3 Input signal
4 Filtered input signal
5 Filter time
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
0
exceeds the
filter time, which means that the change in the input state is detected and the time tag
attached to the input change is t
0
. The high state starting from t
1
is detected and the
time tag t
1
is attached.
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").

Parameter Values Default
Input # filter time 5...1000 ms 5 ms
3.10.2 Binary input inversion
The parameter Input # invert is used to invert a binary input.
