Filters, Low Pass, Timers and Counters
The filter is configured using the table with the configuration values (see
Chapter 3.5, „Configuration Variables“).
Eight (8) special bits are defined that can implement the following functions:
1. Inverting,
2. Starting edge filter,
3. Low pass,
4. Pulse extension,
5. Monoflop, not retriggerable,
6. Pulse delay,
7. Math,
8. Counter, up,
9. Counter, up, stop at overrun,
10. Counter, down,
11. Counter, down, stop at overrun.
The functions Inverting and Starting edge filter react to the linkable input bit
and trigger the output immediately.
The functions Low pass, Pulse extension, Monoflop and Pulse delay react to
the linkable input bit and trigger the output in accordance with the selected
function at a time constant for which parameters can be assigned. This time
can be set between 0 … 16777215 ms.
