(1) Overview of link data transmission when the standby master
function is used
The following shows an overview of link data transmission when the standby
master function is used.
(a) When the master station controls the data link

Data sent from the 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; and therefore it should be saved in another device using
the program.
When the master station becomes faulty, the saved data is transferred to
the remote output RY and remote register RWw in the standby master
station using the program.

Data sent to the remote output RY and remote register RWw in the
standby master station is used as input data by the standby master
station when local stations are operating; thus, it does not need to be
saved in another device.
