Redundant line
In redundant line configuration, two network lines are prepared and a slave station is connected to each network line. (The
RJ71GF11-T2 of both systems operate as a master station of each network.)
When an error occurs in the control system network (1), the control is switched to the standby system network (2) to control
the redundant system and continue data link.
Ensure that the configuration of the network of both systems is the same.
(1)
For slave stations, only remote head modules configured as a redundant system can be used.
It is recommended that the network topology and Ethernet port for connecting an Ethernet cable be made the
same. Also, visually check the actual network configuration for the network configuration of both systems. The
CC-Link IE Field Network diagnostics may display a configuration different from the actual system
configuration.
