General 

The parameterizable special module (PSM) control unit also has a connection to the CAN network. This connection makes it possible to access the vehicle status with the PSM control unit and to control vehicle functions.

Function 

The PSM control unit has various inputs and outputs. The inputs are debounced and stored as a signal in the signal pool. The individual outputs are assigned signals by means of parameterization. In the case of outputs with special functions (asymmetrical half-bridge) and pulse width modulation (PWM), additional information regarding their use is required. If the respective signal is "1" (active), the output is activated. Activation is performed irrespective of the switched level (low-side or high-side).

The PSM interfaces comprise the following interfaces:

• PSM inputs interface
• PSM outputs interface
• CAN interface
