Publication 1747-IN058F-EN-P - December 2010
Follow these guidelines for environment and enclosure information for this equipment.
Follow these guidelines when you handle this equipment.
ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 m (6562 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment according
to IEC/CISPR Publication 11. Without appropriate precautions, there may be
potential difficulties ensuring electromagnetic compatibility in other
environments due to conducted as well as radiated disturbance.
This equipment is supplied as open type equipment. It must be mounted within
an enclosure that is suitably designed for those specific environmental
conditions that will be present and appropriately designed to prevent personal
injury resulting from accessibility to live parts. The enclosure must have
suitable flame-retardant properties to prevent or minimize the spread of flame,
complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if
non-metallic. The interior of the enclosure must be accessible only by the use
of a tool. Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, Rockwell
Automation publication 1770-4.1, for additional installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the
degrees of protection provided by different types of enclosure.
ATTENTION
This equipment is sensitive to electrostatic discharge that can cause internal
damage and affect normal operation. Follow these guidelines when you handle
this equipment.
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wrist strap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation if available.
• Store the equipment in appropriate static-safe packaging when not in use.

About the 1747-SDN, Series D DeviceNet Scanner Module
The 1747-SDN, Series D module includes these firmware enhancements.
• ADR user memory space increased from 64K to 256K
• Support added for Online Scanlist Changes in Run Mode. This feature allows scanlist
changes to be downloaded to the scanner when the both the SLC processor and the
scanner are in RUN mode.
• Scanner CCV attribute supported, provides optimization for RSNetWorx.
Refer to the SLC 500 DeviceNet Scanner Module User Manual, publication
1747-UM655, for additional information on these new enhancements.
The 1747-SDN Series D module includes all features provided in the Series C module. The
module has the following software and hardware features.
Software Features
The module has these software features.
Slave Mode
Slave mode allows processor-to-processor communication and enables the scanner to
perform as a slave device to another master on the network.
When the scanner module is in slave mode, it exchanges data with only one master. You
control what information is exchanged through scan list configuration and associated
mapping functions of RSNetWorx for DeviceNet software.
ATTENTION
To comply with UL restrictions, this equipment must be powered from a source
compliant with the following:
Class 2 or Limited Voltage/Current.

1747-SDN DeviceNet Scanner Module 5
Publication 1747-IN058F-EN-P - December 2010
This feature has the following variations.
Poll
A poll message is a point-to-point transfer of data (0…255 bytes) sent by the scanner module
that solicits a response from a single device. The device responds with its input data
(0…255 bytes).
Strobe
A strobe message is a multicast transfer of data (64 bits in length) sent by the scanner module
that solicits a response from each strobed slave device. There is one bit for each of the
possible 64 node addresses. The devices respond with their data, which can be as much as
8bytes.
Change of State
Change of state enables the scanner module to perform a scan:
• whenever a network data change occurs.
• at a user-configurable heartbeat rate.
Because data is only sent on an as-needed basis, this feature increases system performance by
reducing network traffic.
Cyclic I/O
Cyclic I/O allows you to instruct the scanner module to perform a scan at a specific send rate.
Because data is only sent at a periodic rate, this feature increases system performance by
reducing network traffic.
Module Mode Description
Null Contains an empty or disabled scan list (default)
Master Serves as a master to one or more slaves but is not simultaneously serving as a slave to
another master
Slave Serves as a slave to another master
Dual Serves as both a master to one or more slaves and as a slave to another master
simultaneously

The pass-through feature is not intended to replace a 1770-KFD, 1784-PCD, 1784-PCID, or
1784-PCIDS connection to the network.
To use the pass-through feature you must meet the following hardware, software and
firmware requirements.
U2DN module
The pass-through feature is not intended to replace a 1784-U2DN, 1770-KFD, 1784-PCD,
1784-PCID, or 1784-PCIDS connection to the network.
Pass-through Requirements

For network communication, you have three options.
• Use the pass-through feature to communicate with the DeviceNet network from
another network. This method is intended for fine tuning and adjustment of network
devices.
• Use a 1770-KFD RS-232 DeviceNet adapter or 1784-PCD, 1784-PCID, or
1784-PCIDS DeviceNet PC card. This method is necessary for a complete network
configuration and real time monitoring of your network devices.
• Use a 1784-U2DN USB adapter, a 1770-KFD RS-232 DeviceNet adapter or
1784-PCD, 1784-PCID, or 1784-PCIDS DeviceNet PC card. This method is
necessary for a complete network configuration and real time monitoring of your
network devices.
Before you install your module you must know how to:
• program and operate an Allen-Bradley SLC 500 programmable controller.
• install and configure the devices on your DeviceNet network.
Electronic Data Sheet Requirement
This release of the scanner module requires the latest EDS file for RSLinx Classic and
RSNetWorx for DeviceNet software. If the software displays the device as an
Unrecognized Device, the EDS file must be installed.
You can download the latest EDS file online at:
http://www.ab.com/networks/eds
For FRN 8.002 and later, you can upload the embedded EDS file from the scanner module
itself.
1. Open RSLinx Classic or RSNetWorx for DeviceNet software and right click on the
Unrecognized Device.
2. Select Upload EDS file from device for RSLinx Classic software or Register
Device for RSNetWorx for DeviceNet software.
3. Follow the instructions in the EDS wizard to complete the installation.
Perform a ControlFLASH Update
If you want to upgrade the scanner module to a newer firmware release, you must perform a
ControlFLASH update. To get the kit, contact Rockwell Automation Technical Support at

1747-SDN DeviceNet Scanner Module 9
Publication 1747-IN058F-EN-P - December 2010
440.646.5800. To install the kit, refer to the ControlFLASH Firmware Upgrade Kit User
Manual, publication 1756-QS105.
Confirm Processor and Adapter Compatibility
Make sure that your processor and adapter are compatible. You can use the 1747-SDN
scanner module in any slot in an I/O chassis except for the leftmost, which is reserved for the
SLC 500 processor.
Install DeviceNet Scanner Module
Follow these steps to install the module.
1. Turn off the chassis power supply.
2. Select a slot for the module in the chassis.
You may use any slot except the leftmost slot, which is reserved for the SLC 500
processor.
IMPORTANT
You can update Series A and B scanner modules up to FRN 7.006. Series C
scanner modules support only FRN 8.001 to 8.006. Series D scanner modules
support FRN 9.001 and later.
IMPORTANT
You cannot use the scanner module in a remote I/O chassis with a 1747-ASB
adapter module. The adapter module does not support M-file transfer.
WARNING
If you insert or remove the module while backplane power is on, an electrical
arc can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
