Function assignment
NOTE
Assign the functions for the digital inputs in the device using a configuration tool, e.g.
the configuration software SOPAS ET.
Extension: additional logical digital inputs in the device for physical external digital
inputs on the optional connection module
Thanks to the optional CMC600 parameter cloning module in combination with the
CDB or CDM connection module, the two digital inputs “External input 1” and “External
input 2” are additionally available at the relevant terminals of the connection module.
NOTE
The external digital inputs are software-controlled and therefore do not offer the same
timing precision as physical digital inputs. The external digital inputs may not be suit‐
able for time-critical applications.
For the electrical characteristic data of the two external digital inputs, see the respec‐
tive connection diagrams for the connection modules in these operating instructions.
