Data sent from the standby master station to the remote input RX and remote register RWr in the master station (shown by
the shaded areas in the above diagram) are used as the output data in case of the standby master station's failure.
In the event that the standby master station becomes inoperable, the saved data are then transferred to the master station's
remote output RY and remote register RWw using the sequence program.

Data sent to the master station's remote output RY and remote register RWw are used by the master station as input
information to operate the local stations. Thus, there is no need to save these data in another device.
