Output modules

The output modules monitor the function of the outputs.
The output module generates an error signal and reports it to the controller if
a diagnostic message from the driver of an output channel is present.

8.4 Pressure measurement module
Pressure measurement modules monitor the sensor voltage in the internal pressure sensors. The
pressure measurement module generates an error signal and reports it to the controller if
the sensor voltage of the internal pressure sensor is outside the error thresholds.
