Details of safety remote I/O signals

Safety input signals
■Safety input signal X (SA\X0 to SA\XB)
These signals indicate the ON/OFF state of safety remote input (SA\X) due to the external input signals (X0 to XB) of the
safety remote I/O module.
However, when the double wiring function and the noise removal filter function are enabled, the ON/OFF state of the safety
input signals X (SA\X0 to SA\XB) and that of the actual external input signals (X0 to XB) may differ. For details on the safety
I/O function, refer to the following.

Safety input status
■Safety input status X (SA\XC to SA\X17)
These signals store the safety input status. The safety input status is ON when the corresponding input signal is operating
normally. The safety input status is OFF when an error was detected in the corresponding input signal. For details on the
safety input status, refer to the following.

Safety output status
■Safety output status Y (SA\X18 to SA\X1B)
These signals indicate the ON/OFF state of the external output terminals.
They can be used to monitor the actual signals of the external output. For details on the safety output status, refer to the
following.

Safety output signal
■Safety output signal Y (SA\Y0 to SA\Y3)
These signals turn on or off each of the external outputs (Y0 to Y3) of the safety remote I/O module.
When the double wiring function is enabled, the ON/OFF state of the safety output signals Y (SA\Y0 to SA\Y3) and that of
the actual external outputs (Y0 to Y3) may differ. For details on the safety I/O function, refer to the following.
