Redundant system
This system consists of two systems and each of them has a CPU module, a power supply module, and a network module or
other modules. Even if an error occurs in one system, the other system continues control.
I/O modules and intelligent function modules used in a redundant system are mounted to the intelligent device station (remote
head module) on CC-Link IE Field Network.
A redundant configuration of power supply modules is available with redundant power supply base units and redundant power
supply modules. (Redundant power supply system)
Ethernet
The redundant system is categorized into the following types.
