Function of switch S6
Table 36: Switch S6: SGND - GND
Switch setting Function
ON GND of the trigger sensor connected with GND of CDM420-0006 and
CMC600
OFF Trigger sensor connected potential-free at CDM420-0006 and
CMC600.
Common, isolated reference potential of all digital inputs is SGND.
Functional principle of the external digital inputs
The optional CMC600 parameter cloning module in combination with the CDB or CDM
connection module offers two additional physical digital inputs for the device. The
inputs are available at the respective terminals of the connection module. To distin‐
guish them from the physical digital inputs directly on the device, these addition inputs
via the CMC600 are designated as “external inputs”.
NOTE
The CMC600 transmits the switching signals of the external digital inputs as statuses to
the local inputs of the device via its serial data interface.
The digital inputs are not suitable for time-critical applications.
