Switching behavior
Power to the input starts the assigned function, e.g. start of the
internal reading interval of the device.
Default: active high
Debouncing: 10 ms (standard)
Features
•
Opto-decoupled, reverse polarity protected

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 inputs. They may therefore not be suitable for time-critical
applications.
