Function of switch S3
Table 42: Switch S3: SGND - GND
Switch setting Function
ON GND of the trigger sensor connected with GND of CDB620-001 and
CMC600
OFF Trigger sensor connected potential-free at CDB620-001 and CMC600.
Common, isolated reference potential of all digital switching inputs is
SGND.
Functional principle of the external switching inputs
As a software-controlled operation, the CMC600 automatically transmits the output
states of its physical digital switching inputs “In 1” and “In 2” in the connection module
via the connecting cable to the serial Aux interface of the device. The device internally
implements the states for its logical inputs “External input 1” and “External input 2”.
NOTE
The external digital switching inputs are software-defined. This results in a delay of max‐
imum 15 ms when transmitting the signal input at the CMC600 to the device.
