(1) Overview of link data transmission when the standby master
function is used
The following provides an overview of link data transmission when the standby
master function is used.

input RX
The master station data sent to the remote input RX in the standby master
station (shown by the shaded areas in the figure above) is used as the
output information when the master station becomes faulty; thus, it should be
transferred to another device using a sequence program.
In addition, when the master station becomes faulty, the transferred data is
transferred to the remote output RY of the standby master station using a
sequence program.

The remote I/O station data sent to the remote output RY of the standby
master station is being used by the standby master station as the input
information when the standby station operates as a local station; thus, it
does not need to be transferred to another device.
