Extension: additional logical switching inputs in the device in the case of physical
“external” switching inputs on the optional connection module
Thanks to the optional CMC600 parameter memory module, the two external switching
inputs “External input 1” and “External input 2” on the relevant terminals in the connec‐
tion module are additionally available.
NOTE
These two external switching inputs are not suitable for time-critical applications.
If the wiring of the inputs is carried out via a connection module, then the relevant oper‐
ating instructions for the module must be followed.
