Appendix 1 Safety Remote I/O Signals
Details of safety remote input signals
Safety input signals
■
Device number
■
Description
These signals indicate the ON/OFF state of safety remote input (SA\X
) due to the external input signals (X
) of the safety
remote I/O module.
However, depending on the settings of the safety double wiring function and input response time, the ON/OFF state of the
safety input signals X
(SA\X
) and that of the actual external input signals (X
) may differ. For details on the safety double
wiring function, refer to the following.
Page 70 Safety double wiring function
When "Wiring selection of input" is set to "0: Not used" or "3: General single", the corresponding safety input
signal X
(SA\X
) is fixed to OFF.
When the ON or OFF state of the safety input signal X
(SA\X
) cannot be read, refer to the following.

Description
This area stores the double input discrepancy detection state. This area turns on when a double input discrepancy detection
error has occurred in a pair of the corresponding input signals.
