A-B 1747-SDN DeviceNet Scanner Module

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.

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.

The 1747-SDN module communicates with DeviceNet devices over

the network to:

• read inputs from a device.

• write outputs to a device.

• download configuration data.

• monitor a device’s operational status.

The 1747-SDN module communicates with the processor in the form

of M1/M0 File Transfers and/or Discrete I/O. Information exchanged

includes the following:

• Device I/O data

• Status information

• Configuration data

A processor to I/O DeviceNet configuration is shown in the following

figure. See the referenced chapters for more information.
