Preface

Purpose of This Manual

This manual describes how to understand, configure and troubleshoot

your ControlLogix Data Highway Plus/Remote I/O communication

interface module (1756-DHRIO module).

This manual also provides step-by-step procedures on how to:

·use the 1756-DHRIO module to send DH+ messages between

ControlLogix controllers, PLCs and SLCs in DH+ applications.

and

·connect ControlLogix controllers to remote I/O and send block

transfers via the 1756-DHRIO module.

Throughout this manual, we describe ControlLogix systems that use

the 1756-DHRIO module and ControlLogix controllers. Multiple

ControlLogix controllers are available. The examples contained in this

manual do not call out specific catalog numbers for ControlLogix

controllers. Whenever a controller is shown, any of the

controllers apply.

For a complete list of ControlLogix controllers, and a description of

each, see the ControlLogix Selection Guide, publication 1756-SG001.

Who Should Use This

Manual

This manual is intended for those individuals who program

applications that use 1756-DHRIO modules, such as:

·software engineers

·control engineers

·application engineers

·instrumentation technicians

We assume you have a good understanding of the Data Highway Plus

protocol and Remote I/O. This user manual contains a brief

description of Data Highway Plus in Chapter 2 and a brief description

of Remote I/O in Chapters 10 & 11.
