It is possible to configure the operation of the digital input, either on falling edge/low level, or
on rising edge/high level.
Falling edge or low level (idem for rising edge or high level) depends of the application of the
digital inputs.
Example : a digital input configured "blocking logic" will operate on level, on the other hand a
digital input configured "Cold load pick up" will operate on edge.
ONLY a digital input configured "change of setting group" can operate either on edge
or on level.
