Sensor Usage
Whether an actuated sensor or an actuated mechanical contact represents an open or closed
valve position, depends on the design of the position feedback.
Therefore, the Sensor Usage parameters offer the following modes for configuring the MIO
device according to the individual requirements:
The signals of the position feedback sensors are defined as follows:
■
Sensor current high -> logical 1
■
Sensor current low -> logical 0
