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.

What Your 1747-SDN
Module Does
In a typical configuration, the 1747-SDN module acts as an interface
between DeviceNet devices and the SLC 500 processor.
Typical DeviceNet Network
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

16 Before You Begin
Communicating with Your
Devices
The 1747-SDN module communicates with a device via strobe, poll,
change of state, and/or cyclic messages. It uses these messages to
solicit data from or deliver data to each device. Data received from the
devices, or input data, is organized by the 1747-SDN module and
made available to the processor. Data received from your SLC 500
processor, or output data, is organized in the 1747-SDN module and
sent on to your devices.
IMPORTANT Throughout this document, input and output are defined from
the SLC 500 processor’s point of view. Output is data sent from
the SLC 500 processor to a device. Input is data collected by the
SLC 500 processor from a device.
All data sent and received on a DeviceNet network is in byte
lengths. A device may, for example, produce only two bits of
input information. Nevertheless, since the minimum data size
on a DeviceNet network is one byte, two bits of information are
included in the byte of data produced by the device. In this
example (only two bits of input information), the upper six bits
are insignificant.

Different portions of data from a single
device can be mapped to separate
1747-SDN memory locations. For example,
On/Off values can be mapped to one
location, diagnostic values to another. This
is known as map segmenting. This concept
is illustrated by byte A, stored separately
as segments A1 and A2.

Communicating with Your
SLC 500 Processor
The 1747-SDN module does not send data to your processor. Data
transferred between the module and the processor must be initiated
by the processor. Output data is sent, or written, to the scanner by
your processor by placing the data in the M0 file. This data is
organized in the scanner, which in turn passes the data on to the
scanned devices via strobe, poll, change of state, or cyclic messages.

1747-SDN Module Data
Tables
To manage the flow of data between your SLC 500 processor and the
network devices, the 1747-SDN module uses the following data tables:
•Scanner configuration table (SCT)
•Scanlist table (SLT)
•Device input data table
•Device output data table
•Device active table
•Device failure table
•Client/Server transaction tables
You can configure the first two of these data tables through
RSNetWorx for DeviceNet software.
•Scanner configuration table (SCT)
•Scanlist table (SLT)
These two tables are stored in the 1747-SDN module’s nonvolatile
memory and used to construct all other data tables.
Scanner Configuration Table (SCT)
The SCT controls basic information your 1747-SDN module needs to
function on your DeviceNet network. It tells your 1747-SDN module:
•if it can transmit and receive input and output data.
•how long it waits after each scan before it scans the devices
again.
•when to send out its poll messages.
Scanlist Table (SLT)
The SLT supports I/O updating for each of your devices on the
network. It also makes it possible for your 1747-SDN module to make
device data available to your SLC processor. The SLT tells your
1747-SDN module:
•which device node addresses to scan.
•how to scan each device (strobe, poll, change of state, cyclic, or
any valid combination).
•how often to scan your devices.
•exactly where in each device’s total data to find the desired data.

Publication 1747-UM655B-EN-P - June 2007
20 Before You Begin
•the size of the input data/output data.
•exactly where to map the input or output data for your
processor to read or write.
•how your processor reads each device’s input data (M1/M0 file
or discrete I/O).
RSNetWorx Software as a
Configuration Tool
RSNetWorx for DeviceNet software is used to configure the 1747-SDN
module’s data tables. This software tool connects to the 1747-SDN
module over the DeviceNet network via a computer RS-232 interface
(1770-KFD module) or PC Card (1784-PCD, 1784-PCID, or
1784-PCIDS).
The configuration dialog map below shows the RSNetWorx for
DeviceNet dialogs used to configure the 1747-SDN module and the
navigation paths between them.
The use of these dialogs is described in Chapter 4.
