Debounce times for standard and safety functions
The debounce time p0724 for "standard" digital inputs has no influence on the fail-safe input
signals. Conversely, the same applies: The F-DI debounce time does not affect the signals
of the "standard" inputs.
If you use an input as a standard input, set the debounce time using parameter p0724 .
If you use an input as a fail-safe input, set the debounce time as described above.
