Function of switch S3

Switch setting Function
ON GND of the trigger sensor connected with GND of CDB650-204 and
CMC600.
OFF Trigger sensor connected potential-free at CDB650-204 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 “EXT. IN 1” and “EXT. IN 2” in the connec‐
tion 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.
