Process data
The measuring device has a current output.
• In the IO-Link communication mode, pin 4 of the M12 plug is reserved exclusively for
communication
• The current output at pin 2 of the M12 plug is always active and can be optionally deac-
tivated via IO-Link
• The measuring device's process data are transmitted cyclically as per SSP 4.3.3

Reading out and writing device data (ISDU – Indexed
Service Data Unit)
Device data are always exchanged acyclically and at the request of the IO-Link master.
Using the device data, the following parameter values or device statuses can be read out:
