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.
