Fault inputs

12.7.1 Universal fault inputs

The RMK770 provides 4 universal fault inputs. These can be activated in the extra
configuration.
Analog or digital inputs can be defined as fault inputs. Inputs D1 and D2 at the RMK770
can only be used as digital fault inputs.
If the input is not assigned to an input that has already been configured, the input identifier
and thus the type of input or the unit can be freely selected.
