Redundant master station
For the redundant master station, the master station (1) and the submaster station (2) are connected with a tracking cable.
When an error occurs in the control system master station, the control is switched to the standby system submaster station to
control the slave stations and continue data link.

■Setting method
When using the module in a redundant master station configuration, select "RJ71GF11-T2 (MR)" for the module model name
in the "Add New Module" window.
Set the station number of the standby system submaster station in "Network Configuration Settings" under "Basic settings."
Station numbers of both systems do not need to be set consecutively.
In a redundant system, since send data in the send range are transferred to the standby system (submaster
station) via tracking, the same send data as those for the control system (master station) do not need to be set
to the standby system (submaster station).
Redundant slave station
For the redundant slave station, the slave station is made redundant and connected to one network line. When an error
occurs in the control system slave station (1), the control is switched to the standby system slave station (2) to control the
slave station side and continue data link.
Remote head modules can be also used as slave stations. For the remote head module redundant slave
station, refer to the following.

The system A and system B station numbers of the slave station to be made redundant are set as consecutive station
numbers.
