Comm Function is connected via communication and therefore does not
occupy a hardware input. Some signals can also be connected via
communication (see lists in the documentation on the basics for
LON, ModBus, BacNet).
Signals may generally be enabled in parallel as well (via hardware
and communication).
The value selector must be set accordingly when enabling via com-
munication (for details page on Digital Inputs, Sec.
6.6.2.).
NUsd No used: The hardware position is not yet selected. The plant is
locked against switching on if an enabled sensor is set to NUsd and
the following fault issued: NotConfigured (Function enabled, but
hardware not assigned).
15.3.6 Digital alarms
The listed hard assignments are possible for all digital alarms.
