Potential group
You can use the "Potential group" parameter to specify whether the module is inserted in a
light-colored or dark-colored BaseUnit.
A potential group always starts with an I/O module that is inserted on a light-colored
BaseUnit. All modules inserted to the right of this on dark-colored BaseUnits belong to the
same potential group, because the dark-colored BaseUnits are supplied via the light-colored
BaseUnits.
The potential group ends with a new light-colored BaseUnit or the end of the station.

control.
See section Normal operation/Valve control (Page 18).
