ATTENTION
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 meters 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.
Throughout this publication, notes may be used to make you
aware of safety considerations. The following annotations and
their accompanying statements help you to i dentif y a potential
hazard, avoid a potential hazard, and recognize the
consequences of a potential hazard:

in a hazardous environment, which may
lead to personal injury or death, property
damage, or economic loss.
!
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 par ts. The inter ior 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.
See NEMA Standards publication 250 and
IEC publication 60529, as applicable, for
explanations of the degrees of protection
provided by different types of enclosure.
Also, see the appropriate sections in this
publication, as well as the Allen-Bradley
publication 1770-4.1 ("Industr ial Automation
Wiring and Grounding Guidelines"), for
additional installation requirements
pertaining to this equipment.

NOTE: Default scanner setting is Series C operation.
When replacing an older scanner , se t
configuration Switch 5 to the OFF position.
See Installation Instructions for details.
The 1771-SDN/C DeviceNet Scanner Module is fully compatible with
the Series A and Series B vers ions . You can use the Ser ies C vers ion as
a spare or replacement module with one requirement: you must
change the postion of Switch 5 to the off or “0” position in the
Configuration switchbank as show n bel ow :
Configuration
Chassis Address
The scanner revision is identified by RSNetWorx. In Series B mode,
the scanner is identified as Series B with major number as 4 and minor
number as 50. In Series C mode, the scanner is identified as Series C
with major number as 6 and minor number as 2 or higher.
To use the Series C module enhancements listed below, the scanner
module Configuration Switch 5 must be set in the on or “1” position.
Module Enhancements
Updated DeviceNet Master Library
Electronic Keying - added to include Major and Minor revision
checking.
Shared Inputs - multiple scanner modules can acquire the inputs
from a specific input device without using separate connections.
Auto Device Replacement (ADR) - consists of No de Recovery and
Configuration Recovery:
• Node Recovery - this feature causes the node number of the
replacement device to be automatically changed to the node
number of the original device. The replacement device’s node
number must be writable over the DeviceNet network and must
initially be set to 63.
• Configuration Recovery - this feature causes the replacement
device’s configuration to be made identical to the original device.
The replacement device’s configuration must be writable over the
DeviceNet network. Configuration Recovery files are stored in the
master scanner that is communicating with the original device
through RSNetWorx for DeviceNet.

Other Features
Change of State
Change of state enables 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, 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 spe c ific se nd rate.
Because data is only sent at a periodic rate, this feature increases
system performance by reducing network traffic.
Pass-Through
The 1771-SDN “pass-through” feature allows communication with the
DeviceNet network from another network. This feature can be used to
adjus t an d f i ne t une the nodes on your network.
For more information on how to use the pas s-throu gh feature, refer to
Chapter 5 of the PLC-5 DeviceNet Scanner Module User Manual,
publication 1771-6.5.132.

Hardware Requirements
The 1771-SDN Scanner Module is compatible only with the 1771-A1B
through 1771-A4B or later I/O chassis in any configuration supported
by the 1771 family.
Y ou can use the following chassis with the 17 71-SDN Scanner Module:
• Local I/O Chassis with only the PLC processor running in the
leftmost slo t
• Extended Local I/O Chassis with any 1771-ALX Adapter Module
running in the leftmost slot
• Remote I/O Chassi s with a 1 771-ASB Adapter Module ru nning i n
the leftmost slot or a PLC processor running in the leftmost slot
Publication 1771-IN014B-E N-P - September 2001
DeviceNet Scanner Module Catalog Num ber 1771-SDN/C 9
• Remote I/O Chassis linked to ControlNet with a 1771-ACN(R)
running in the leftmost slot
Do not use the 1771-SDN Scanner Module with the following:
• Chassis configured for complementary I/O
• Remote I/O chassis connected to a preceding chassis using a
1771-SN Sub I/O Scanner Module
IMPORTANT
The 1771-SDN Scanner Module fits in any slot of the
chassis except for the leftmost slo t, which is reserv ed
for the PLC processor. The scanner module will not
conflict with other 1771 I/O devices in the chassis.
You can install multiple scanners in the same chassis.
The 1771-SDN Scanner Module is compatible wit h any PLC-2
or PLC-5
processor that supports block transfer read and write
, PLC-3
instructions. The example configurations in these installation
instructions use a PLC-5 processor.
Perform the ControlFLASH Update
If you have the previous releas e of fi rmware and you want to up grade
it to this release, you must perform the ControlFLASH update. To get
the kit, contact Rockwell Automation Technical Support at
440.646.5800. To install the kit, refer to the ControlFLASH Firmware
Upgrade Kit User Manual, publication 1756-6.5.6.
Before you install your module you must set the following switches:
• data rate for each DeviceNet channel
• I/O cha ssi s a d dressing mode (1 /2, 1 or 2-sl o t ad dressing )
• scanner node address for each channel
