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.

Logic inputs

d1 and d2 are combined into z1 according to the truth table given below. Unused inputs are inter-

preted as logic 0.
