The relay supply voltage supervision, derived from the 24 V
distributed on the ModuleBus, gives a channel signal error and a
module warning signal if the voltage disappears. The error signal and
warning signal can be read through the ModuleBus. This supervision
can be enabled/disabled with a parameter.
