Description of Safety Functions
Section 1-4
If an error is detected, safety input data and individual safety input status will
turn OFF.
Setting Dual Channel Mode and Discrepancy Time
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.
IMPORTANT
The dual channel function is used with 2 consecutive inputs that start from
even input numbers: inputs 0 and 1, inputs 2 and 3, inputs 4 and 5, etc.
