Type Switching
Switching behavior Power to the input starts the assigned function, e.g. start of the
internal reading gate of the device. Default: active high, debounce
time: 10ms (standard)
Properties
•
Opto-decoupled, reverse polarity protected
•
Can be wired with PNP output of a trigger sensor

Optional: additional, external digital inputs in the connection module
The optional CMC600 parameter cloning module in combination with the Connection
Device Basic or Connection Device Modular connection module offers two additional
external digital inputs for the device.
In this case the physical digital inputs “External input 1” and “External input 2” are
available at the respective terminals of the connection module. The CMC600 transmits
the switching signals of the two external digital inputs to the device via its serial data
interface. The device converts the switching signals internally into states of its logical
inputs “External input 1” and “External input 2”.
For the signal designations of the terminals of the two external digital inputs, see the
connection diagrams for the connection modules in these operating instructions.
NOTE
The external digital inputs are not suitable for time-critical applications.
Function assignment
NOTE
Assign the functions for the external digital inputs in the device using a configuration
tool, e.g., the SOPAS ET configuration software.
