4.7 Digital input filters
The input signals can be changed via different filters before they are passed on via IO-Link. The
following filters are available and are applied to the input signal in this order:
1. Debounce
2. Hold
3. Inverting

Each of these filters can be configured separately via IO-Link. More information is available in the
IODD at documentation.ifm.com.
The device detects signals of a length of min. 2 ms. Shorter signals are not detected.
Periodic signals are only detected reliably if the signal period is at least twice as long as the
cycle time.
The precision of the digital input filters is ± 1 ms.
4.7.1 Debouncing
The input debouncing filter suppresses noise signals caused by mechanical switches, contacts or
relays. The filter provides the input signals at the filter output with a delay (debounce time). All signals
shorter than the set debounce time are ignored by the filter.
