Double input discrepancy detection time
Even if double input discrepancy is detected, an error does not occur during the set detection time. The logic of input signals
is evaluated and is reflected to the safety remote inputs (SA\X).
The following tables list the relation of each double input evaluation result and the double input discrepancy detection time.
The relation varies depending on a combination of double inputs.

Setting procedure
Set the double input discrepancy detection time in "Double input discrepancy detection time" from the "Parameter Processing
of Slave Station" window of the engineering tool.
For the procedure to display the "Parameter Processing of Slave Station" window, refer to the following.
