Example of function blocks
Pulse width modulation (PWM) functions
The following PWM functions can be configured using a programmable logic controller (PLC) and arithmetic blocks:
| Function | Arithmetic block | Configuration |
|---|---|---|
| Outside temperature | Outside temperature, arithmetic block | For a configuration example, see "PSM arithmetic, example for PSM function" |
| Display dimming | Display dimming, filter block | For a configuration example, see "PSM arithmetic, example for PSM function" |
| Vehicle speed signal | Vehicle speed signal, differentiator/integrator | For a configuration example, see "PSM arithmetic, example for PSM function" |
| Interior temperature | Interior temperature, constants | For a configuration example, see "PSM arithmetic, example for PSM function" |
| Terminal 58D | Circuit 58D, comparator block | For a configuration example, see "PSM arithmetic, example for PSM function" |
| Engine speed | Engine speed, characteristic block | For a configuration example, see "PSM arithmetic, example for PSM function" |
The travel distance is not configurable and is always issued at "MFA 15".
Freely configurable PWM
Comparable configurations can be used to generate signals with freely configurable pulse width modulation.
Freely configurable PWM can be output at multifunction outputs MFA 13 and 14; MFA 9-12 and MFA 25; MFA 15-18. For the conditioning of signals, the arithmetic unit and the PLC logic unit provide appropriate arithmetic blocks and constants for configuration.
