Circuit network

Circuit networks (CCNet) enables the control of devices based on the amount of Items and Fluids stored in all Chests and Storage tanks connected to the same network via red or green wires.

A more technical explanation is, that the circuit network is a standardized bus-system. See this explanation.

Even if the circuit network looks quite different to the Logistic network, the bus is principally the same beccause the information is the same. The basic difference between them is that, in a logistic network, everything which is covered by a roboport pops up as content, but in the circuit network only the connected chests and storage tanks were considered.

Items/Devices

Smart chest	The most basic chest connectable to Circuit networks. Its content will be sent to the network.
File:Provider-chest.png Active Provider chest	A chest connectable to Circuit networks and participating in the Logistic network. Its content will be sent to the network.

Smart inserter	The only inserter connectable to Circuit networks and Logistic networks. The condition when the inserter is working is configurable in the menu.

File:Constant-combinator.png Constant Combinator	The constant combinator is connectable to Circuit networks. You can set up to 15 signals in its GUI which will be sent to the network (like a chest that contains pseudo items). It has several outputs for red and green wires.
File:Arithmetic-combinator.png Arithmetic Combinator	The arithmetic combinator is connectable to Circuit networks. It can perform mathematical operations (+, -, *, /) based on the amounts of the inputs signals (red and green wire signals are summed).
File:Decider-combinator.png Decider Combinator	The decider combinator is connectable to Circuit networks. It acts like any signal controlled device. You can compare the input signals (red and green wire signals are summed) by using "less than", "bigger than" or "equal to". If the condition is true, it will output a configurable signal.

Basic

A basic circuit network usable to fill a chest with a defined amount of items. Watch exactly, how the red wires are connected!

The circuit network is often use to control the amount of certain items or fluids in the factory. Before the storage tank, lamp, small and offshore pump were included to the circuit network, the basic usage was to connect a smart inserter with a chest next to it to control the amount of items in the chest.

• To connect wires over long distances, you can use power poles by dragging the wire from the base of a pole to the target entity.
• To erase any wire connection, drag the same color wire over top an existing connection.
• To remove all connections – including electrical – from power poles, shift-click on the pole.
• When connecting to Decider Combinator or Arithmetic Combinator, take care to drag the wire to the correct input or outside side of the target entity.

Advanced

The picture shows a circuit network that contains over 42,000 coal and 12,000 iron plates.

The smart bus page explains the function of the bus.

There are several links into the forum (outdated):

• Forum article about the basic usage
• About comparison of the circuit wires with examples from the real world

Receivers

Example condition: "Work only if the count of Iron plates is lower than the amount of Steel plates." Instead of the steel plate you can use a constant value.

Smart inserters, Lamps, Small pumps and Offshore pumps are currently the only devices connectable to the circuit network. If a circuit condition is set, they only work if this condition is true. When it is connected to the network, it is possible to set up the condition in three parts:

• Item or fluid. To check the condition, the amount of the given item or fluid in the connected circuit network is taken.
• Type of the condition: less than, bigger than, equal
• Item or fluid. To check the condition, the amount of the given item or fluid in the connected circuit network is taken.

Both values will be compared by using the given type of the condition.

Multiple networks

It is possible to establish multiple distinct networks of the same color. Just make sure that there is no wire connection between them and they will be treated as separate networks.
