Important User Information
Because of the variety of uses for the products described in this publication,
those responsible for the application and use of these products must satisfy
themselves that all necessary steps have been taken to assure that each
application and use meets all performance and safety requirements, including
any applicable laws, regulations, codes and standards. In no event will
Rockwell Automation be responsible or liable for indirect or consequential
damage resulting from the use or application of these products.
Any illustrations, charts, sample programs, and layout examples shown in this
publication are intended solely for purposes of example. Since there are many
variables and requirements associated with any particular installation,
Rockwell Automation does not assume responsibility or liability (to include

Environment and Enclosure
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.
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 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.
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 ("Industrial Automation Wiring and Grounding
Guidelines"), for additional installation requirements
pertaining to this equipment.

ATTENTION
!
Preventing Electrostatic Discharge
This equipment is sensitive to electrostatic discharge,
which 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 wriststrap.
•Do not touch connectors or pins on component
boards.
•Do not touch circuit components inside the
equipment.
•If available, use a static-safe workstation.
•When not in use, store the equipment in appropriate
static-safe packaging.
ATTENTION
!
POINT I/O is grounded through the DIN rail to chassis
ground. Use zinc-plated, yellow-chromated steel DIN rail
to assure proper grounding. Using other DIN rail
materials (e.g. aluminum, plastic, etc.) which can corrode,
oxidize or are poor conductors, can result in improper or
intermittent platform grounding.
WARNING
!
When you connect or disconnect the Removable
Terminal Block (RTB) with field side power applied, an
electrical arc can occur. This could cause an explosion in
hazardous location installations.
Be sure that power is removed or the area is
nonhazardous before proceeding.

Publication 1734-IN590A-EN-P - March 2003
Installing the EtherNet/IP Adapter
To install the adapter on the DIN rail prior to installing other base units,
proceed as follows.
1. Position the adapter vertically above the DIN rail.
2. Press down firmly to install the adapter on the DIN rail. The locking
mechanism will lock the adapter to the DIN rail.
3. Set the node address on the node address thumbwheel.
4. Slide the safety end cap up to remove. This exposes the backplane and
power interconnections.
WARNING
!
If you connect or disconnect the EtherNet cable with
power applied to this module or any device on the
network, an electrical arc can occur. This could cause an
explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous
before proceeding.
ATTENTION
!
Do not discard the end cap. Use this end cap to cover the
exposed interconnections on the last mounting base on
the DIN rail. Failure to do so could result in equipment
damage or injury from electric shock.

POINT I/O EtherNet/IP Adapter 7
Publication 1734-IN590A-EN-P - March 2003
Setting the Network Address
You can set the network Internet Protocol (IP) address 3 different ways:
1. using the thumbwheel switches located on the module
2. using a Dynamic Host Configuration Protocol (DHCP) server, such
as Rockwell Automation BootP/DHCP
3. retrieving the IP address from nonvolatile memory.
The adapter reads the thumbwheel switches first to determine if the switches
are set to a valid number. You set the node address using the 3-position
thumbwheel switch. Press either the + or - buttons to change the number.
Valid settings range from 001 to 254. When the switches are set to a valid
number, the adapter’s IP address will be 192.168.1.xxx (where xxx represents
the number set on the switches). The adapter’s subnet mask will be
255.255.255.0 and the gateway address is set to 0.0.0.0. The adapter will not
have a host name assigned, or use any Domain Name System when using the
thumbwheel settings.
If the switches are set to an invalid number (i.e. 000 or a value greater than
254), the adapter checks to see if DHCP is enabled. If DHCP is enabled, the
adapter asks for an address from a DHCP server. The DHCP server will also
assign other Transport Control Protocol (TCP) parameters.
If DHCP is not enabled, the adapter will use the IP address (along with other
TCP configurable parameters) stored in nonvolatile memory.

Manual, for more information.

Installing a Replacement EtherNet/IP Adapter to an Existing System
1. Remove the existing adapter from the DIN rail as follows:
a. Disconnect the EtherNet connector from the adapter.
b. Pull up on the RTB removal handle to remove the terminal block.
c. Remove the adjacent module from its base.
d. Use a small bladed screwdriver to rotate the DIN rail locking
screw to a vertical position. This releases the locking mechanism.
e. Lift straight up to remove.
2. Slide the safety end cap up to remove. This exposes the backplane and
power connections.
3. Position the replacement adapter vertically above the DIN rail. (Make
certain the DIN rail lock is in the horizontal position.) Slide the
adapter down, allowing the interlocking side pieces to engage the
adjacent module.
4. Press firmly to seat the adapter on the DIN rail. The adapter locking
mechanism will snap into place.
5. Set the node address on the node address thumbwheel.
6. Insert the end of the terminal block (RTB) opposite the handle into
the base unit. This end has a curved section that engages with the
wiring base.
7. Rotate the terminal block into the wiring base until it locks itself into
place.
8. Replace the adjacent module in its base.
9. Reconnect the Ethernet cable to the adapter.
ATTENTION
!
You must use Series C POINT I/O modules with the
1734-AENT adapter. Series A or B POINT I/O modules
will not work with this adapter.
