Extension: additional logical switching inputs in the device for physical “external” digi‐
tal switching 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 switching inputs “External input 1” and
“External input 2” are additionally available at the relevant terminals of the connection
module.
NOTE
The external digital switching inputs are software-defined. This results in a delay of max‐
imum 15 ms when transmitting the signal input at the CMC600 to the device.
Function assignment
NOTE
Assign the functions for the digital switching inputs in the device with a configuration
tool, e.g. the configuration software SOPAS ET.
For electrical characteristic data of the two external digital switching inputs, see con‐
nection diagrams for the respective connection modules in these operating instruc‐
tions.
