Types/EffectTypeLimitation

A list of module effects or just one module effect as a string. Modules with other effects cannot be used on the machine. This means that both effects from modules and from surrounding beacons are restricted to the listed effects.

Value	Module type
speed	Modules that increase or decrease the machine's speed.
productivity	Modules that make the machine produce bonus items.
consumption	Modules that increase or decrease the machine's energy consumption.
pollution	Modules that make the machine produce more or less pollution.

Example: (allows all module types)

allowed_effects = {"speed", "productivity", "consumption", "pollution"}

Allows only speed affecting modules:

allowed_effects = "speed"

Note: If the time to complete a recipe is shorter than one tick, only one craft can be completed per tick, but productivity bonus is applied to the non-limited completable work. For a simple example, if a recipe were to take half a tick, only one recipe would be completed, but twice the productivity bonus would occur. The surplus production from productivity is not limited to one craft per tick.
