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 figure above) is used as output data when the standby master
station becomes faulty; it should be saved in another device using the
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 program.
