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
