Details
The digital inputs are used for control tasks. For this purpose, the digital inputs are available as
selectable triggers for functions.
The following settings are possible for the digital inputs:

Debounce time
For minimising interference pulses, a debounce time of 1 ms is set for all digital inputs.
Via »EASY Starter« (or network), the debounce time for can be increased individually for each
digital input to maximally 50 ms.
Inversion
Each digital input can be configured in such a way that the status pending at the terminal is
internally inverted logically. This way, a closed contact, for instance, serves to deactivate an
assigned function instead of activating it. Thus, the control of the inverter can be flexibly
adapted to the requirements of the actual application.
Manual I/O control
Each digital input can be overridden manually. After the function is activated, the actual val-
ues are "frozen". Afterwards, each digital input can be overwritten manually.
