■States of safety remote inputs (SA\X0, SA\X1) for X0 and X1 (double wiring (NC/NO))
Input terminal status: X0
Input terminal status: X1
SA\X0
SA\X1
(1) The same value as the input terminal is reflected.
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.
Setting procedure
Set the input wiring selection in "Wiring selection of input" from the "Parameter Processing of Slave Station" window of the
engineering tool.
For the procedure to display the "Parameter Processing of Slave Station" window, refer to the following.
Page 67 Module parameter setting procedure
Item
Wiring selection of input X0/X1 to XA/XB
When "Wiring selection of input" is set to "3: Single wiring", both Xn and Xn+1 are single wiring.
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 111 External input monitor (RX30 to RX3F)
External input monitors (RX30 to RX3F) are the remote control/monitor signals to investigate the cause of a
double input discrepancy error. Do not use them in a safety program.
