■ Redundant line
A redundant configuration of network lines is available.
Mount a CC-Link IE Field Network master/local module on each of the base units of the control system and standby system in
the master station where a redundant configuration has been configured. By mounting two remote head modules on the base
unit of a slave station, make a redundant configuration of the remote head modules. Connect between the master station and
the remote head module in the control system, and between the master station and the remote head module in the standby
system. With a redundant configuration of network lines, control is performed on a network of the standby system if an error
occurs on the network of the control system.
