6.12 Wiring the digital switching outputs
Physical switching outputs on the device
The two physical digital switching outputs “Result 1” and “Result 2” are used to signal
events in the read operation. Different functions can be assigned to them indepen‐
dently of each other for this purpose. If the assigned event occurs, then the correspond‐
ing switching output becomes live after the end of the read cycle for the selected pulse
duration, for example (default).
The full complement of digital switching outputs is available in each case:
•
at the male connector of the device (M12, 17-pin, A-coded)
•
at the adapter cable (female connector, M12, 17-pin, A-coded/male connector, D-
Sub-HD, 15-pin)
•
at the open end of the adapter cable (female connector, M12, 17-pin, A-coded /
open end)

Attach a freewheeling diode directly to the load for this purpose.
Extension: additional logical switching outputs in the device for physical “external” dig‐
ital switching outputs on the optional connection module
Thanks to the optional CMC600 parameter cloning module in combination with the CDB
or CDM connection module, the two digital switching outputs “External output 1” and
“External output 2” are additionally available at the relevant terminals of the connection
module.
