Preface

Manual Objectives

This manual shows you how to set up and apply a ControlNet

PLC-5

Hot Backup system. A backup system requires a pair of

standard PLC-5/40

or PLC-5/80

ControlNet programmable

controllers (Series F, Revision A or higher), with I/O remotely

connected to both PLC-5s via ControlNet.

Using ControlNet, the PLC-5s communicate with each other and with

ControlNet remote I/O to create a PLC-5 backup system that provides

high availability of control applications, where it is essential for

process continuity.

In this manual, we describe the following details of the ControlNet

Hot Backup system:

• system concepts

• required hardware and software components

• installation and configuration procedures

• system operation

• troubleshooting and diagnostics procedures

• system design considerations

Who Should Use This

Manual

Before you read this manual or attempt to use the ControlNet PLC-5

backup system, you should be familiar with the use and operation of

the ControlNet PLC-5 programmable controller. You should also be

familiar with:

• Remote I/O

• the ControlNet network

• RSLogix 5

programming software

• RSNetWorx

for ControlNet software

• RSLinx

communications software

IMPORTANT

For the ControlNet PLC-5 programmable controllers

to operate in backup mode, each PLC-5 must have a

new ControlNet Backup Cartridge (Cat. No.

1785-CHBM) inserted into its EEPROM memory

module slot.
