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, calculation block | For a configuration example see "PSM arithmetic, example of PSM function" |
| Display dimming | Display dimming, filter block | For a configuration example see "PSM arithmetic, example of PSM function" |
| Speed signal | Speed signal, differentiator/integrator | For a configuration example see "PSM arithmetic, example of PSM function" |
| Vehicle interior temperature | Vehicle interior temperature, constants | For a configuration example see "PSM arithmetic, example of PSM function" |
| Terminal 58D | Terminal 58D, comparator block | For a configuration example see "PSM arithmetic, example of PSM function" |
| Engine speed | Engine speed, characteristic block | For a configuration example see "PSM arithmetic, example of PSM function" |
The distance is not configurable and it is always issued at "MFA 15".
Freely configurable PWM
Comparable configurations can be used to generate signals with freely configurable pulse width modulation.
The freely configurable PWM can be output at the multifunction outputs 03, ngen 0306 (MFA 6), 07 and 20. For the conditioning of signals, the arithmetic unit "AU" and the PLC logic unit provide appropriate arithmetic blocks and constants for configuration.
