Important User Information
Solid state equipment has operational characteristics differing from those of electromechanical
equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls
(publication SGI-1.1 available from your local Rockwell Automation sales office or online at
http://literature.rockwellautomation.com) describes some important differences between solid state
equipment and hard-wired electromechanical devices. Because of this difference, and also because of
the wide variety of uses for solid state equipment, all persons responsible for applying this equipment
must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages
resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the
many variables and requirements associated with any particular installation, Rockwell Automation, Inc.
cannot assume responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits,
equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell

Environment and Enclosure
Follow these guidelines for environment and enclosure information for this
equipment.
ATTENTION
This equipment is intended for use in overvoltage Category II applications (as
defined in IEC 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 11. Without appropriate precautions, there may be difficulties

to conducted and radiated disturbances.
This equipment is supplied as enclosed equipment. It should not require
additional system enclosure when used in locations consistent with the
enclosure type ratings stated in the Specifications section of this publication.
Subsequent sections of this publication may contain additional information
regarding specific enclosure type ratings, beyond what this product provides,
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.
Prevent Electrostatic Discharge
Follow these guidelines when you handle this equipment.
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 potental 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.

4 ArmorPOINT I/O DeviceNet Adapters
About the Adapter
The ArmorPOINT I/O family of DeviceNet adapters ship with the adapter
and a terminating base to be used with the last I/O module on the backplane.
The sealed IP67 housing of these adapters requires no enclosure. Note that
environmental requirements other than IP67 may require an additional
appropriate housing. DeviceNet connectors are sealed M12 (micro) or M18
(mini) styles.

Mount the I/O Base
Mount the I/O base on a wall or panel, use the screw holes provided
in the adapter.
IMPORTANT
ATTENTION
ATTENTION
The ArmorPOINT I/O module must be mounted on a grounded metal
mounting plate or other conductive surface.
To comply with the CE Low Voltage Directive (LVD), all connected I/O must be
powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
This product is intended to be mounted to a well-grounded mounting surface
such as a metal panel. Additional grounding connections from the power
supply mounting tabs or DIN rail (if used) are not required unless the mounting
surface cannot be grounded. Refer to Industrial Automation Wiring and
Grounding Guidelines, Rockwell Automation publication 1770-4.1, for
additional information.

Install the mounting as follows:
1. Lay out the required points as shown in the drilling
dimension drawing.
2. Drill the necessary holes for M4 (#8) machine or self-tapping screws.
3. Mount the base using M4 (#8) screws.
4. Ground the system using the ground lug connection.
The ground lug connection is also a mounting hole.

Install the Adapter
Follow the instructions to install the adapter.
1. Using a bladed screwdriver, rotate the keyswitch on the mounting base
clockwise until the number 1 aligns with the notch in the base.
2. Position the module vertically above the mounting base.
The module bridges two bases.
3. Push the module down until it engages the latching mechanism.
You will hear a clicking sound when the module is properly engaged.
The locking mechanism locks the module to the base.

ArmorPOINT I/O DeviceNet Adapters 7
Remove the Adapter From the Mounting Base
Follow the instructions to remove the adapter from the mounting base.
1. Put a flat blade screwdriver into the slot of the orange latching
mechanism.
2. Push the screwdriver toward the I/O module to disengage the latch.
The module lifts up off the base.
3. Pull the module off the base.
Set the Network Address
Valid node addresses are 00…63.
Set the node address using either the rotary switches, RSNetWorx for
DeviceNet, DeviceNetManager, or another software configuration tool.
Setting the switches at any number from 64…99 allows the software to have
address control.
Each module is shipped with the switches set for node address 63. Remove the
caps on the front of the module to access the switches. The two switches are:
• X10 (most significant digit) – left side of module
• X1 (least significant digit) – right side of module
Network Node Example
This example shows
the network address
set at 63.
44316
To reset the node address, use a small blade screwdriver to rotate the switches.
Line up the small notch on the switch with the number setting you wish to use
and then cycle power.
The I/O adapter periodically reads the rotary switches. If the switches have
changed since the last reading and they no longer match the online address, a
Publication 1738-IN014D-EN-E - December 2010
8 ArmorPOINT I/O DeviceNet Adapters
minor fault occurs, which is indicated by a flashing red Adapter Status LED.
Settings of 64…99 cause the module to use the last valid node address stored
internally. Example: The last setting internally was 40. If a change is made to
68, and then you power up, the address will default to 40.
The module is equipped with AutoBaud detect. AutoBaud lets the module
read the settings already in use on your DeviceNet network and automatically
adjusts to follow those settings.
Wire the Adapter
Follow the wiring instructions for the ArmorPOINT I/O
DeviceNet adapters.
