At the beginning, the input signal is at the high state, the short low state is filtered and
no input state change is detected. The low state starting from the time t
filter time, which means that the change in the input state is detected and the time tag
attached to the input change is t

Each binary input has a filter time parameter "Input # filter", where # is the number of
the binary input of the module in question (for example "Input 1 filter").
