Function of switch S3
Table 41: Switch S3: SGND - GND
Switch setting Function
ON GND of the trigger sensor connected with GND of CDB650-204 and
CMC600
OFF Trigger sensor connected volt-free at CDB650-204 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 transmission of the input signals on the CMC600 to the device may be delayed by
up to 15ms.
