Data sent from the standby master station to the remote input RX and
remote register RWr in the standby master station (shown by the shaded
areas in the figure above) is used as output data when the master
station becomes faulty; it should be saved in another device using the
sequence program.
When the standby master station becomes faulty, the saved data is
transferred to the remote output RY and remote register RWw in the
master station using the sequence program.

local stations are operating; thus, it does not need to be saved in another
device.
