Preface

Using This Manual

What the Preface Contains This manual describes how to use the 1756-CNB or 1756-CNBR

ControlNet interface modules(1) to communicate over a ControlNet

network. This preface explains how to use this manual most effectively.

Who Should Use This Manual Use this manual if you are knowledgeable about ControlLogix products, but

need information about integrating them into a ControlNet network. You

should:

•be familiarwith Microsoft® Windows® NT and with terms that describe

what you should be doing when working in Windows NT, e.g., double

click, dialog box, radio button.

•understand basic networking concepts.

•be familiar with Logix5550 and PLC-5C controllers and ladder logic

programming using RSLogix5 and RSLogix5000 software.

If you are not familiar with these products and concepts or would like

additional information, refer to the documentation listed on page P-5 or

contact your Rockwell Automation representative for information about

available training.

How To Use This Manual Chapter 1 of this manual provides an overview of ControlNet

communications. Chapter 2 describes how to install the ControlLogix and

PLC-5C modules and connect them to the network. Chapter 12 provides

information on troubleshooting the 1756-CNB module. The remainder of

this manual (chapters 3 through 11) presents example applications of

scheduled and unscheduled communications among Logix5550 controllers

and PLC-5C controllers, and between a local Logix5550 controller and

remote I/O.

(1) Unless noted otherwise, for the rest of this manual 1756-CNB refers to both of these modules.

The example applications are intended to provide you with enough

information to get your own network up and running. We recommend that

you set up and run the example applications and use them as a guide for

setting up your own system.

About the Example

Applications

The example applications presented in this manual are as follows:

•Logix5550 controller to Logix5550 controller:

–unscheduled messaging (chapter 3)

–scheduled communications (chapter 4)
