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
time, which means that the change in the input state is detected and the time tag attached
to the input change is t . The high state starting from 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).
