SIO mode

13.2 SIO mode (standard IO mode)

In this mode, the sensor operates in the same way as a nor-
mal pressure sensor with standard output signals. The digital
output is always at pin 4 (output 1) of the M12 plug. Pin 2
(output 2) can be an analogue or additional digital output, de-
pending on the version.

13.3 IO-Link mode (communication mode)

The pressure sensor switches to the IO-Link communication
mode when it is operating under an IO-Link master. IO-Link
communication is only possible via pin 4 of the M12 plug.

13.4 Process data

The process data length of the sensor is 16 bits. Both the
switching states (BCD1 and BCD2) and the current measured
values are transferred. The 14 bits of the measured value are
scaled according to the sensor's measuring range.
