The 1747-SDN/B has the following features. You activate these
features using DeviceNet Manager Software. For more information,
refer to your DeviceNet Manager Software User Manual (publication
number 1787-6.5.3) and your 1747-SDN Scanner Configuration
Manual (publication number 1747-6.5.2).
Slave Mode
The slave mode feature allows processor-to-processor
communication. Slave mode also allows the scanner to perform as a
slave device to another master on the network.
Like any other slave, 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 DeviceNet Manager software.

The slave mode function has the following variations:
The scanner is in: When:
Null Mode it contains an empty or disabled scan list (out-of-
box default)
Master Mode it serves as a master to one or more slaves but is
not simultaneously serving as a slave to another
master
Slave Mode it serves as a slave to another master
Dual Mode it serves as both a master to one or more slaves
and as a slave to another master simultaneously
Change of State
The change of state function notifies the scanner module to perform
a scan:
•whenever a network data change occurs, or
•at a user-configurable heartbeat rate
Because data is only sent on an as-needed basis, change of state
increases system performance by reducing network traffic.
Cyclic I/O
The cyclic I/O feature allows you to set the scanner module to
perform a scan at a specific send rate.
Because data is only sent at a periodic rate, cyclic I/O increases
system performance by reducing network traffic.
Other New Information
Along with these new features are areas in this document that are
different from the previous edition. These areas are marked with
change bars (as shown to the right of this paragraph) to indicate the
addition of new or revised information.

•Do not touch the backplane connector or
connector pins
•Do not touch circuit components inside the module
•If available, use a static-safe work station
•When not in use, keep the module in its
static-shield bag

•program and operate an Allen-Bradley SLC 500TM programmable
controller
•install and configure the devices on your DeviceNetTM network
Make Sure That Your Processor and Adapters are Compatible
You can use the 1747-SDN Scanner Module in a local I/O chassis
with only the SLC 500 processor running in the leftmost slot.
Important: The 1747-SDN Scanner Module fits in any slot of the
chassis except for the leftmost slot, which is reserved for
the SLC 500 processor.

SLC Memory Configuration ID Code
The ID code for the 1747-SDN scanner module is 13606. Use this
code to configure the memory of your SLC 5/02, 5/03 or 5/04
processor. Refer to the documentation supplied with your Advanced
Programming Software User Manual for additional information on
module ID codes and their use.
