8 FUNCTIONS
8.5 Input Diagnostic
Double input discrepancy auto recovery function
When a double input discrepancy detection error has occurred, removing the error factor recovers the module into the normal
state automatically.
By enabling this function, the reset operation of the safety remote I/O module to reset errors is not required.
When this function is enabled and a double input discrepancy is detected, the minor error state is applied to the safety remote
I/O module. For details on the error state, refer to the following.

■
Auto recovery timing
To clear a double input discrepancy detection error, turning off both of the actual input signals is required. The following figure
shows the timing of when the module is automatically recovered from a double input discrepancy detection error.
■
Double input discrepancy detection state
The double input discrepancy detection state can be monitored with the safety remote inputs (SA\X8 to SA\XB).
Do not use the double input discrepancy detection state in a safety program.
■ Setting method
Set the double input discrepancy auto recovery function in "Double input discrepancy auto recovery setting" from the
"Parameter of Slave Station" window of the engineering tool.
The double input discrepancy auto recovery setting function is valid only for the input signals for which "0:
Detect" is set in "Double input discrepancy detection setting".
(1) Both SA\X0 and SA\X1 turn off when discrepancy is detected.
(2) A double input discrepancy detection error occurs.
(3) The auto recovery is not performed even though both X0 and X1 turn on.
(4) The auto recovery is performed when both X0 and X1 turn off.
