Inversion
You can invert the 24 V signal to adjust it to your process. By default, the signal is not
inverted.
Input delay
To suppress faults, you can set an input delay of 1 µs or 125 µs for the input filter of the
digital inputs. Changes to the signal are only detected if they are constantly pending for
longer than the set input delay time.
Hardware interrupts
In the Hardware interrupts section, you can assign a hardware interrupt to a rising and/or
falling edge.
