This word is used to determine the status of the digital I/O by reading one parameter.
Pr 15.20 contains a binary value 'xx'. This binary value is determined by the state of Pr 15.04 to Pr 15.07. So for example, if all terminals were active
the value displayed in Pr 15.20 would be the sum of the binary values shown in the table, i.e. 120.

Destination parameters define the parameter each of the programmable inputs is to control. Only parameters that are not protected can be controlled
by the programmable digital inputs. If a non-valid parameter is programmed, the digital input is not routed anywhere.

This parameter defines the parameter to be represented by the status relay. Only valid parameters can be selected as a source for the relay output. If
a non-valid parameter is programmed, then the relay will remain in the last known state.
