Function of switch S6
Table 68: Switch S6: SGND - GND
Switch setting Function
ON GND of the trigger sensor connected with GND of CDM420-0001 and
CMC600
OFF Trigger sensor connected potential-free at CDM420-0001 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 “Aux In 1” and “Aux 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.
