Influence of the supply voltage and operating state on the modules
The IO values of analog modules are determined by the CPU operating state and the
module's supply voltage.

Reaction to power failure
Power failure at analog modules is always indicated by their relevant SF LED. This
information is also available on the module (in diagnostic buffer data.)
Diagnostics interrupt triggering is based on parameter settings.
