Process data
The device has two switch outputs. Both outputs are transmitted as process data via IO-
Link.
• In the SIO mode, switch output 1 is switched at pin 4 of the M12 plug. In the IO-Link
communication mode, this pin is reserved exclusively for communication.
• In addition, switch output 2 is always switched at pin 2 of the M12 plug.
• The process data of the point level switch are transmitted cyclically in 16-bit chunks.

Coverage [0 to 100 %], resolution approx. 0.1 %
Bit 14 reflects the status of switch output 1 and bit 15 the status of switch output 2. Here,
the logical state "1" at the specific switch output corresponds to "closed" or 24 V
The remaining 14 bits contain the value for the coverage [0 to 100 %] following
conversion using the factor 0.1.

In addition, the coverage value can be read via ISDU (hex) 0x0028 – acyclic service.

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:
