*) PM56x has 2 analog inputs which can be configured as digital inputs. If the analog inputs are
configured as digital inputs, 8 digital inputs are available overall.
All digital inputs (DI0...DI5) belong to 1 group. All digital outputs (DO0...DO5 / NO0...NO5)
belong to 1 group. These inputs and outputs are group-wise galvanically isolated.
The 2 analog inputs are not galvanically isolated from the 24 V power supply of
the processor module.
