Configuration of the Digital Inputs
Based on the »assignment list«, the states of digital inputs are allocated to
the module inputs.
Set the following parameters for each of the digital inputs:
•
»Nominal voltage«;
•
»Debouncing time« : A state change will only be adopted by the digital input after the debouncing time
has expired; and
•
»Inverting« (where necessary).
The debouncing time will be started each time the state of the input signal
alternates.
In addition to the debouncing time that can be set via software, there is
always a hardware debouncing time (approx 12 ms) that cannot be turned
of.
