Redundant System - Mitsubishi Electric MELSEC iQ-R Series Configuration Manual

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)
