■States of safety remote inputs (SA\X0, SA\X1) for X0 and X1 (double wiring)
Input terminal status: X0
Input terminal status: X1
SA\X0
(1)
SA\X1
(1) Even when the input terminal X0 turns on, SA\X0 does not turn on because X1 is off.
(2) When the double inputs are on (X0 and X1 are on), SA\X0 and SA\X1 turn on.
External input signal monitor function
The state of input terminals can be monitored. This function facilitates the investigation for the cause of a double input
discrepancy error. For details, refer to the following.
Page 174 External input monitor
External input monitors are the remote control/monitor signals to investigate the cause of a double input
discrepancy error. Do not use them in a safety program.
Setting method
Set the input wiring selection in "Wiring selection of input" 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.

Item
Wiring selection of input X
• When Wiring selection of input Xn is set to "0: Not used", input data is always off.
• When Xn (n: even number) is set to "1: Double wiring (NC/NC)", only the same setting value as Xn can be
set for Xn+1, the partner of Xn. If a different value is selected and the parameter is set, "Parameter data
error (wiring selection of input): 0511H" occurs.
• When Wiring selection of input Xn (n: even number) is set to "1: Double wiring (NC/NC)", set Xn+1, the
partner of Xn, to "1: Double wiring (NC/NC)".
• For unused input terminals, set "0: Not used" in "Wiring selection of input".
