III-4.4 BOUNCE (debouncer (No. 63))
This function is used for de-bouncing a logic signal. The change of input signal d1 is transferred to output z1 only,
when it remained constant for the time adjusted in parameter Delay. The time-out accuracy is dependent of the sam
-
pling interval assigned to the function.
Example:
–
Delay = 0,5s for assignment to
- sampling interval 100ms means that the signal is transferred only after ? 0,5s.
- Sampling interval 200ms means that the signal is transferred only after ? 0,6s.
- Sampling interval 400ms means that the signal is transferred only after ? 0,8s.
- Sampling interval 800ms means that the signal is transferred only after ? 0,8s.
