 of a specific signal (such as blue signal). What remains is the blue-signal value from A. This is because all the other signals are multiplied by 0.
* Arrays are similar to dictionaries, but instead of using a signal as a key, we use a number. Constant combinators are placed mapping each signal to a unique number (such as 1 yellow belt, 2 red belt, 3 blue belt, 4 burner inserter, etc). Then, use a combinator of "each = index OUTPUT 1 of each" and plug that in as the input to a dictionary.
[[File:combinatorMultiplierMath.png|left|400x400px]]

((A+B)^2 - (A-B)^2)/4 = AB
(A+B)^2 - (A-B)^2 = 4AB
(A^2 + 2AB + B^2) - (A^2 - 2AB + B^2) = 4AB
4AB = 4AB

== Inserters ==
[[File:LimitItemsPlacedIntoAChest.png|left|400x400px]]
=== Limit items placed into a chest ===
* The [[Inserter]] is connected to the [[Wooden chest]] using a [[Red wire]].
* The inserter's enabled condition is '''Advanced Circuit < 10'''.
* In reality this means the inserter may place more than 10 Advanced circuits in the chest because it could pick up-to 3 at once.
* This effect can be even greater with Stack inserters because of their large carrying capacity.
* This technique still gives far greater control than limiting the inventory on the chest.
{{clear}}
=== Balanced chest insert ===
Goal: Load n chests with approximately the same number of items.
* Place n chests and n inserters.
* Place 1 [[Arithmetic combinator]]
* Set the combinator to take Each (yellow star) and divide by the negative number of chests. ie -n.
* Connect all chests to each other and to the input of the combinator using red wire.
* Connect all inserters to each other and to the output of the combinator using red wire.
* Connect each inserter to the box it inserts into with green wire.
* Set the enable condition on each inserter to be Everything (red star) < 0.

The combinator calculates the average number of items in the chests, and makes it negative. Each inserter gets the amount in the chest it is inserting to and adds the negative average, ie it calculates how many more than the average it has in its chest. Thus if that number is negative, it has less than the average in the chest and it enables.

Due to inserter stack bonus the count is not exact. If precise count is needed, set the inserter stack size to 1.

{{clear}}

[[File:SmartOutpostUnloader.png|left|400x400px]]
=== Keeping outpost stocked with specified items ===
* This circuit keeps a [[Storage chest]] at an outpost stocked with customized levels of different items.
* For example you could keep an outpost stocked with 50 laser turrets and 200 piercing magazine rounds but not have to worry about it being over filled.
* The [[storage chest]] is attached to the input of the [[Arithmetic combinator]] (left side in the picture) with a [[Red wire]].
* Another couple of [[Red wire]]s join the output of the [[Arithmetic combinator]] (right side) to the [[constant combinator]] and to the [[stack filter inserter]].
* The [[Arithmetic combinator]] '''multiples''' each input value (from the storage chest) by '''-1'''.
* Finally the filter stack inserter's mode of operation is set to '''Set filters'''.
<br />
* So the input to the [[stack filter inserter]] is '''<Constant combinator> - <Storage chest contents>''' and the filter is set to filter the item of greatest demand.
{{clear}}

[[File:SolarAccumalatorBalancer.png|left|400x400px]]

=== Balanced Solar panel / Accumulator Production ===
* This circuit balances production of [[Solar panel]]s and [[Accumulator]]s to a desired ratio in my case 24:20.
* The first [[Arithmetic combinator]] takes the number of accumulators in the chest and '''multiples''' it by '''24'''.
* The second [[Arithmetic combinator]] takes the output of the first combinator and '''divides''' it by '''20'''.
* This gives us the number of accumulators that we can directly compare to the number of Solar panels in both inserters.
* If the number of accumulators is greater we enable the Solar panels inserter, if the number of Solar panels is greater we enable the accumulators inserter.
* However, if they are equal, neither machine does anything. So we add a single accumulator to one of the inserters using a constant combinator and a wire of the other color, therefore breaking the deadlock.

== Sushi Belts ==
[[File:SushiScience1.png|left|400x400px]]
=== Reading Belt Design ===
* Six belts in a row are connected with Red wire and set to '''Read belts contents''' and '''Hold'''
* This [[Red wire]] is then connected to the inserters that insert onto the belt.
* Read hand contents is unselected for all inserters.
* Mode of operation is set to '''Enable/Disable''' on all inserters.
* The first inserter is enabled when '''Science pack 1 = 0'''
* The other inserters are set similarly for the other science packs.
{{clear}}

[[File:SushiScience2.png|left|400x400px]]
=== Memory Cell Design ===
* This circuit counts the number of items of each type on a looping belt by counting the numbers that are added and removed from the belt by inserters.
* Each inserter that takes items off the belt is connected together with Red wire and each of these inserters is set to '''Mode of operation none, Read hand content selected''' and '''Hand read mode pulse'''.
* These inserters are connected to the input of the left arithmetic combinator.
* The left [[Arithmetic combinator]] multiples '''each''' input by '''-1''' and outputs it to '''each'''.
* The right [[Arithmetic combinator]] is a '''memory cell''' as above.
* The memory cell's input is connected to the inserters that are placing items on the belt and the output of the left [[Arithmetic combinator]].
* The inserters that place items onto the belt have an enabled condition that is based on the number of items on the belt.
{{clear}}

== Splitters ==
[[file:CondSplitter.png|left|400x400px]]
=== Conditional splitter ===
* This is the most simple circuit you can have for "controlling" a splitter.
* A signal X=1 is transmitted from off screen when the items need to be sent down the belt.
* The belt on the left is enabled when X=1.
* The belt on the right is enabled when X=0.
* The two belts are wired together and to a pole.
{{clear}}

[[File:PrioritySplitter.png|left|400x400px]]
=== Priority Splitter ===
* This circuit prioritizes items to the belt going of the screen to the left but will send items straight on if the belt to the left is backed up.
* Its not perfect and will leak some items but its good enough for most applications.
* The balancer means it will work even if the supply or demand is uneven.
<br />
* It is critical that the belts are setup as in this picture otherwise it may not work.
{{clear}}

== Power ==
[[File:SteamBackup.png|left|400x400px]]
=== Backup steam power ===
* The [[steam engine]]s are not directly connected to the power network. They are connected to the power network through a [[Power switch]].
* The [[power switch]] is connected to one of the [[accumulator]]s in the main network.
* The [[power switch]] turns on when A < 10. That is when the [[accumulator]]s are less than 10% full.
{{clear}}
=== Optimal usage of fuel for nuclear power ===
Unlike the normal steam power that adjusts fuel usage based on power usage, the [[Power_production#Nuclear_power|nuclear reactors]] spend fuel in fixed units of time. To be exact, the consumption of 1 fuel cell takes exactly 200 seconds.

Combined with the fact that creating the nuclear fuel cells are time consuming and expensive to create, it is therefore beneficial to optimize their use to match the actual consumed power.

[[File:NuclearSetupWithCircuits.png]]

The above picture shows a setup with 4 reactors, that spend only 1 fuel cell each whenever steam backup runs low.

There are a couple of elements in this setup:

* 4 Storage tanks are connected with a wire, that is then connected to the substation. Each storage tank can contain 25.000 units of steam, for a total of 100.000 units. It is not necessary to connect more than 4 tanks, even though more tanks are added in the setup. However, connecting fewer is not recommended, since a single tank may fluctuate too much to give steady readings.
* 1 [[Tutorial:Circuit-network_Cookbook#SR_latch|SR-latch]], these are the 2 top-most combinators and the one on the right side. The low mark is set to 1.500 (1.5% of connected storage tank capacity) and the high mark to 5.000 (5% of connected storage tank capacity). The output can be anything except [[Used_up_uranium_fuel_cell|Empty fuel cell]]. In this example we output L (Made an error in the image, the trigger condition is of course L > H, not L < H). The inputs of the latch is connected to the substation, and so is the output.
This will trigger the response necessary during normal operation when we have enough fuel and have already started the reactors. The reason that we can have such low lower bound is that after start-up of the reactors the temperature will never drop below 500C, and thus immediately after a new fuel cell has been input the heat exchangers will start to generate more steam. The reason for the high mark to also be quite low is that we don't want it to trigger the insertion of another fuel cell until the previous one has been spent.
* 1 stand-alone combinator (The one on the left), which checks if amount of steam is < 200 (0.2% of connected storage tank capacity), and outputs 1 [[Used_up_uranium_fuel_cell|Empty fuel cell]]. The inputs of the combinator is connected to the substation, and so is the output.
This will trigger the response necessary during start up, and after running out of fuel.
* Output inserters that take [[Used_up_uranium_fuel_cell|Empty fuel cell]] from the reactor. This is connected to the substation (or any adjacent element that is then connected to the substation) and listens for the output of the SR-latch, ie. L > 0. Furthermore, it is setup to "read hand content" in "hold mode".
* Input inserters that put fuel into the reactor. This is connected to the substation (or any adjacent element that is then connected to the substation) and listens for the output of the output inserters OR the stand-alone combinator, ie. [[Used_up_uranium_fuel_cell|Empty fuel cell]] > 0. The "override input stack" is set to 1, so that it only inserts 1 fuel cell at a time.
This means that whenever the low mark is triggered, the output inserters will grab the empty fuel cell in the reactor, this then triggers the input inserters to insert a new cell. This only works if there IS an empty cell in the reactor, therefore the need for the stand-alone combinator to force always on of the input inserters, whenever the system previously ran out of the fuel, or is in start-up mode.
* 1 constant combinator to output whichever color you want the lights to be. This is not necessary at all, but looks nice.
* Lots of lamps to make it look nice, optionally setup to only turn on whenever steam level is at a given level to see storage.

== Latches ==
=== SR latch - single decider version ===
[https://forums.factorio.com/viewtopic.php?f=193&t=14556 This discussion] on the Factorio forums starts with the common 2 decider RS latch version, but the thread goes on to explain why this single decider version is better.
==== Backup steam example ====
This example will turn on the steam generator when the Accumulator charge drops to 20%, but will "latch" (remember) the On state until the accumulator is charged to 90%.

Latching is used to introduce [[Wikipedia:hysteresis|hysteresis]] and avoid the power switch rapidly cycling on and off (as the accumulator falls to 19%, charges to 20%, falls to 19% and so on).

* The [[lamp]] will light up with the colored signal that is greater than zero and earliest in this list: Red, Green, Blue, Yellow, Pink, Cyan, White.
* We have a [[Red wire]] per column, that wire has each of the colored signals on it at different values and a numbered signal for each row.
* There is a [[Arithmetic combinator]] for each cell that subtracts the "row" value from each of the colored signals.
* And this enables us to choose the color for each cell.
* Simple!

LowBattery: /* To set the light condition */

{{Languages}}
== Foreword ==

This page provides examples of simple circuit network designs and some not so simple designs that others can use, combine and modify. They are designed to be as easy to understand as possible. To see the settings of combinators without opening them, the option "Show combinator settings when detailed info is on" in the graphics options has to be checked and detailed info has to be turned on.

==Lamp showing chest content condition==
[[File:LightWiredToChest.png|right|218 × 412px]]

This is the simplest possible use of circuit-network. A lamp is light depending on the number of goods (in this example empty barrels) in a chest.

===Setting up circuit connection===
* The lamp is connected to the chest
* the lamp is set to light if the chest contain less than 10 empty barrels.
{{clear}}

[[File:LamponBarrelCondition.png|right|400x400px]]
===To set the light condition===
# open the lamp (right click on it)
# Set the input to barrels
# Set the operator to < (less than)
# Set the constant number:
## Right lick on the constant number
## Draw the slide until 10 is shown, or edit the value box directly
## Press set

Depending on the condition you set you may light the lamp if the barrel is empty, or contain a decent number of articles.

The draw back with this scenario is that the lamp have a white light , and is therefore difficult to differ from ordinary lamp at night.

== Oil Setups ==
[[File:LgtOilCracking.png|left|400x400px]]
=== Light Oil Cracking ===
* This circuit provides balanced light oil and petroleum gas production by cracking excess light oil into gas.
* The [[Pump]] is connected to the [[Storage tank]] by a [[Red wire]].
* The [[small pump]] has an enabled condition set to '''Light Oil > 2000'''.

[[File:HvyOilCracking.png|left|400x400px]]

=== Heavy Oil Cracking ===
* This circuit extends on the previous circuit by adding optional heavy oil cracking to provide lubricant etc.
* The [[Pump]] has an enabled condition set to '''Heavy oil > 2000'''.

[[file:BalancedPlasticSulfur.png|left|400x400px]]

=== Petroleum split evenly between plastic and sulphuric acid ===
* This circuit buffers gas in the tank until there is at least 100, then it lets the tank drain until there is less than 50 and the cycle repeats.
* It has a few elements that work together to do achieve this.
* Firstly the [[Pump]] is connected to the [[Wooden chest]] by a [[Red wire]] and the enabled condition on the [[Pump]] is set to '''Raw wood > 0'''.
* Both of the [[Inserter]]s are connected to the [[Storage tank]] by [[Red wire]]s.
* The enabled condition on the left inserter is '''Petroleum gas > 100'''
* The enabled condition on the right inserter is '''Petroleum gas < 50'''.
* You will need to insert a single "Raw wood" into the chest to make it all work.
<br />
* It is also possible to do this with [[decider combinator]]s instead of the inserters, belt and the Wood chest or even just belts.

* In this circuit we connect a series of [[lamp]]s to a [[Storage tank]].
* By setting different conditions on each [[lamp]] we can build an indicator strip.
* The Enabled condition of the first [[lamp]] is '''Petroleum gas > 100'''.
* The others light up when gas is greater than 200, 300, 400 and 500 respectively.
{{clear}}

In this scenario you can connect the storage tank to the lamps directly.

[[File:ColoredLights.png|left|400x400px]]

=== Colored Lights ===
* To light a [[lamp]] with a color rather than white, you need an intermediate device like an [[Arithmetic combinator]] that can send a color signal.
Instead of directly connect the the [[Lamp]] and the [[Storage tank]] you need:<BR>
1 Add the [[Arithmetic combinator]].<BR>
2 Connect the [[Storage tank]] with the input of the [[Arithmetic combinator]].<BR>
3 Connect the output of the [[Arithmetic combinator]] with the [[lamp]].<BR>
4 Set up the [[Arithmetic combinator]]:<BR>
4.1 Setting the input to Petroleum Gas + 0 (the constant 0 not the signal 0)<BR>
4.2 Set the output to the Pink signal (on the bottom row of the last tab of signals.)<BR>
5 Set up the [[lamp]]:<BR>
5.1 Select the "Use colors" check box on the lamp.<BR>
5.2 Set the condition to the Pink signal, and what value you want (i.e. > 100)<BR>

== Misc ==
[[file:MulitipleChestsAndPoles.png|left|400x400px]]
=== Multiple Storages ===
* If you connect multiple chests to a pole, the pole displays the sum of items in all the chests.
* This also works with [[Storage tank]]s and [[roboport]]s.
{{clear}}

[[File:ConstantComb.png|left|400x400px]]

=== Constant combinator ===
* With a [[constant combinator]] you can generate any signals you may need.
* In this example we have generated a signal of 50 Laser turrets and 200 Piercing round magazine.
* Constant combinators are not of much use on their own but we shall use them later.
{{clear}}

[[File:LogicGates.png|left|400x400px]]

=== Logic gates ===
* In each case the two inputs can be connected with the same color wire or different colors. The inputs are powered by two [[Constant combinator]]s each of them output an A signal with value 1 for true and nothing or false.
* You can use [[Decider combinator]]s to make all of the common logic gates.
* The output for each should be set to 1 and the signal of your choice.
* Use the following settings to create different gates:
{{clear}}

NOT A=0
NOR A=0
NAND A<2
XOR A=1
AND A=2
OR A>0

[[File:ThisASign.png|left|400x400px]]

=== Constant combinator signs ===
* You can use [[Constant combinator]]s to make signs, just set the letter signals in the combinator, each combinator can display 2 characters side by side.
{{clear}}

[[File:MemoryCell.png|left|400x400px]]

=== Memory Cell / Counter ===
* Basic memory cell that counts all the items moved by the inserter
* The [[Fast inserter]] is connected to '''BOTH''' ends of the arithmetic combinator.

* If the [[Fast inserter]] hasn't picked anything up this tick the input to the Arithmetic combinator is the same as and output and hence the values are persisted.
* When the [[Fast inserter]] does pick something up its value is added to the output from the previous tick thus incrementing that item.
{{clear}}

[[File:BeltCache.png|left|400x400px]]

=== Automatic Belt-Cache ===
* Some intermediate products are huge in demand during peak-production only. To bypass the need of providing a huge amount of factories in order to cover that peaks, a cache-unit can be used. The unit stores items, while the belt has backed up (so theres obviously no current demand downstream) and releases items as soon as the belt gets too empty.
* The blue area are 3 parts of Express belts. According to the wiki, each belt can hold up to 7.11 items. This means the feeding fast belt can not provide 7.11 items for the express belts as long as the belt is moving. (And while the belt is moving, we don't want to cache items, but let regular production run, or even release items from the cache.)
* This means, once the counters on the two express belts are 7.11 each, the belt has backed up, so we can start "caching" items into our storage array.
* For this purpose, the counters are connected to the arithmetic combinator (A) which multiples the input (*100) into green signals. So, if the belt has backed up, B shows ">1422" green signals.
* This is the activation condition for the Belt (C), which will redirect the input tp the storage array.
* Since items should only be released if the belt starts to clear, the counter (D) is evaluated by the belt (E) which is only activated, if item-count on (D) is smaller than 6 (this number has to be adjusted to personal needs, when the cache should become "active" and release items)
* The layout can be extended to cache whatever amount of items is required. (Some balancing for the release-method would be required ofc.)
{{clear}}

[[File:combinatorMultiplierDetailed.png|left|400x400px]]
=== Multiplier and Dictionaries/Arrays ===
* Multiplying two signals together is simple and requires only a single combinator, however multiplying a set of signals is more complicated.
* A proof is shown below for the equation and why it works.
* A dictionary is a system that allows a value on a specific signal to be accessed. For example, A can contain many signals (either from a constant combinator or memory cell) and B can contain 1 of a specific signal (such as blue signal). What remains is the blue-signal value from A. This is because all the other signals are multiplied by 0.
* Arrays are similar to dictionaries, but instead of using a signal as a key, we use a number. Constant combinators are placed mapping each signal to a unique number (such as 1 yellow belt, 2 red belt, 3 blue belt, 4 burner inserter, etc). Then, use a combinator of "each = index OUTPUT 1 of each" and plug that in as the input to a dictionary.
[[File:combinatorMultiplierMath.png|left|400x400px]]

((A+B)^2 - (A-B)^2)/4 = AB
(A+B)^2 - (A-B)^2 = 4AB
(A^2 + 2AB + B^2) - (A^2 - 2AB + B^2) = 4AB
4AB = 4AB

== Inserters ==
[[File:LimitItemsPlacedIntoAChest.png|left|400x400px]]
=== Limit items placed into a chest ===
* The [[Inserter]] is connected to the [[Wooden chest]] using a [[Red wire]].
* The inserter's enabled condition is '''Advanced Circuit < 10'''.
* In reality this means the inserter may place more than 10 Advanced circuits in the chest because it could pick up-to 3 at once.
* This effect can be even greater with Stack inserters because of their large carrying capacity.
* This technique still gives far greater control than limiting the inventory on the chest.
{{clear}}
=== Balanced chest insert ===
Goal: Load n chests with approximately the same number of items.
* Place n chests and n inserters.
* Place 1 [[Arithmetic combinator]]
* Set the combinator to take Each (yellow star) and divide by the negative number of chests. ie -n.
* Connect all chests to each other and to the input of the combinator using red wire.
* Connect all inserters to each other and to the output of the combinator using red wire.
* Connect each inserter to the box it inserts into with green wire.
* Set the enable condition on each inserter to be Everything (red star) < 0.

The combinator calculates the average number of items in the chests, and makes it negative. Each inserter gets the amount in the chest it is inserting to and adds the negative average, ie it calculates how many more than the average it has in its chest. Thus if that number is negative, it has less than the average in the chest and it enables.

Due to inserter stack bonus the count is not exact. If precise count is needed, set the inserter stack size to 1.

{{clear}}

[[File:SmartOutpostUnloader.png|left|400x400px]]
=== Keeping outpost stocked with specified items ===
* This circuit keeps a [[Storage chest]] at an outpost stocked with customized levels of different items.
* For example you could keep an outpost stocked with 50 laser turrets and 200 piercing magazine rounds but not have to worry about it being over filled.
* The [[storage chest]] is attached to the input of the [[Arithmetic combinator]] (left side in the picture) with a [[Red wire]].
* Another couple of [[Red wire]]s join the output of the [[Arithmetic combinator]] (right side) to the [[constant combinator]] and to the [[stack filter inserter]].
* The [[Arithmetic combinator]] '''multiples''' each input value (from the storage chest) by '''-1'''.
* Finally the filter stack inserter's mode of operation is set to '''Set filters'''.
<br />
* So the input to the [[stack filter inserter]] is '''<Constant combinator> - <Storage chest contents>''' and the filter is set to filter the item of greatest demand.
{{clear}}

[[File:SolarAccumalatorBalancer.png|left|400x400px]]

=== Balanced Solar panel / Accumulator Production ===
* This circuit balances production of [[Solar panel]]s and [[Accumulator]]s to a desired ratio in my case 24:20.
* The first [[Arithmetic combinator]] takes the number of accumulators in the chest and '''multiples''' it by '''24'''.
* The second [[Arithmetic combinator]] takes the output of the first combinator and '''divides''' it by '''20'''.
* This gives us the number of accumulators that we can directly compare to the number of Solar panels in both inserters.
* If the number of accumulators is greater we enable the Solar panels inserter, if the number of Solar panels is greater we enable the accumulators inserter.
* However, if they are equal, neither machine does anything. So we add a single accumulator to one of the inserters using a constant combinator and a wire of the other color, therefore breaking the deadlock.

== Sushi Belts ==
[[File:SushiScience1.png|left|400x400px]]
=== Reading Belt Design ===
* Six belts in a row are connected with Red wire and set to '''Read belts contents''' and '''Hold'''
* This [[Red wire]] is then connected to the inserters that insert onto the belt.
* Read hand contents is unselected for all inserters.
* Mode of operation is set to '''Enable/Disable''' on all inserters.
* The first inserter is enabled when '''Science pack 1 = 0'''
* The other inserters are set similarly for the other science packs.
{{clear}}

[[File:SushiScience2.png|left|400x400px]]
=== Memory Cell Design ===
* This circuit counts the number of items of each type on a looping belt by counting the numbers that are added and removed from the belt by inserters.
* Each inserter that takes items off the belt is connected together with Red wire and each of these inserters is set to '''Mode of operation none, Read hand content selected''' and '''Hand read mode pulse'''.
* These inserters are connected to the input of the left arithmetic combinator.
* The left [[Arithmetic combinator]] multiples '''each''' input by '''-1''' and outputs it to '''each'''.
* The right [[Arithmetic combinator]] is a '''memory cell''' as above.
* The memory cell's input is connected to the inserters that are placing items on the belt and the output of the left [[Arithmetic combinator]].
* The inserters that place items onto the belt have an enabled condition that is based on the number of items on the belt.
{{clear}}

== Splitters ==
[[file:CondSplitter.png|left|400x400px]]
=== Conditional splitter ===
* This is the most simple circuit you can have for "controlling" a splitter.
* A signal X=1 is transmitted from off screen when the items need to be sent down the belt.
* The belt on the left is enabled when X=1.
* The belt on the right is enabled when X=0.
* The two belts are wired together and to a pole.
{{clear}}

[[File:PrioritySplitter.png|left|400x400px]]
=== Priority Splitter ===
* This circuit prioritizes items to the belt going of the screen to the left but will send items straight on if the belt to the left is backed up.
* Its not perfect and will leak some items but its good enough for most applications.
* The balancer means it will work even if the supply or demand is uneven.
<br />
* It is critical that the belts are setup as in this picture otherwise it may not work.
{{clear}}

== Power ==
[[File:SteamBackup.png|left|400x400px]]
=== Backup steam power ===
* The [[steam engine]]s are not directly connected to the power network. They are connected to the power network through a [[Power switch]].
* The [[power switch]] is connected to one of the [[accumulator]]s in the main network.
* The [[power switch]] turns on when A < 10. That is when the [[accumulator]]s are less than 10% full.
{{clear}}
=== Optimal usage of fuel for nuclear power ===
Unlike the normal steam power that adjusts fuel usage based on power usage, the [[Power_production#Nuclear_power|nuclear reactors]] spend fuel in fixed units of time. To be exact, the consumption of 1 fuel cell takes exactly 200 seconds.

Combined with the fact that creating the nuclear fuel cells are time consuming and expensive to create, it is therefore beneficial to optimize their use to match the actual consumed power.

[[File:NuclearSetupWithCircuits.png]]

The above picture shows a setup with 4 reactors, that spend only 1 fuel cell each whenever steam backup runs low.

There are a couple of elements in this setup:

* 4 Storage tanks are connected with a wire, that is then connected to the substation. Each storage tank can contain 25.000 units of steam, for a total of 100.000 units. It is not necessary to connect more than 4 tanks, even though more tanks are added in the setup. However, connecting fewer is not recommended, since a single tank may fluctuate too much to give steady readings.
* 1 [[Tutorial:Circuit-network_Cookbook#SR_latch|SR-latch]], these are the 2 top-most combinators and the one on the right side. The low mark is set to 1.500 (1.5% of connected storage tank capacity) and the high mark to 5.000 (5% of connected storage tank capacity). The output can be anything except [[Used_up_uranium_fuel_cell|Empty fuel cell]]. In this example we output L (Made an error in the image, the trigger condition is of course L > H, not L < H). The inputs of the latch is connected to the substation, and so is the output.
This will trigger the response necessary during normal operation when we have enough fuel and have already started the reactors. The reason that we can have such low lower bound is that after start-up of the reactors the temperature will never drop below 500C, and thus immediately after a new fuel cell has been input the heat exchangers will start to generate more steam. The reason for the high mark to also be quite low is that we don't want it to trigger the insertion of another fuel cell until the previous one has been spent.
* 1 stand-alone combinator (The one on the left), which checks if amount of steam is < 200 (0.2% of connected storage tank capacity), and outputs 1 [[Used_up_uranium_fuel_cell|Empty fuel cell]]. The inputs of the combinator is connected to the substation, and so is the output.
This will trigger the response necessary during start up, and after running out of fuel.
* Output inserters that take [[Used_up_uranium_fuel_cell|Empty fuel cell]] from the reactor. This is connected to the substation (or any adjacent element that is then connected to the substation) and listens for the output of the SR-latch, ie. L > 0. Furthermore, it is setup to "read hand content" in "hold mode".
* Input inserters that put fuel into the reactor. This is connected to the substation (or any adjacent element that is then connected to the substation) and listens for the output of the output inserters OR the stand-alone combinator, ie. [[Used_up_uranium_fuel_cell|Empty fuel cell]] > 0. The "override input stack" is set to 1, so that it only inserts 1 fuel cell at a time.
This means that whenever the low mark is triggered, the output inserters will grab the empty fuel cell in the reactor, this then triggers the input inserters to insert a new cell. This only works if there IS an empty cell in the reactor, therefore the need for the stand-alone combinator to force always on of the input inserters, whenever the system previously ran out of the fuel, or is in start-up mode.
* 1 constant combinator to output whichever color you want the lights to be. This is not necessary at all, but looks nice.
* Lots of lamps to make it look nice, optionally setup to only turn on whenever steam level is at a given level to see storage.

=== SR latch - single decider version ===
[https://forums.factorio.com/viewtopic.php?f=193&t=14556 This discussion] on the Factorio forums starts with the common 2 decider RS latch version, but the thread goes on to explain why this single decider version is better.
==== Backup steam example ====
This example will turn on the steam generator when the Accumulator charge drops to 20%, but will "latch" (remember) the On state until the accumulator is charged to 90%.

Latching is used to introduce [[Wikipedia:hysteresis|hysteresis]] and avoid the power switch rapidly cycling on and off (as the accumulator falls to 19%, charges to 20%, falls to 19% and so on).

LowBattery: /* Devices */

{{Languages}}
'''Circuit networks''' are built using red or green wire, and enable the control of receivers, based upon information broadcast onto the network by connected senders. Most senders are storage devices, and broadcast their information onto a specific channel, based on the item or liquid the storage device contains. Each circuit network contains a channel for every kind of item, as well as 45 extra [[#Virtual signals|Virtual signals]] which act as user-definable channels. 'Everything', 'Anything' and 'Each' are also available wildcards.

[[File:InnerOfGreenCable.jpg|right|thumb|400px|A player drawn visualization of the interior of a circuit cable.]]

== Usage ==
=== Send Information ===
Senders broadcast the amount of items or fluids they contain or other data definable by the player. Each amount is broadcast as a numeric value on a 'channel' corresponding to the item. For example, a Storage Tank containing 1000 Crude Oil will broadcast 1000 on the Crude Oil channel.

The channels are separated from each other, so each network can simultaneously carry a number for each item and fluid in the game, and for each of the extra user-defined channels (digits 0-9, letters A-Z, and 9 different colors). All unused channels have the value zero.

Multiple broadcasts of the same item or fluid are additive: If there are two connected Storage Tanks with 1000 Crude Oil each, the value of the Crude Oil channel within the network will be 2000.

All wires of the same color which are connected together by junctions form a network, i.e. they will pass their signals to each other. For example, if two red wires are connected to the same combinator input, each wire receives the content from the other. This can result in feedback if care is not taken; see Feedback (under Arithmetic Combinator, below) for discussion.

Numbers are in the signed 32 bit integer range, i.e. from -2147483648 to 2147483647 inclusive. The numbers wrap around on overflow, so e.g. 2147483647 + 10 becomes -2147483639.

=== Control Devices ===
Receivers can use broadcast information, in most cases to enable/disable the device.

They can either compare results between different channels, or compare a channel to a specific value.

Receiving devices sum all signals from each wire connected to them, even red and green wires. For example, if an inserter is connected to a red wire carrying a signal for 20 iron plates, a green wire with 10 copper plates and another green wire with 5 iron plates, the input signal set for that receiver will be 25 iron plates and 10 copper plates.

== Devices ==

By clicking the left icon, you have access to the circuit network settings (if one is connected), by clicking the right icon, you have access to the logistic network settings, if one is reachable. There can be set conditions for both circuit (signals of red and green wires are summed) and logistic network, which will together act as a logical AND.

These devices can interact with the circuit network:

== Physical network structure ==
A circuit network consists only of those devices connected together with the same color wire. Wire can be strung directly from device to device, or across any intervening power poles. Wire length is limited by its previous connection.

Note that each connected set of wires forms a separate network. For example, it's entirely possible to have four red-wire networks and three green-wire networks. If red and green wires happen to touch the same power pole or device, the red and green networks will remain separate and will not link up . However, two red cables or two green cables will link if they touch. Use different colored cables to separate networks in close proximity.

* To connect wires or cables to a power pole, simply click on one entity, then on the base of the power pole.
* To erase a wire or cable connection, place the same color wire over an existing connection. You don't get the wire/cable back.
* To remove '''all''' connections from a power pole, shift-click on the pole. The first shift-click will remove all electrical connections, and the second will remove all red and green wires. You don't get the wires back.
* When connecting to a [[Arithmetic Combinator]] or [[Decider combinator]], take care to connect the wire to the correct input or output side. Use ALT-Key-Mode to see direction of combinator.
* Hovering the mouse cursor over an item will highlight all wires which form the network of the item.
* Hovering the mouse cursor over a power pole which is part of a network will display the signals on its network. Some items like combinators will also display their input and output signals when hovered over.

== Combinators ==
Combinators can function as both receiving and sending devices and allow more advanced functions to be used on a circuit network.

*The [[Constant combinator]] broadcasts up to 15 values on any of the channels for whatever networks it is connected to. (You cannot currently specify whether a value should be on the red or green channel; if you need different values, use two combinators, one for each color wire.) You can use any item channel or any of the [[Automatic control/Virtual signals|virtual signal]] channels.
**Note that using two of the 15 slots to broadcast values on the '''same''' channel is the same as broadcasting the sum of the two values from one slot.

*The [[Arithmetic Combinator]] performs arithmetic operations on input values and broadcasts the result to the specified output channel. The input and output channels can be any item channel or any of the virtual signal channels.
** Connecting: The Arithmetic Combinator connects to a red or green network on its '''input''' side (the terminals are set into the main body and look like spark plugs) and performs an arithmetic calculation which is broadcast into the specified channel on its '''output''' side (the output wires appear to stretch out a bit from the body of the device).
** Feedback: Note that the input network and the output network '''are not the same network'''. Connecting the output network back to the input network will result in a feedback loop. For example, adding 1 to the value for Copper Plates and broadcasting it as Copper Plates is an action that results in an infinite loop if output is connected back to input. The value for Copper Plates will rapidly (but not instantly) shoot upward. (Fun fact: The rate at which it climbs is the current tick rate) This technique can be combined with Decider Combinator logic to make electronic clocks, gates, and other systems; see [[Combinator Tutorial]] for advanced techniques.
** Each: This combinator can use the 'Each' signal for both input and output, in which case '''all''' non-zero input channels will have the combinator's operation performed and broadcast on the output side. Having Each signals for input and output and using a non-changing operation (like adding zero) is equivalent to having a 'one-way' wire; all the information from the input network is copied to the output network, but the reverse is not true.
**Multi-network: The Arithmetic Combinator can be joined to both red and green networks on the input side and will sum their inputs.

*The [[Decider combinator]] functions much like an Arithmetic Combinator, but is designed to compare values. Essentially, it is a conditional. In terms of Connecting, Feedback, and the Each signal it functions as specified above. In addition, it can handle the Everything and Anything signals, and performs more complex functions than summing when attached to multiple networks. See the [[Decider combinator]] page for more details on how to use this.

== Virtual signals ==

Virtual signals are special non-item signals. Other than the three logic signals, virtual signals do not behave differently from item signals.

45 virtual signals can be sent over a network. They include the digits zero through nine, the letters A through Z and the colors red, green, blue, yellow, magenta, cyan, white, gray and black.

=== Logic signals ===
[[File:logic_signals.png|300px|thumb|The icons of the three logic signals]]
Three of the virtual signals cannot be sent over a network but apply special logic to multiple signals.

==== Everything ====
''Everything'' can be used on the left side in conditionals. The condition will be true when the condition is true for each input signal. The condition is also true if there are no signals. This means that the ''everything'' signal behaves as [[:Wikipedia:universal quantification|universal quantification]].

The output of a [[decider combinator]] may also use ''everything''. When used the combinator will output all signals that pass the condition. The ''everything'' and ''anything'' signals are the only signals used in conditions that can make multiple signals pass a condition.

==== Anything ====
''Anything'' can be used on the left side of conditions. The condition will be true when the condition is true for at least one signal. This means the ''anything'' signal behaves as [[:Wikipedia:existential quantification|existential quantification]].

==== Each ====
''Each'' can only be used in left input side and output of [[decider combinator|decider]] and [[arithmetic combinator|arithmetic]] combinators. The signal can only be used as output when also used as input. When used in both the input and output it makes a combinator perform its action on each input signal individually. The combinator will output the sum of each of the actions if only used in the input.

== Tutorials ==
'''[[Circuit-network Cookbook|Circuit Network Cookbook]]''' - ''Example heavy tutorials; for beginners who want to get to know and use the benefits of the Circuit Network.''

'''[[Combinator Tutorial]]''' - ''Mainly textual and detailed tutorials.''

== Logistic Network ==
The Logistic network used by [[Logistic robot|Logistic robots]] is essentially a third network (a wireless one), along with the green and red wired network. The Logistic Network is based on proximity to a central [[Roboport]].

Some devices can also be connected to the logistic network. If a device has conditions set for circuit and for logistic network, it will become activated if both conditions are true.

See [[Logistic network]] and [[Roboport]] for more information.

Fuel

2017-04-06T10:52:26Z

LowBattery:

{{Languages}}
[[Fuel]] can be inserted into [[burner devices]] and burned to power them. Different types of Fuel provide different amounts of energy, measured in megajoules (MJ). A megajoule (MJ) is equivalent to one megawatt second (MWs), so dividing the megajoule (MJ) value by the power consumption in megawatts (MW) gives the time the fuel will last.

== Types ==
This is a list of all [[Items]] usable as [[Fuel]] in burner devices, ordered by fuel value:
{| class="wikitable"
! Item !! Fuel value !! Fuel value per raw total
|-
| {{imagelink|wood|Wood}} || 2 MJ || 4 MJ per raw wood
|-
| {{imagelink|raw-wood|Raw wood}} || 4 MJ || 4 MJ per raw wood
|-
| {{imagelink|wooden-chest|Wooden chest}} || 6 MJ || 3 MJ per raw wood
|-
| {{imagelink|coal|Coal}} || 8 MJ || 8 MJ per coal
|-
| {{imagelink|solid-fuel|Solid fuel}} || 25 MJ || 20 MJ per unit of [[Crude oil]] *
|-
| {{imagelink|small-electric-pole|Small electric pole}} || 4 MJ || 4MJ per raw wood
|-
| {{imagelink|rocket-fuel|Rocket fuel}} || 225 MJ ||
|}

(*) This assumes the Crude oil is processed completely into Solid fuel, using [[Advanced oil processing]] and [[Heavy oil cracking]] as intermediate steps, but not [[Light oil cracking]]. Less efficient methods are possible. In practice, the [[Petroleum Gas]] part of processed crude oil is more likely to be used for something other than Solid fuel.

LowBattery: /* Changes */

__NOTOC__

== 0.10.12 ==

=== Bugfixes ===
* Fixed that it wasn't possible to set a filter.
* Fixed that fast replacing moved items primary to character, it made upgrading chests and machines not practical. Instead, when fast replacing, the content is always transferred to the new entity, when it can't fit, it transfers to player, and if it can't be moved to the player as well it makes the good old item bomb.
* The right UI container is slightly larger, so it can contain the robot info without enlarging.
* The worm turrets are not taken into consideration when deciding enemy expansions.
* Fixed that enemy expansion candidates were not updated correctly when base was destroyed.
* Fixed that combat robots were on the map/minimap.
* Fixed extra mousebuttons over GUI behavior (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5810).
=== Balancing ===
* The maximum distance of enemy expansion was increased from 5 to 7.
=== Scripting ===
* makefile, takescreenshot and removepath now use logger to report failures, minor fixes in the path verification

== 0.10.11 ==

=== Bugfixes ===
* Fixed that number keys and enter were sometimes randomly not working (http://www.factorioforums.com/forum/viewtopic.php?t=5767).
* Fixed that the pipe to ground was missing the health bar (http://www.factorioforums.com/forum/viewtopic.php?t=5768).
* Fixed crash on mouse over ghost of rail signal that was connected to rail destroyed afterwards (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5766).

* Fixed the crash when the selection window of filter slots of cargo wagon is opened while the cargo wagon gets away (or id destroyed) and the filter is selected. Now the crash doesn't occur and the window is closed automatically (http://www.factorioforums.com/forum/viewtopic.php?t=5787).
* Show the logistic network areas when the deconstruction tool is in hand (http://www.factorioforums.com/forum/viewtopic.php?t=5779).
* Fixed that the long entity names permanently enlarged the sidebar (http://www.factorioforums.com/forum/viewtopic.php?t=5786).
* Fixed that downgrading container containing enough items to not fit into the inventory resulted in both the new and old container on the same spot (http://www.factorioforums.com/forum/viewtopic.php?t=5800).
* Fixed that wire connection isn't cleared when the wire is put away in godmode (http://www.factorioforums.com/forum/viewtopic.php?t=5801&).
* Fixed that cursor for wire placing was inconsistent sometimes (http://www.factorioforums.com/forum/posting.php?mode=reply&t=5802).

== 0.10.10 ==

'''There is a problem with numbers/enter hotkeys that can be randomly disabled for the whole game.

=== Bugfixes ===
* Fixed that passive provider chest acted as active provider chest after game load.
* Fixed that player turrets could be walked through after reconstructed. (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5618).
* Fixed that the starting chest in sandbox mode didn't contain some of the items in full stacks.
* Fixed that the pause game control reset itself to default after every restart.
* Fixed wrong directory name inside save (it was "currently-saving", now is the same as the save name)
* Fixed that map2scenario didn't copy locale and script state to the scenario.
* Fixed crash related to enemy pathfinding.
* Fixed of wrongly reported amount of items the player got from mining machines/containers (http://www.factorioforums.com/forum/viewtopic.php?t=5688).
* Fixed entity icons of defender/distractor/destroyer robots.
* Fixed that deconstructing transport-belt-to-ground would delete items they held (http://www.factorioforums.com/forum/viewtopic.php?t=5667).
* Fixed that deconstructing inserters holding items would delete items they held (http://www.factorioforums.com/forum/viewtopic.php?t=5636).
* The notifications of destroyed buildings are created only when someone other than player (or his machines) destroyed the building. This affects player destroying his buildings manually and also land-mine destroying itself on impact.
* Fixed, that slightly more robots than needed could be send to empty provider chest (http://www.factorioforums.com/forum/viewtopic.php?t=5613).
* When unresearching (using script) the toolbelt, the items that can't fit it are inserted back into the player's inventory (http://www.factorioforums.com/forum/viewtopic.php?t=5659).
* Recipes changed by mods will be refreshed to original value automatically when mod is removed (http://www.factorioforums.com/forum/viewtopic.php?t=5676).
* Fixed crash, when opening save that contained mods that are not already present, that had the active crafting group selected to group presented by the mod (so it is not present anymore), the crash occurred when the crafting menu was opened.
* Fixed that items were moved into quickbar even when there was already stack of the type in quickbar (currently selected in hand) (http://www.factorioforums.com/forum/viewtopic.php?t=5661)
* Fixed the missing check of gun->ammo compatibility when putting the gun there using shift-click or when the gun was crafted (http://www.factorioforums.com/forum/posting.php?mode=reply&f=7&t=5682).
* Fixed that the visualization radius of throwables (the green circle) wasn't visible when the player was in vehicle (http://www.factorioforums.com/forum/viewtopic.php?t=5595).
* Fixed that the inventory didn't get sorted after the container couldn't be mined as all the items couldn't fit the inventory (http://www.factorioforums.com/forum/viewtopic.php?=5614).
* Fixed that when enemy unit was modded to attack by destroying everything including itself crashed the game (http://www.factorioforums.com/forum/viewtopic.php?t=5727)
* Fixed that the player mined item event was not called when he got just part of the inventory (http://www.factorioforums.com/forum/viewtopic.php?t=5608).
* Fixed that it wasn't possible to start fullscreen game in other than the primary window. There is now settings in config in category [graphics] section: preferred-screen-index. Changing the value changes the display adapter (monitor) that is used. If many people use this feature in the future, we can put it in the graphics settings ingame as well (http://www.factorioforums.com/forum/viewtopic.php?t=5048).
* The number input box "consumes" only numeric input, other keys for walking or closing the still works when the field is selected. This is true as long as these are not mapped to numbers, bad luck in that case (http://www.factorioforums.com/forum/viewtopic.php?t=5741)
* Fixed that actions made in the last tick before closing the scenario due to error were applied again when different game was opened (http://www.factorioforums.com/forum/viewtopic.php?t=5741).
=== Debugging ===
* Added option to turn off vertical synchronization of the display (v-sync).
* Fixed crash when starting game without config file.
=== GUI ===
* Progress bar showing electricity availability is now colored. Green for all required energy available, yellow, more than half, red less than half)
=== Modding ===
* Progress bar style enables to specify different colors for different ranges of values.
=== Scripting ===
* Added game.getchunks() iterator and game.ischunkgenerated(...) and game.player.force.ischunkcharted() methods
* Pre player mined item event is called really before the player starts to get items from the inventory. Note that the change means, that the event is called even when the mine can eventually fail (not enough inventory to hold all the items). This means, that there might we could also other some other event, that will be called only when the entity is really going to be removed.

== 0.10.9 ==

=== Bugfixes ===
* Fixed crash when the map exchange string is not valid. If is not valid, text color is changed to red.
* Fixed the loading of saves containing inner saves (used in tightspot scenario) (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5482).
* Fixed that unresearching quickbar slots crashed the game (http://www.factorioforums.com/forum/viewtopic.php?t=5466).
* Fixed crash in map editor when building transport belts after building diagonal rail tracks (http://www.factorioforums.com/forum/viewtopic.php&t=5462).
* Fixed crash when entity with no icon shown in the electric network statistics, error icon is shown instead in that case (http://www.factorioforums.com/forum/viewtopic.php?t=5490).
* Fixed crash when some modded entity attack_reaction effect killed the attacking biter.
* Fixed various problems of not loadable save when energy source type of entities changed or mod specifying entities with energy source missing. (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5511).
* Removed so called "item bomb" effect. It happened When the player tried to a mine chest that contained items that couldn't fit his inventory. Instead of dropping all the items on the ground around (which could be A LOT of items in some cases), the mining just fails, while player gets as many items from the chest as possible.
* Fixed performance when cancelling large crafting queues and the player has no room to hold the items. This also fixes performance when a loot-enabled entity dies and drops a large amount of loot.
* Fixed bug when sometimes rail segments were messed up by placing rail signals from blueprint (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5350). Also blueprint which would place two signals next two each other cannot be placed.
* Fixed bug when train was self-damaging when driving backwards at the end of the rail (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5179). This also fixes the resulting crash when the wagon was destroyed.
* Fixed bug when train with 2 locomotives with opposite directions was not moving backwards when first locomotive had no coal.
* Fixed that laser turrets were not working when built near chunk boundaries (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5362).
* Saving the crc in the replay only once per second, so the replay (and save) size shouldn't grow so fast.
* Fixed that the beacon rotating animation was sometimes drawn under the beacon (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5431).
* Fixed bug where placing assembling machine over assembling machine of the same type could result into repetitive placing (http://www.factorioforums.com/forum/posting.php?mode=reply&f=7&t=5479).
* Fixed the problem with deconstruction of transport belt with inserter (or something other) putting items on it (http://www.factorioforums.com/forum/viewtopic.php?t=3090)
* Fixed that logistic robots were confused when inserting into storage with damaged items (http://www.factorioforums.com/forum/viewtopic.php?t=5326).
* Fixed that construction/logistic robots inside a network that was removed weren't re-assigned to the closest logistic network (http://www.factorioforums.com/forum/viewtopic.php?t=3088).
* The created effect of entities is not applied in map editor, to avoid too much freezed smoke particles at the same time that slows the render (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5492).
* Worms don't collide with the world during the dying animation (http://www.factorioforums.com/forum/viewtopic.php?t=5409).
* Worms don't show healthbar and don't regenerate health during the dying animation.
* Fixed scrolling with sliders in game (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5392).
* Fixed bug when some controls didn't work with mouse over the GUI (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5130) Now they work just fine unless there is a GUI action (i.e. crafting, transfer) with the same binding.
* Fixed extremely low placement probabilities of worms.
* Fixed resetting key bindings when changing keyboard layouts (http://www.factorioforums.com/forum/viewtopic.php?f=30&t=5192)
* Fixed bug when using deconstruction tool broke the replay (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5570&p=42998#p42998).
* Fixed that pausing the game closed the opened GUI (http://www.factorioforums.com/forum/viewtopic.php?t=5563)
* Fixed that setting more than 65535 value in the logistics request GUI didn't work properly.
* Fixed that the number in the logistic GUI wasn't set to 0 when the slot was cleared (http://www.factorioforums.com/forum/viewtopic.php?t=5565).
* Map map2scenario reports errors correctly instead of crashing.
* Using map2scenario no longer resets researched technologies and unlocked recipes.
* Migrations are applied even when using map2scenario.
* Fixed bug when blueprints were "looting" the items from transport belt to grounds (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5587).
=== Debugging ===
* Added show_active_chunks debug option, shows which chunks are active on the big map.
=== Scripting ===
* Fixed that caninsert method ignored set filters (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5477).
* Fixed that LuaForce:reset didn't reset all the force modifiers. Namely: inserter stack size bonus, logistic slots, quickBarCount, followingRobotsCount, ghost time to live.

== 0.10.8 ==

=== Bugfixes ===
* Fixed bug on windows when game couldn't be saved

== 0.10.7 ==
'''EDIT: This is probably the shortest-lived release we had. There was a serious bug (http://www.factorioforums.com/forum/viewtopic.php?f=30&t=5383) when saving on windows didn't work (and many people wanted to do that). So we have released the hotfix version: http://www.factorioforums.com/forum/viewtopic.php?f=3&t=5386.'''

* Old save file is not overwritten when saving fails (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5354).
* Fast replacing assembling machine keeps the direction of the original assembling machine. This is because the common scenario here is to upgrade the assembling machine, rather than use it to change direction of existing machines (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=5239).
* Allowed to check placebility of item on ground from script as long as the item is specified (http://www.factorioforums.com/forum/viewtopic.php?f=30&t=5238).

== 0.10.2 ==

Another (mostly) bugfix release, most of the critical bugs should be resolved, but it is still not a release candidate as there are still obvious bugs in our bug reports.

'''The automatic update system was messed up in the 0.10.0 and 0.10.1. As a result now it is working only partially: OSX, Linux for 0.10.1 -> 0.10.2 should work, the rest is downloadable from http://www.factorio.com/download/experimental as full package.

=== Bugfixes ===
* Fixed the crash when opening save with active replay saving.
* Fixed crash when smart inserter with logistic condition was rebuilt.

* Fixed that splitter was buildable over transport belt to ground (and vice versa).
* Fixed crash when renaming OSX application name.
* Rotation of turrets doesn't play role when deciding if the part of the overlapping blueprint doesn't collide. Rotation of other entities like belts, inserters etc. still matters.
* Fixed that the underground belt cover did have the same graphics regardless if it was input or output.
* Fixed that the underground belt direction when building to be connected with different underground didn't have the preview direction correct (both in blueprint and manual building).
* Fixed wrong blueprint positioning when it contained rail/stations and was created just from ghost entities.
* Fixed crash when showing tooltip of construction material warning for unbuildable entities.
* Locomotive recalculates path on rotation.
* Fixed pump collision box so they can be built next to each other.

* Fixed crash when placing rail signal for rail loop (http://www.factorioforums.com/forum/viewtopic.php?f=7&t=3482).
* Fixed crashes when attempting to use construction robots to deconstruct rails under a train.
* Not showing energy for flying robots that don't use energy (combat robots).
* Fixed corrupted save problem that occurred when the player had follower robots active, was in a car that had blueprint with roboport in the trunk. Saves corrupted this way from earlier versions are not loadable.
== Changes ==
* Changed the prioritization of resupplying source of logistic robots. Provider has biggest priority, then storage and the last one is passive provider. This is to avoid uncontrolled filling of storage chests from the leftovers.
== Graphics ==
* More realistic train light drawing (light cone in the front, red light in the back).
== Balancing ==
* Wall repair speed is twice the fast.
== Translations ==
* Added Catalan translation.

== 0.10.0 ==

=== Beware of the trailer mod ===

The trailer mod changes the game properties significantly. If you have it enabled it can cause some very strange behavior in your existing games (different recipes, different consumption, different speeds of vehicles, etc.). Use it only to preview the trailer scenario!

=== Features ===
* Environment sounds. Active machines close to the player create a small factory orchestra.
* Proper volume settings for master volume / effects volume / etc.

=== Sound ===
* Working sounds for most of the machines (inserters, assemblers, furnaces, steam engines, labs, etc.).
* Sound effects for car and trains.
=== Changes ===
* Disabled loading of saves before 0.6.0 version (You can use 0.6.4 to load any old saves and re-save them).

{{:Diesel locomotive/infobox}}

The '''Diesel locomotive''' is the engine for movement of [[Railway network|trains]] over [[Railway network#Tracks|track]]. Trains are useful for moving large amounts of items over large distances.

Locomotives are also good vehicles for the player to reach fixed destinations, as they are considerably faster than the [[Car]] or [[Tank]]. Naturally they do not have the same freedom of movement, however, as they are confined to the track.

Locomotives are [[burner devices]] and require [[fuel]] to run. Despite the name, they can take any fuel, not just oil-derived types.

While Locomotives can be assembled by hand, the [[Engine unit]]s for it require automated construction to build, so it cannot be built from raw materials by hand.

== Achievements ==
{{Main|Achievements}}
Diesel locomotives are directly connected to the following achievements:
; Getting on track
: Build a diesel locomotive.
; Getting on track like a pro
: Build a diesel locomotive within first 1 hour and 30 minutes of the game.
; Watch your step
: Get killed by moving locomotive.

== Driving Controls ==
''These are the default bindings. They can be changed in the Options menu.''
{|
|Enter/Exit
|{{Keybinding|enter}}
|-
|Accelerate
|{{Keybinding|W}}

|-
|Connect/Disconnect rolling stock
|{{Keybinding|G}}
|}

Note that while you can enter a train at any point, you must enter a Locomotive to drive the train manually (and automatic mode must be off).

== Connecting/Disconnecting a Locomotive ==
To connect Locomotives or [[Cargo wagon]]s to each other, either place the cars next to each other on the track (there will be an outlined green connection), or, to connect an already existing disconnected car, drive the Locomotive near the car and press G by default. To disconnect the last car in a train, press V by default.

== Defense ==
Locomotives are a priority target of [[Enemies]], so places where trains can stop should be [[Defense|defended]]. Locomotives in transit can usually crash through everything in the way (including [[Biter]]s, [[Tank]]s, and the Player) so defense in transit is less important. However, enemies can attack and destroy rails, potentially stopping the train.

[[Construction robot]]s are a good way to automatically repair damage at train stations.

Locomotives are also good vehicles for the player to reach fixed destinations, as they are considerably faster than the [[Car]] or [[Tank]]. Naturally they do not have the same freedom of movement, however, as they are confined to the track.

Locomotives are [[burner devices]] and require [[fuel]] to run. Despite the name, they can take any fuel, not just oil-derived types.

While Locomotives can be assembled by hand, the [[Engine unit]]s for it require automated construction to build, so it cannot be built from raw materials by hand.

== Achievements ==
{{Main|Achievements}}
Diesel locomotives are directly connected to the following achievements:
; Getting on track
: Build a diesel locomotive.
; Getting on track like a pro
: Build a diesel locomotive within first 1 hour and 30 minutes of the game.
; Watch your step
: Get killed by moving locomotive.

== Driving Controls ==
''These are the default bindings. They can be changed in the Options menu.''
{|
|Enter/Exit
|Enter
|-
|Accelerate
|{{Keybinding|W}}
|-
|Decelerate/Reverse
|{{Keybinding|S}}
|-
|Pick which fork to take at junction
|{{Keybinding|A}},{{Keybinding|D}}
|-
|Connect/Disconnect rolling stock
|{{Keybinding|G}}
|}

Note that while you can enter a train at any point, you must enter a Locomotive to drive the train manually (and automatic mode must be off).

== Connecting/Disconnecting a Locomotive ==
To connect Locomotives or [[Cargo wagon]]s to each other, either place the cars next to each other on the track (there will be an outlined green connection), or, to connect an already existing disconnected car, drive the Locomotive near the car and press G by default. To disconnect the last car in a train, press V by default.

== Defense ==
Locomotives are a priority target of [[Enemies]], so places where trains can stop should be [[Defense|defended]]. Locomotives in transit can usually crash through everything in the way (including [[Biter]]s, [[Tank]]s, and the Player) so defense in transit is less important. However, enemies can attack and destroy rails, potentially stopping the train.

[[Construction robot]]s are a good way to automatically repair damage at train stations.

LowBattery: /* Constant combinator */

== Foreword ==

This page provides examples of simple circuit network designs and some not so simple designs that others can use, combine and modify. They are designed to be as easy to understand as possible.

== Oil Setups ==
[[File:LgtOilCracking.png|left|400x400px]]
=== Light Oil Cracking ===
* This circuit provides balanced light oil and petroleum gas production by cracking excess light oil into gas.
* The [[Small pump]] is connected to the [[Storage tank]] by a [[Red wire]].
* The [[small pump]] has an enabled condition set to '''Light Oil > 2000'''.
{{clear}}

[[File:HvyOilCracking.png|left|400x400px]]

=== Heavy Oil Cracking ===
* This circuit extends on the previous circuit by adding optional heavy oil cracking to provide lubricant etc.
* The [[Small pump]] has an enabled condition set to '''Heavy oil > 2000'''.
{{clear}}

[[file:BalancedPlasticSulfur.png|left|400x400px]]

=== Petroleum split evenly between plastic and sulphuric acid ===
* This circuit buffers gas in the tank until there is at least 100, then it lets the tank drain until there is less than 50 and the cycle repeats.
* It has a few elements that work together to do achieve this.
* Firstly the [[Small pump]] is connected to the [[Wooden chest]] by a [[Red wire]] and the enabled condition on the [[Small pump]] is set to '''Raw wood > 0'''.
* Both of the [[Basic inserter]]s are connected to the [[Storage tank]] by [[Red wire]]s.
* The enabled condition on the left inserter is '''Petroleum gas > 100'''
* The enabled condition on the right inserter is '''Petroleum gas < 50'''.
* You will need to insert a single "Raw wood" into the chest to make it all work.
<br />
* It is also possible to do this with [[decider combinator]]s instead of the inserters, belt and the Wood chest or even just belts.
{{clear}}

== Lights ==
[[File:ConditionalLights.png|left|400x400px]]
=== Conditional Lights ===
* In this circuit we connect a series of [[lamp]]s to a [[Storage Tank]].
* By setting different conditions on each [[lamp]] we can build an indicator strip.
* The Enabled condition of the first [[lamp]] is '''Petroleum gas > 100'''.
* The others light up when gas is greater than 200, 300, 400 and 500 respectively.
{{clear}}

[[File:ColoredLights.png|left|400x400px]]

=== Colored Lights ===
* To light a [[lamp]] with a color rather than white, you need to do two things.
* 1. Send a colored signal to the lamp
* 2. Select the "Use colors" check box on the lamp.
* In this case we want to convert a Petroleum gas signal into a pink signal.
* We can do this with an [[Arithmetic combinator]], setting the input to Petroleum Gas + 0 (the constant 0 not the signal 0) and set the output to the Pink signal (on the bottom row of the last tab of signals.)
{{clear}}

== Misc ==
[[file:MulitipleChestsAndPoles.png|left|400x400px]]
=== Multiple Storages ===
* If you connect multiple chests to a pole, the pole displays the sum of items in all the chests.
* This also works with [[Storage tank]]s and [[roboport]]s.
{{clear}}

[[File:ConstantComb.png|left|400x400px]]

=== Constant combinator ===
* With a [[constant combinator]] you can generate any signals you may need.
* In this example we have generated a signal of 50 Laser turrets and 200 Piercing round magazine.
* Constant combinators are not of much use on their own but we shall use them later.
{{clear}}

[[File:LogicGates.png|left|400x400px]]

=== Logic gates ===
* In each case the two inputs can be connected with the same color wire or different colors. The inputs are powered by two [[Constant combinator]]s each of them output an A signal with value 1 for true and nothing or false.
* You can use [[Decider combinator]]s to make all of the common logic gates.
* The output for each should be set to 1 and the signal of your choice.
* Use the following settings to create different gates:
{{clear}}

NOT A=0
NOR A=0
NAND A<2
XOR A=1
AND A=2
OR A>0

{{clear}}

[[File:ThisASign.png|left|400x400px]]

=== Constant combinator signs ===
* You can use [[Constant combinator]]s to make signs, just set the letter signals in the combinator, each combinator can display 2 characters side by side.
{{clear}}

[[File:MemoryCell.png|left|400x400px]]

=== Memory Cell / Counter ===
* Basic memory cell that counts all the items moved by the inserter
* The [[Fast inserter]] is connected to '''BOTH''' ends of the arithmetic combinator.

* If the [[Fast inserter]] hasn't picked anything up this tick the input to the Arithmetic combinator is the same as and output and hence the values are persisted.
* When the [[Fast inserter]] does pick something up its value is added to the output from the previous tick thus incrementing that item.
{{clear}}

[[File:BeltCache.png|left|400x400px]]

=== Automatic Belt-Cache ===
* Some intermediate products are huge in demand during peak-production only. To bypass the need of providing a huge amount of factories in order to cover that peaks, a cache-unit can be used. The unit stores items, while the belt has backed up (so theres obviously no current demand downstream) and releases items as soon as the belt gets too empty.
* The blue area are 3 parts of Express belts. According to the wiki, each belt can hold up to 7.11 items. This means the feeding fast belt can not provide 7.11 items for the express belts as long as the belt is moving. (And while the belt is moving, we don't want to cache items, but let regular production run, or even release items from the cache.)
* This means, once the counters on the two express belts are 7.11 each, the belt has backed up, so we can start "caching" items into our storage array.
* For this purpose, the counters are connected to the arithmetic combinator (A) which multiples the input (*100) into green signals. So, if the belt has backed up, B shows ">1422" green signals.
* This is the activation condition for the Belt (C), which will redirect the input tp the storage array.
* Since items should only be released if the belt starts to clear, the counter (D) is evaluated by the belt (E) which is only activated, if item-count on (D) is smaller than 6 (this number has to be adjusted to personal needs, when the cache should become "active" and release items)
* The layout can be extended to cache whatever amount of items is required. (Some balancing for the release-method would be required ofc.)

{{clear}}

== Inserters ==
[[File:LimitItemsPlacedIntoAChest.png|left|400x400px]]
=== Limit items placed into a chest ===
* The [[Basic inserter]] is connected to the [[Wooden chest]] using a [[Red wire]].
* The inserter's enabled condition is '''Advanced Circuit < 10'''.
* In reality this means the inserter may place more than 10 Advanced circuits in the chest because it could pick up-to 3 at once.
* This effect can be even greater with Stack inserters because of their large carrying capacity.
* This technique still gives far greater control than limiting the inventory on the chest.
{{clear}}

[[File:SmartOutpostUnloader.png|left|400x400px]]
=== Keeping outpost stocked with specified items ===
* This circuit keeps a [[Storage chest]] at an outpost stocked with customized levels of different items.
* For example you could keep an outpost stocked with 50 laser turrets and 200 piercing magazine rounds but not have to worry about it being over filled.
* The [[storage chest]] is attached to the input of the [[Arithmetic combinator]] (left side in the picture) with a [[Red wire]].
* Another couple of [[Red wire]]s join the output of the [[Arithmetic combinator]] (right side) to the [[constant combinator]] and to the [[stack filter inserter]].
* The [[Arithmetic combinator]] '''multiples''' each input value (from the storage chest) by '''-1'''.
* Finally the filter stack inserter's mode of operation is set to '''Set filters'''.
<br />
* So the input to the [[stack filter inserter]] is '''<Constant combinator> - <Storage chest contents>''' and the filter is set to filter the item of greatest demand.
{{clear}}

[[File:SolarAccumalatorBalancer.png|left|400x400px]]

=== Balanced Solar panel / Accumulator Production ===
* This circuit balances production of [[Solar panel]]s and [[Accumulator]]s to a desired ratio in my case 24:20.
* The first [[Arithmetic combinator]] takes the number of accumulators in the chest and '''multiples''' it by '''24'''.
* The second [[Arithmetic combinator]] takes the output of the first combinator and '''divides''' it by '''20'''.
* This gives us the number of accumulators that we can directly compare to the number of Solar panels in both inserters.
* If the number of accumulators is greater we enable the Solar panels inserter, if the number of Solar panels is greater we enable the accumulators inserter.
* However, if they are equal, neither machine does anything. So we add a single accumulator to one of the inserters using a constant combinator and a wire of the other color, therefore breaking the deadlock.
{{clear}}

== Sushi Belts ==
[[File:SushiScience1.png|left|400x400px]]
=== Reading Belt Design ===
* Six belts in a row are connected with Red wire and set to '''Read belts contents''' and '''Hold'''
* This [[Red wire]] is then connected to the inserters that insert onto the belt.
* Read hand contents is unselected for all inserters.
* Mode of operation is set to '''Enable/Disable''' on all inserters.
* The first inserter is enabled when '''Science pack 1 = 0'''
* The other inserters are set similarly for the other science packs.
{{clear}}

[[File:SushiScience2.png|left]|400x400px]]
=== Memory Cell Design ===
* This circuit counts the number of items of each type on a looping belt by counting the numbers that are added and removed from the belt by inserters.
* Each inserter that takes items off the belt is connected together with Red wire and each of these inserters is set to '''Mode of operation none, Read hand content selected''' and '''Hand read mode pulse'''.
* These inserters are connected to the input of the left arithmetic combinator.
* The left [[Arithmetic combinator]] multiples '''each''' input by '''-1''' and outputs it to '''each'''.
* The right [[Arithmetic combinator]] is a '''memory cell''' as above.
* The memory cell's input is connected to the inserters that are placing items on the belt and the output of the left [[Arithmetic combinator]].
* The inserters that place items onto the belt have an enabled condition that is based on the number of items on the belt.
{{clear}}

== Splitters ==
[[file:CondSplitter.png|left|400x400px]]
=== Conditional splitter ===
* This is the most simple circuit you can have for "controlling" a splitter.
* A signal X=1 is transmitted from off screen when the items need to be sent down the belt.
* The belt on the left is enabled when X=1.
* The belt on the right is enabled when X=0.
* The two belts are wired together and to a pole.
{{clear}}

[[File:PrioritySplitter.png|left|400x400px]]
=== Priority Splitter ===
* This circuit prioritizes items to the belt going of the screen to the left but will send items straight on if the belt to the left is backed up.
* Its not perfect and will leak some items but its good enough for most applications.
* The balancer means it will work even if the supply or demand is uneven.
<br />
* It is critical that the belts are setup as in this picture otherwise it may not work.
{{clear}}

== Power ==
[[File:SteamBackup.png|left|400x400px]]
=== Backup steam power ===
* The [[steam engine]]s are not directly connected to the power network. They are connected to the power network through a [[Power switch]].
* The [[power switch]] is connected to one of the [[accumulator]]s in the main network.
* The [[power switch]] turns on when A < 10. That is when the [[accumulator]]s are less than 10% full.
{{clear}}

== Latches ==
[[File:SRLatch.png|left|400x400px]]
=== SR latch ===
* This should be familiar to anyone with any background in electronics.
* The signal is set and reset with the [[constant combinator]]s on the left by setting an A=1 signal.
* The latch "remembers" which one was last set and the light stays on until another signal is received.
{{clear}}

[[File:SRlatchinaction.png|left|400x400px]]
=== Usage of SR latch ===
* Here is an example of how you could use an SR latch.
* The two extra [[Decider combinator]]s provide the set and reset conditions.
* Petroleum gas < 50 and petroleum gas > 100.
{{clear}}

[[File:BeltLatch.png|left|400x400px]]
=== Belt only latch ===
* This is the most compact latch I am aware of.
* To make it work you need to place '''3''' raw wood on the inside lane of the belt.
* I believe it will have higher latency than the combinator version but in most situations you will not notice the difference.
{{clear}}

== Displays ==
[[File:5digitDisplay.png|left|400x400px]]
=== Numerical Display ===
* Each digit is driven by its own [[Green wire]], that wire holds 15 signals one for each lamp used in the digit.
* [[Constant combinator]]s are used to define which lamp should light up for each value.
* Blueprint string including decoder [https://www.dropbox.com/s/5o13xuwthalzzfe/Brain2.txt?dl=0]
{{clear}}

[[File:BWDisplay.png|left|400x400px]]

=== Black and White Grid Display ===
* Each row has its own [[Red wire]] connection and within that row each light has a numbered signal 0-9.
* We turn each light on by just setting or clearing the relevant signal.
{{clear}}

[[File:MultiColoredDisplay.png|left|400x400px]]
=== Multicolor Display by DaveMcW ===
* To understand how this works, you first need to understand how color lights choose which color to light up when there are multiple colored signals.
* The [[lamp]] will light up with the colored signal that is greater than zero and earliest in this list: Red, Green, Blue, Yellow, Pink, Cyan, White.
* We have a [[Red wire]] per column, that wire has each of the colored signals on it at different values and a numbered signal for each row.
* There is a [[Arithmetic combinator]] for each cell that subtracts the "row" value from each of the colored signals.
* And this enables us to choose the color for each cell.
* Simple!

LowBattery: /* See also */

{{Languages}}
Modules are items used to enhance existing buildings' capabilities. They are expensive, require appropriate research and are produced slowly, but can eventually greatly improve the efficiency of a factory. In addition to improving the efficiency of the factory, modules are also used in many late- and endgame recipes such as modular armor and its equipment.

Quick lookup sheet:
*If you want more products per second, use a speed module.
*If you want more products per input resource, use a productivity module.
*If you want more products per watt of energy, use an efficiency module.

== Types of modules ==

There are three types of modules in factorio, each with 3 tiers of effect. Crafting higher tiers requires lower tiers to be made.

=== Speed Module ===
Used in many [[Modular armor]] recipes. Increases the speed and energy consumption of a machine.

{| class="wikitable"
|-
! Module !! Speed bonus !! [[Electric system|Energy]] consumption
|-
| {{icon|speed-module||Speed module 1}} || +20% || +50%
|-
| {{icon|speed-module-2||Speed module 2}} || +30% || +60%
|-
| {{icon|speed-module-3||Speed module 3}} || +50% || +70%
|-
|}

Advantages & Disadvantages:

* <span style="color:#00BB00"> Increases speed of machine. </span>
* <span style="color:#FF0000"> Increases energy use per cycle. </span>
** <span style="color:#FF0000"> Increases pollution generated due to energy consumption being higher. </span>

----

=== Productivity Module ===

{| class="wikitable"
|-
! Module !! Productivity !! [[Electric system|Energy]]<br \> consumption !! Speed !! [[Pollution]]<br/> multiplier
|-
| {{icon|productivity-module||Productivity module 1}} || +4% || +40% || -15% || +5%
|-
| {{icon|productivity-module-2||Productivity module 2}} || +6% || +60% || -15% || +7.5%
|-
| {{icon|productivity-module-3||Productivity module 3}} || +10% || +80% || -15% || +10%
|-
|}

Productivity modules add a second purple "production bar" at item producing buildings and labs. It fills at the speed of (production - 100%). When it reaches 100%, an extra item (or items, in recipes that result in more than one) is produced.

'''Productivity modules can only be used to make [[Items#Intermediate products|intermediate products]]. These are products that cannot directly be placed, but are used in other recipes. Examples include circuits, science packs and engine units.'''

Advantages & Disadvantages:

* <span style="color:#00BB00"> Creates an additional free item occasionally. </span>
* <span style="color:#FF0000"> Increases energy use per cycle. </span>
* <span style="color:#FF0000"> Increases pollution generated. </span>
* <span style="color:#FF0000"> Slows the machine. </span>

----

=== Efficiency Module ===
The efficiency module reduces the cost of electricity to run the machine. Note that minimal energy usage is 20% of base energy usage, to prevent the machine's running being free.

{| class="wikitable"
|-
! Module!! [[Electric system|Energy]] consumption
|-
| {{icon|effectivity-module||Efficiency module 1}} || -30%
|-
| {{icon|effectivity-module-2||Efficiency module 2}} || -40%
|-
| {{icon|effectivity-module-3||Efficiency module 3}} || -50%
|-
|}

Advantages & Disadvantages:

* <span style="color:#00BB00"> Reduces energy cost per cycle. </span>
* No downsides

== Usage tips ==

More modules of the same type in one device will give diminishing returns, as the negative attributes, such as bonus power consumption, will pile up and nullify the good effect. Because of that, it is generally more effective to add '''efficiency modules with speed and/or productivity modules''' to get more bonuses over the crafting cascade (assembly lines), especially when assembling machines are part of logistics network. This applies to situations where resources are plentiful but finite.

This is has been [http://www.factorioforums.com/forum/viewtopic.php?f=5&t=5705 calculated through in this discussion].

Filling the device with '''speed modules''' is useful when a resource is infinite but the amount of resource pools is low. The best example would be '''oil deposits'''. Another good place to use speed modules would be for assembly machines which make products that take a long time to make. Examples would be engine units. Using speed modules allows for compaction of setups, because one machine can provide materials to more consumers than normal.

Filling devices with '''productivity modules''' is recommended when resources are scarce. Example would be '''alien artifact''' processing. It will take longer and more energy, but the overall produced products will be higher.

Filling devices with '''efficiency modules''' is recommended for electric furnaces as these use a lot of power. Efficiency modules also completely lack downsides, so filling all unnecessary module slots with Efficiency modules if possible is recommended.

Modules are also able to control [[Pollution]], as '''pollution depends also on [[Electric system|Energy]] usage'''. So reducing a machines energy usage by 40% with a efficiency module 2 will also reduce its pollution by 40%. Beware as this also works vice versa!

=== Productivity modules and speed modules ===

While the effects are biggest with the version 3 chips, this stacking effect is also very noticeable with version 2 chips. Or if the final 10% productivity doesn't matter that much, consider putting a speed chip in there too.

=== Examples of usage ===
[[Electric furnace]]s are huge power hogs at 180 kW per furnace. 1 basic efficiency module reduces it by 54 kW (-30%) - almost a [[Solar panel]] worth of power.

[[Electric mining drill]]s create 9 units of [[Pollution]] with no efficiency modules and 1.8 with 3 basic ones.

Same [[Electric mining drill]] with 3 Productivity modules 3 would create 76.5 units of [[Pollution]].

LowBattery:

Hello, you have reached the user page of LowBattery. I have accumulated about thirty hours of Factorio gameplay as of the writing of this page (March 2017). My plan is to continue exploring of the planet, assimilate the local fauna, and launch many trains into space. Thank you for visiting and have a nice day.

''This article is about the battery intermediate product. For the modular armor equipment, see [[Battery MK1]] and [[Battery MK2]]. For the technology, see [[Battery (research)]].''

The '''Battery''' is an intermediate product used in several key recipes, including [[science pack 3]] which is required for advanced research, and the [[flying robot frame]], which is required to build [[logistic robot|logistic]] and [[construction robot]]s.

Batteries are also a crucial component of powering your base using [[solar panel|solar power]] because of their use in crafting [[Accumulator]]s.

Accumulator

2017-03-30T17:17:59Z

LowBattery:

{{Languages}}
{{:Accumulator/infobox}}

The accumulator stores a limited amount of energy when available production exceeds demand, and releases it in the opposite case. The accumulator can store up to 5 MJ of energy. Its charge/discharge rate is 300 kW maximum.

== Notes ==
* 5MJ of stored energy takes approximately 17s to fully charge/discharge at the maximum rate of 300kW. Read [[Game-second]] for further time related calculations.
* It takes 25 accumulators (125MJ) to maintain 1MW through the night.
* When discharged above maximum speed by multiple unconnected poles, energy will not be distributed equally (some loads may get 100% demand, others 0%)
* May be used to provide a limited amount of power (multiples of maximum charge rate) to a section of the grid.
* Produces light when charging and discharging.
* Can act as an emergency backup for your base in case of blackout, until main power supply is restored.
* Can be used to power the base at night if it relies heavily on [[solar panel]]s.
* Can act to satisfy surging demands of certain loads. If the power usage of one device exceeds production for a few seconds or so, the accumulator can provide power to the grid until said device shuts down or requires a lesser power requirement.

== Circuit Network ==

If connected to a [[circuit network]], an accumulator will output its level of charge, as an integer from 0 to 100, to a specified signal.

== Other uses ==

=== Isolation of Power Networks ===

[[Electric network#Storage|Accumulator]]s can be used to isolate two separate power networks, which has a number of uses. Since accumulators have a lower delivery priority than any other entity, this guarantees that they only receive energy when you have enough left over after powering all other entities in a network. At the same time, accumulators can also be used to deliver energy in another electrical network, and can charge and discharge at the same time. Consider the following example:

[[File:Accumulator_Network_Isolation.png]]

The two power networks A and B are not directly connected to each other: They are connected only through the accumulators, which are shared by both networks. This is accomplished by setting up electric poles for each network connected to the accumulators, then ensuring the sets of poles are not connected to each other (which can be done by crafting a copper wire then dragging it between two connected poles to sever the connection, exactly as is done for disconnecting circuit wires).

In the above example:

* The accumulators will only charge if extra power is being produced by network A or B.
* The accumulators will discharge as needed into either network if one is not producing enough power.
* Since the maximum input/output rate of an accumulator is 300 kW, power flow between the two networks will be limited to 300 kW times the number of accumulators (1.5 MW in the example).
* Note that this isolation is bidirectional: Either network can charge the accumulators, and the accumulators can discharge into either network.

This technique can be used whenever this type of isolation is desired.

==== Reduction of Energy Consumption in Critical Situations ====

In particular, one good use for the above technique is to limit electricity consumption in low power situations by isolating non-critical parts of your factory (such as [[Radar]], [[Lab]]s, [[Electric furnace]]s, [[Electric mining drill|electric miner]]s, [[Beacon]]s, etc.) from critical parts (such as lasers, ammo production, or whatever your priorities are).

To do this, place your main generators and critical components on one network and place your non-critical components on another network, isolating the two as above. Now, two things will happen:

* Power will ''only'' flow to the non-critical network when you are generating a surplus on the main network, and
* The rate will always be limited to 300 kW per accumulator.

Because the accumulators will only receive power if you have a surplus on the main network, this will in effect deactivate the low-priority network when electricity is in short supply. This will also limit power consumption of the low priority network if its usage becomes high, for example if you have two factories on a low priority network and usually only one of them runs at a time, if both happen to run they won't consume more than the total limit, they'll just slow down.

Essentially you are saying "only deliver power to these systems if I have enough to spare, and even then don't exceed this delivery rate".

In general this is a technique which works well when you've just researched accumulators and solar panels, but don't have enough resources to build big solar farms and accumulator farms yet.

Circuit network

2017-03-30T16:37:30Z

LowBattery: /* Physical network structure */

{{Languages}}
'''Circuit networks''' are built using red or green wire, and enable the control of receivers, based upon information broadcast onto the network by connected senders. Most senders are storage devices, and broadcast their information onto a specific channel, based on the item or liquid the storage device contains. Each circuit network contains a channel for every kind of item, as well as 45 extra [[Virtual signals]] which act as user-definable channels. 'Everything', 'Anything' and 'Each' are also available wildcards.

[[File:InnerOfGreenCable.jpg|right|thumb|400px|A player drawn visualization of the interior of a circuit cable.]]

== Usage ==
=== Send Information ===
Senders broadcast the amount of [[Items]] or [[Liquids system|Fluids]] they contain or other data definable by the player. Each amount is broadcast as a numeric value on a 'channel' corresponding to the item they contain. For example, a Storage Tank containing 1000 Crude Oil will broadcast 1000 on the Crude Oil channel.

Multiple broadcasts of the same item or fluid are additive: If there are two connected Storage Tanks with 1000 Crude Oil each, the value of the Crude Oil channel within the network will be 2000.

Wires which are connected together by a junction will pass their signals to the other wires of the same color. For example, if two red wires are connected to the same combinator input, each wire receives the content from the other. This can result in feedback if care is not taken; see Feedback (under Arithmetic Combinator, below) for discussion.

=== Control Devices ===
[[File:smart_inserter.png|thumb|250px|Example condition: "Work only if the count of Iron plates is lower than the count of Steel plates." Remember to set the filter as well.]]
Receivers can use broadcast information, in most cases to enable/disable the device.

They can either compare results between different channels, or compare a channel to a specific value. The pictured inserter works if the count of [[Iron plate|Iron plates]] is lower than the count of [[Steel plate|Steel plates]].

Receiving devices sum all signals from each wire connected to them, even red and green wires. For example, if an inserter is connected to a red wire carrying a signal for 20 iron plates, a green wire with 10 copper plates and another green wire with 5 iron plates, the input signal set for that receiver will be 25 iron plates and 10 copper plates.

== Devices ==

Since version 0.13 each entity connectable to one of the networks has icons in its top right corner. By clicking the left icon, you have access to the circuit network settings (if one is connected), by clicking the right icon, you have access to the logistic network settings, if one is reachable. There can be set conditions for both circuit (signals of red and green wires are summed) and logistic network, which will together act as a logical AND.

|}

== Physical network structure ==
A circuit network consists only of those devices connected together with the same color wire. Wire can be strung directly from device to device, or across any intervening power poles. Wire length is limited by its previous connection.

Note that each connected set of wires forms a separate network. For example, it's entirely possible to have four red-wire networks and three green-wire networks. If red and green wires happen to touch the same power pole or device, the red and green networks will remain separate and will not link up . However, two red cables or two green cables will link if they touch. Use different colored cables to separate networks in close proximity.

* To connect wires or cables to a power pole, simply click on one entity, then on the base of the power pole.
* To erase a wire or cable connection, place the same color wire over an existing connection. You don't get the wire/cable back.
* To remove '''all''' connections from a power pole, shift-click on the pole. The first shift-click will remove all electrical connections, and the second will remove all red and green wires. You don't get the wires back.
* When connecting to a [[Arithmetic Combinator]] or [[Decider Combinator]], take care to connect the wire to the correct input or output side. Use ALT-Key-Mode to see direction of combinator.
* Hovering the mouse cursor over an item will highlight all wires which form the network of the item.
* Hovering the mouse cursor over a power pole which is part of a network will display the signals on its network. Some items like combinators will also display their input and output signals when hovered over.

== Combinators ==
Combinators can function as both receiving and sending devices and allow more advanced functions to be used on a circuit network.

*The [[Constant Combinator]] broadcasts up to 15 values on any of the channels for whatever networks it is connected to. (You cannot currently specify whether a value should be on the red or green channel; if you need different values, use two combinators, one for each color wire.) You can use any item channel or any of the [[Automatic control/Virtual signals|virtual signal]] channels.
**Note that using two of the 15 slots to broadcast values on the '''same''' channel is the same as broadcasting the sum of the two values from one slot.

*The [[Arithmetic Combinator]] performs arithmetic operations on input values and broadcasts the result to the specified output channel. The input and output channels can be any item channel or any of the virtual signal channels.
** Connecting: The Arithmetic Combinator connects to a red or green network on its '''input''' side (the terminals are set into the main body and look like spark plugs) and performs an arithmetic calculation which is broadcast into the specified channel on its '''output''' side (the output wires appear to stretch out a bit from the body of the device).
** Feedback: Note that the input network and the output network '''are not the same network'''. Connecting the output network back to the input network will result in a feedback loop. For example, adding 1 to the value for Copper Plates and broadcasting it as Copper Plates is an action that results in an infinite loop if output is connected back to input. The value for Copper Plates will rapidly (but not instantly) shoot upward. (Fun fact: The rate at which it climbs is the current tick rate) This technique can be combined with Decider Combinator logic to make electronic clocks, gates, and other systems; see [[Combinator Tutorial]] for advanced techniques.
** Each: This combinator can use the 'Each' signal for both input and output, in which case '''all''' non-zero input channels will have the combinator's operation performed and broadcast on the output side. Having Each signals for input and output and using a non-changing operation (like adding zero) is equivalent to having a 'one-way' wire; all the information from the input network is copied to the output network, but the reverse is not true.
**Multi-network: The Arithmetic Combinator can be joined to both red and green networks on the input side and will sum their inputs.

*The [[Decider Combinator]] functions much like an Arithmetic Combinator, but is designed to compare values. Essentially, it is a conditional. In terms of Connecting, Feedback, and the Each signal it functions as specified above. In addition, it can handle the Everything and Anything signals, and performs more complex functions than summing when attached to multiple networks. See the [[Decider Combinator]] page for more details on how to use this.

== Logistic Network ==
The Logistic network used by [[Logistic robot|Logistic robots]] is essentially a third network (a wireless one), along with the green and red wired network. The Logistic Network is based on proximity to a central [[Roboport]].

Some devices can also be connected to the logistic network. If a device has conditions set for circuit and for logistic network, it will become activated if both conditions are true.

Circuit network

2017-03-30T16:31:56Z

LowBattery: /* Senders */

{{Languages}}
'''Circuit networks''' are built using red or green wire, and enable the control of receivers, based upon information broadcast onto the network by connected senders. Most senders are storage devices, and broadcast their information onto a specific channel, based on the item or liquid the storage device contains. Each circuit network contains a channel for every kind of item, as well as 45 extra [[Virtual signals]] which act as user-definable channels. 'Everything', 'Anything' and 'Each' are also available wildcards.

[[File:InnerOfGreenCable.jpg|right|thumb|400px|A player drawn visualization of the interior of a circuit cable.]]

== Usage ==
=== Send Information ===
Senders broadcast the amount of [[Items]] or [[Liquids system|Fluids]] they contain or other data definable by the player. Each amount is broadcast as a numeric value on a 'channel' corresponding to the item they contain. For example, a Storage Tank containing 1000 Crude Oil will broadcast 1000 on the Crude Oil channel.

Multiple broadcasts of the same item or fluid are additive: If there are two connected Storage Tanks with 1000 Crude Oil each, the value of the Crude Oil channel within the network will be 2000.

Wires which are connected together by a junction will pass their signals to the other wires of the same color. For example, if two red wires are connected to the same combinator input, each wire receives the content from the other. This can result in feedback if care is not taken; see Feedback (under Arithmetic Combinator, below) for discussion.

=== Control Devices ===
[[File:smart_inserter.png|thumb|250px|Example condition: "Work only if the count of Iron plates is lower than the count of Steel plates." Remember to set the filter as well.]]
Receivers can use broadcast information, in most cases to enable/disable the device.

They can either compare results between different channels, or compare a channel to a specific value. The pictured inserter works if the count of [[Iron plate|Iron plates]] is lower than the count of [[Steel plate|Steel plates]].

Receiving devices sum all signals from each wire connected to them, even red and green wires. For example, if an inserter is connected to a red wire carrying a signal for 20 iron plates, a green wire with 10 copper plates and another green wire with 5 iron plates, the input signal set for that receiver will be 25 iron plates and 10 copper plates.

== Devices ==

Since version 0.13 each entity connectable to one of the networks has icons in its top right corner. By clicking the left icon, you have access to the circuit network settings (if one is connected), by clicking the right icon, you have access to the logistic network settings, if one is reachable. There can be set conditions for both circuit (signals of red and green wires are summed) and logistic network, which will together act as a logical AND.

|}

== Physical network structure ==
A circuit network consists only of those devices connected together with the same color wire. Wire can be strung directly from device to device, or across any intervening power poles. Wire length is limited by it's previous connection.

Note that each connected set of wires forms a separate network. For example, it's entirely possible to have four red-wire networks and three green-wire networks. Red and green networks will remain separate and do not link up if red and green wires happen to touch the same power pole or device. However, two red cables or green cables will link if they touch. Keep networks in close proximity separate by using different colored cables.

* To connect wires or cables to a power pole, simply click on one entity, then on the base of the power pole.
* To erase a wire or cable connection, place the same color wire over an existing connection. You don't get the wire/cable back.
* To remove '''all''' connections from a power pole, shift-click on the pole. The first shift-click will remove all electrical connections, and the second will remove all red and green wires. You don't get the wires back.
* When connecting to a [[Arithmetic Combinator]] or [[Decider Combinator]], take care to connect the wire to the correct input or output side. Use ALT-Key-Mode to see direction of combinator.
* Hovering the mouse cursor over an item will highlight all wires which form the network of the item.
* Hovering the mouse cursor over a power pole which is part of a network will display the signals on its network. Some items like combinators will also display their input and output signals when hovered over.

== Combinators ==
Combinators can function as both receiving and sending devices and allow more advanced functions to be used on a circuit network.

*The [[Constant Combinator]] broadcasts up to 15 values on any of the channels for whatever networks it is connected to. (You cannot currently specify whether a value should be on the red or green channel; if you need different values, use two combinators, one for each color wire.) You can use any item channel or any of the [[Automatic control/Virtual signals|virtual signal]] channels.
**Note that using two of the 15 slots to broadcast values on the '''same''' channel is the same as broadcasting the sum of the two values from one slot.

*The [[Arithmetic Combinator]] performs arithmetic operations on input values and broadcasts the result to the specified output channel. The input and output channels can be any item channel or any of the virtual signal channels.
** Connecting: The Arithmetic Combinator connects to a red or green network on its '''input''' side (the terminals are set into the main body and look like spark plugs) and performs an arithmetic calculation which is broadcast into the specified channel on its '''output''' side (the output wires appear to stretch out a bit from the body of the device).
** Feedback: Note that the input network and the output network '''are not the same network'''. Connecting the output network back to the input network will result in a feedback loop. For example, adding 1 to the value for Copper Plates and broadcasting it as Copper Plates is an action that results in an infinite loop if output is connected back to input. The value for Copper Plates will rapidly (but not instantly) shoot upward. (Fun fact: The rate at which it climbs is the current tick rate) This technique can be combined with Decider Combinator logic to make electronic clocks, gates, and other systems; see [[Combinator Tutorial]] for advanced techniques.
** Each: This combinator can use the 'Each' signal for both input and output, in which case '''all''' non-zero input channels will have the combinator's operation performed and broadcast on the output side. Having Each signals for input and output and using a non-changing operation (like adding zero) is equivalent to having a 'one-way' wire; all the information from the input network is copied to the output network, but the reverse is not true.
**Multi-network: The Arithmetic Combinator can be joined to both red and green networks on the input side and will sum their inputs.

*The [[Decider Combinator]] functions much like an Arithmetic Combinator, but is designed to compare values. Essentially, it is a conditional. In terms of Connecting, Feedback, and the Each signal it functions as specified above. In addition, it can handle the Everything and Anything signals, and performs more complex functions than summing when attached to multiple networks. See the [[Decider Combinator]] page for more details on how to use this.

== Logistic Network ==
The Logistic network used by [[Logistic robot|Logistic robots]] is essentially a third network (a wireless one), along with the green and red wired network. The Logistic Network is based on proximity to a central [[Roboport]].

Some devices can also be connected to the logistic network. If a device has conditions set for circuit and for logistic network, it will become activated if both conditions are true.

See [[Logistic network]] and [[Roboport]] for more information.

Logistic network

2017-03-30T16:11:45Z

LowBattery: /* Priorities of robots */

{{Languages}}

[[File:RoboTrainStation.gif|thumb|632x562px|right|''This gif shows how robots can load or unload chests in a train station. The top track is for loading; and there are [[Requester chest]]s on both sides. The requested items are then filled into the wagons. The second track is the unloading track, the delivered items are filled into [[Active Provider chest]]s and then put into the [[Storage chest]]s at the very top and at the center. At the bottom the incoming ores from both sides are moved into [[Active Provider chest]]s; and then put into the requester chests at the top track.'' Logistics robots are ideal in train stations, since very high item throughput on a short distance is needed.]]

A [[Logistic network]] (LogNet) is a series of different chests and [[Logistic robot]]s all covered by one or more [[Roboport]]s.

Depending on the type and configuration of the chests and area of the [[Robotic network]] the robots will transport items between these chests as a power-hungry alternative to moving items manually, or by [[Transport network|belts]] or [[Railway network]]. However, robots offer much higher mobility, since they can fly over obstacles.

The player character can also act as [[Requester chest]] in the [[Logistic network]] with the correct researches, allowing them to 'request' various items be kept at a set limit within their personal inventory. After [[Research|researching]] [[Character logistic slots]], they can configure an amount of Items; and [[Logistic robot]]s will start to move the specified [[Items]] from the network to the character's inventory.

Do not mix up LogNet and [[Circuit network]]. They share common components, but are otherwise disconnected and do not exchange any information. Also, do not mix up logistic network with construction network or combinations of the two called [[Robotic network]].

== Achievements ==
{{Main|Achievements}}
The logistic network is directly connected to the following achievements:
; Logistic network embargo
: Win the game without building [[active provider chest]] and [[requester chest]].
; You've got a package
: Supply the player by [[logistic robot]].
; Delivery service
: Supply the player with 10k items delivered by logistic robots.

== Items ==
{| class="wikitable"
| {{imagelink|roboport|Roboport}} || Centre of the [[Robotic network]] in which the [[Robots]] can move and with its coverage forming the logistic network.
|-
| {{imagelink|Logistic-robot|Logistic robot}} || Moves items between Logistic Chests. (*)
|-
| {{imagelink|Provider-chest|Active Provider chest}} || Logistic Chest: Supplies the contained items to the logistic network. (**)
|-
| {{imagelink|Logistic-chest-passive-provider|Passive Provider chest}} || Logistic Chest: Supplies the contained items to the logistic network passively. (**)
|-
| {{imagelink|storage-chest|Storage chest}} || Logistic Chest: Stores [[Items]] currently not requested. Supplies the contained items to the Logistic network. (**)
|-
| {{imagelink|Requester-chest|Requester chest}} || Logistic Chest: Will be filled by [[Logistic robot]]s until the configured amount is reached, or the chest becomes full. Can request multiple different types of items. (**)
|}

(*) At the beginning each robot can carry only 1 [[Items|item]]. This amount can be increased by researching [[Logistic robot cargo]].

(**) Logistic chests are also usable for a [[Circuit network]] by using wires, like [[red wire]] or [[green wire]].

== Use ==

To start with, just use passive provider- and requester chests. Place the passive provider chests at the output [[inserters]] of [[assembling machine]]s and requester chests at the input (let them request the needed items). Place a [[Roboport]], which covers these chests with the inner orange area. Place some logistic bots. The robots will fly out of the top hatch and will begin to work. You can now limit the number of produced item either with the [[Storage/Stack#Stack limitation|stack limitation]]-feature.

Logistic network is very capable for creating more and more complex items in a relatively small factory-area. Low complexity and high volume activities over longer distances (like smelting) can (and should) be left using belts or railway network.

The basic thing needed are [[Roboport]]s. When placing the port and hover over it, notice an orange and a larger green area.

* The orange zone is the Logistic Network area. This is also the maximum distance for connecting two roboports.
* The green zone is the Construction area.

''For more info on the specifics of how [[roboport]]s work, check the page dedicated to them.''

=== Expand the logistic zone ===

There can be many separate logistic networks. Two roboports are in the same network only if they are connected, as described above. To prevent roboports from linking, the Player needs to build them far enough away from each other so that the orange zones don't touch.

Bots do not fly from one network into another, unless requiring a recharge. Robots will never "nest" in a different network.

=== Losing bots ===

Logistics robots are a priority target of biters, and will prioritize attacking them over many objects in the vicinity of the robots. Destroyed robots will not be replaced, unless automatic control of the robot creation system is used.

Bots are not destroyed when running out of energy, but will be reduced to 20% of their speed, which gives them the chance to recharge eventually and a chance for the player to notice the problem.

Pay attention to robotic networks which form some kind of U-shape (where the shortest way between two chests goes over an uncovered area): if a bot runs out of charge in this area, and cannot return fast enough to a roboport, the bot will be significantly slowed and as a result the logistics network will frequently slow down, with large groups of bots slowly flying over the uncovered area.

Robots may run out of charge on longer journeys. When the charging-queue for the bots gets too long, the bots (and their loads) will slow down. Generally, a roboport can charge between 50 and 70 bots per min, 4 at a time, but are not very efficient at charging large queues of bots and can quickly become overworked. Place more roboports near the first one to share the load.

=== Negative numbers ===
It is possible to notice negative numbers on the right info panel when looking at network storage. Contrary to common belief, this is intended.

The logistic network numbers report items in provider and storage chests, ''minus the amount of items scheduled to be picked up by robots.'' When negative numbers are shown, it means that more items are being requested than are available in the network. There is a deficit. This can be a problem, or intended, depending on the player's choice. The negative value is just to explain why items aren't being delivered. For example, a deficit of 20 iron plates would look like this:

{{icon|iron plate|-20}}

=== Receiving more items than requested ===

The delivered number of items in the requester chest can be higher than requested. This depends from the [[Logistic robot cargo]]-bonus you have researched, since bots will always take as much as they can carry if an unlimited amount is available.

== Priorities of robots ==

This overview reflects the priorities in which order the chests are filled/emptied.

The logistic network looks for orders by the chests in this order:

* A ''requested'' item is first looked up in the active provider chests, then in the storage chests, then the passive provider chests. So, the active provider chests are emptied first, then the storage chests, then the passive provider chests.
* If robots are free and there is space left in storage chests, and there are unrequested items in an active provider chests, the items are moved from active provider to a storage chest.
* For the storage chests, the bots search for one storage which has the same item already. If that can't be found, they choose the first storage chest with a free slot from the list, which is sorted by the order they were built in. [https://www.reddit.com/r/factorio/comments/5udwkd/hey_devs_this_is_the_one_thing_that_really_bugs/ddwbr94/] This is to avoid having storage chests with different items inside, allowing greater organisation.

Storage chests will be filled with items from active provider chests, and from construction robots that have had their orders cancelled while they were carrying items.

=== Order of movement ===
The bots fulfill '''all requests with the same priority'''. The algorithm looks for the next free robot, then the next request in the queue and after giving orders to the robot, this request is put at the end of the queue, so that first all other requests are done.

=== Distance ===
When choosing between chests of equal priority, bots will always choose the closest one. [https://forums.factorio.com/viewtopic.php?f=6&t=40329&p=238918#p238901] This is however only true when an item is being requested, not when an item is sent away. [https://gfycat.com/HatefulUnlawfulErmine] In the case of items being sent into the logistics network distance does not matter, and the rules laid out above matter instead.

Rail planner

2017-03-30T11:26:10Z

LowBattery: /* See Also */

{{Languages}}

The rail planner is a new feature introduced with Version 0.13 that allows tracks to be built in a more intuitive way that they had previously been built.

== Instructions ==

=== Starting the planner ===

To use the rail planner, craft and place a single rail, then mouseover the rail that was placed while still holding rails in hand. A green arrow/triangle should appear, like the example on the right.

[[File:rail_planner_starter.jpg|thumb|300x300px|The small green arrow used to start the planner.]]

Then, choose the type of planner by either left clicking or shift-left clicking the triangle.

=== Manual Planner ===

[[File:Manual_rail_planner.jpg|thumb|300x300px|The rail planner operating in manual mode.]]

The manual planning mode can be selected by left clicking on the triangle that appears. This will allow the player to place rails close range, about 10 rails at a time at max. The rails will be placed towards the cursor, simply aim with the cursor and left click again to place. This will be repeated. To escape the planner, press <code>Esc</code> to release the planner.

=== Ghost Planner ===

[[File:Ghost_rail_planner.jpg|thumb|300x300px|The rail planner operating in ghost mode.]]

The Ghost planning mode can be used to place longer stretches of rail at once, by creating ghosts of rails that can be filled in by [[construction robot]]s, either from [[roboport]]s or a [[personal roboport]]. To use ghost planning mode, shift-left click the green starter triangle. Then, move the cursor to where you want the rail to terminate, press R to rotate the last rail to the desired rotation, and left-click to place the ghost rails.

The AI will find a path from the starter location that does not go through obstacles, instead weaving and winding between them. If you'd rather the rail planner choose the shortest route, shift-left click to place. Trees and stone rocks in the way will be marked for deconstruction. To escape the planner, press <code>Esc</code> or <code>Q</code>.
