■Setting method
Configure the double input discrepancy detection setting in "Double input discrepancy detection setting" and "Double input
discrepancy detection type" from the "Parameter Processing of Device Station" window of the engineering tool.
For the procedure to display the "Parameter Processing of Device Station" window, refer to the following.
Page 72 Parameter Settings
Item
Double input discrepancy detection setting Xn, Xn+1
*1 n: Even number
• When an item other than "1: Double wiring (NC/NC)" is selected in "Wiring selection of input", only "1: Do
not detect" can be selected for "Double input discrepancy detection setting".
• When double input discrepancy errors do not need to be detected during equipment maintenance including
system start-up and inspection, select "1: Do not detect".
Item
Double input discrepancy detection type Xn, Xn+1
*2 n: Even number
When "1: Do not detect" is selected in "Double input discrepancy detection setting", the setting of "Double
input discrepancy detection type" is ignored.
Double input discrepancy detection time
When the double input discrepancy detection time is set, an error does not occur during the set detection time even if double
input discrepancy is detected. The following table lists the relation of each double input evaluation result and the double input
discrepancy detection time.
