8 Operation Modes

8.1 SIO mode

After start-up, the pressure switch is in SIO mode (standard I/O mode). In this mode, Pin 4
serves as a switch output.
The mode display (LED Com) is constantly lit green.

8.2 SDCI Mode

Via a connected IO-Link master the pressure switch can be switched to the SDCI mode
(Single-drop digital communication interface for small sensors and actuators) by means of
a wake-up signal. In this mode, Pin 4 serves as a communication pin. The master is able
to communicate with the pressure switch in order to change parameters or to read out
measured values.
The mode display (LED Com) is flashing green.
