Appendix 2
This appendix lists the remote I/O signals for a master/local module.
The following shows an assignment example of I/O signals with the remote I/O signals of the safety remote I/O module
assigned to the I/O numbers of RX0 to RX4F and RY0 to RY4F.
Remote input (RX) are input signals from the safety remote I/O module to the master/local module.
Remote output (RY) are output signals from the master/local module to the safety remote I/O module.
The remote I/O signals of the safety remote I/O module are assigned as shown below.
Module
Safety remote I/O module
• These signals (RX/RY) are used to control and monitor functions other than the safety functions of the
safety remote I/O module.
• The external I/O signals of the safety remote I/O module are communicated to the master/local module
using the "safety remote I/O signals (SA\X and SA\Y)".
• Do not use these signals in a program that operates the safety functions. If any of the signals is used, the
correct operation of the safety functions of the module cannot be guaranteed.
• When "Link Stop" is performed using the CC-Link IE Field diagnostics and the cyclic transmission is
stopped from the link special relay (SB) or link special register, the input status of RX is held, and thus the
status may differ from the actual status of the module.

List of remote I/O signals

The remote I/O signals of the safety remote I/O module are assigned as shown below.
