The consistency between signals on two channels can be evaluated. Either of
the following settings can be selected. This function monitors the time during
which there is a discrepancy in the logic between the two channels set as dual
channels. If the length of the discrepancy exceeds the set discrepancy time (0
to 65,530 ms, in increments of 10 ms), the safety input data and the individual
safety input status will turn OFF for both inputs.
even input numbers: inputs 0 and 1, inputs 2 and 3, inputs 4 and 5, etc.
