Combination of double inputs
The safety remote I/O module evaluates the logic of input signals and reflects the results to safety remote inputs (SA\X).
When the double input signals differ, the double input discrepancy detection state is applied. The following tables list the
correspondence between each double input signal state and safety remote input (SA\X).

■States of safety remote inputs (SA\X0, SA\X1) for X0 and X1 (double wiring (NC/NC))
Input terminal status: X0
Input terminal status: X1
SA\X0
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.
Even when SA\X0 and SA\X1 are off, the time when X0 and X1 are in double input discrepancy state is measured and if the measured time exceeds a set
detection time, a double input discrepancy detection error occurs.
