Discrete inputs and outputs 

The parameterizable special module (PSM) control unit (N26/16) is connected to the interior CAN (CAN B). This connection makes it possible to access vehicle status information with the parameterizable special module (PSM) control unit (N26/16) and to control vehicle functions.

A list of the signals available for this purpose can be found in the chapter "Signal list and description" in the document "Signal lists, PSM, function".

A list of controllable vehicle functions can be found in the chapter "Vehicle functions" in the document "Functional scope, PSM, function".

The parameterizable special module (PSM) control unit (N26/16) has various discrete inputs and outputs. The inputs are debounced and stored as a signal in the signal pool.

The logical status "1" means that the respective switch at the input is active, irrespective of whether the input is positive-active or ground-active.

The individual outputs are assigned signals by means of coding. 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).

IMPORTANT Further information on the inputs, e.g. internal wiring, can be found in the "Technical data" documents.
