ATTENTION!

Observe current consumption of the modules!

On project planning of an AirLINE station, observe the current consumption of the logic of
each participant! This is given in each module-specific data sheet. It may differ from
module to module. Hence the number of possible participants that can be connected
depends on the specific construction of the station.
