Preface

Introduction

This user manual is designed to provide you enough information to

get a small example application up and running. Use this manual if

you are knowledgeable about DeviceNet and SLC 500 products, but

may not have used the products in conjunction. The information

provided is a base; modify or expand the examples to suit your

particular needs.

The manual contains instructions on configuring a DeviceNet network

by using RSLinx and RSNetWorx for DeviceNet software. It also

describes how to use the SLC 500 pass-through feature to

communicate with the DeviceNet network for adjustment and tuning

of network devices via an Ethernet and Data Highway Plus (DH+)

network.

The example application demonstrates how to perform control on a

DeviceNet network by using an SLC 500 processor and the 1747-SDN

module. You use RSLogix 500 programming software to create a

ladder logic program to control a photoeye and a RediSTATION

operator interface.

Audience

This manual is intended for control engineers and technicians who are

installing, programming, and maintaining a control system that

includes an SLC 500 processor communicating on a DeviceNet

network through a 1747-SDN module.

We assume that you:

•are developing a DeviceNet network by using a SLC 500

processor in conjunction with a 1747–SDN module.

•know each of your device’s I/O parameters and requirements.

•understand SLC processor programming and operation.

•are experienced with the Microsoft Windows environment.

•are familiar with RSNetWorx for DeviceNet software.

IMPORTANT This user manual should be used in conjunction with the

1747-SDN DeviceNet Scanner Module Installation Instructions,

publication 1747-IN058. The installation instructions contain

important information on configuring your scanner.

The Example Application

This manual describes how to set up an example application. The

manual provides examples of each step of the setup, with references

to other manuals for more details.

System Components

We used the following devices and software for the example

application. For your own application, substitute your own devices to

fit your needs. The recommended configurations in this user manual

will help you set up the test system and get it working. Your eventual

configuration will depend on your application.

TIP If you use different software or fimware versions of these

products, some of your dialogs may appear slightly different

from those shown in the example.
