ATTENTION

ATTENTION

Follow these guidelines for environment and enclosure information for this equipment.

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:

Follow these guidelines when you handle this equipment.

• Industrial Automation Wiring and Grounding Guidelines, Rockwell
Automation publication 1770-4.1

• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the
degrees of protection provided by different types of enclosure.

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.

compliant with the following:
Class 2 or Limited Voltage/Current.

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

The 1747-SDN Series D module includes all features provided in the Series C module. The
module has the following software and hardware features.

, for additional information on these new enhancements.

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.

1747-SDN DeviceNet Scanner Module 5

This feature has the following variations.

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

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.

Pass-through

The SLC 500 pass-through feature allows communication with the DeviceNet network from
another network. This feature can be used to adjust and fine tune the nodes on your network.

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.

Pass-through Requirements
