SETTINGS AND PROCEDURES BEFORE
OPERATION
(8) Safety stop and function stop
When using safety relay module, ON/OFF operation is made with the function stop
according to control target. In this case, use it together with safety stop.
Since only function stop may not stop the system, not doing so may cause a
malfunction.
Connect safety devices to X0 and X1 sides and cut off the output on control target
side.
