North American Hazardous Location Approval

The following information applies
when operating this equipment in
hazardous locations.

Products marked "CL I, DIV 2, GP A, B, C, D" are
suitable for use in Class I Division 2 Groups A, B, C,
D, Hazardous Locations and nonhazardous
locations only. Each product is supplied with
markings on the rating nameplate indicating the
hazardous location temperature code. When
combining products within a system, the most
adverse temperature code (lowest "T" number) may
be used to help determine the overall temperature
code of the system. Combinations of equipment in
your system are subject to investigation by the
local Authority Having Jurisdiction at the time of
installation.

WARNING:
Explosion Hazard -

•Do not disconnect equipment
unless power has been removed
or the area is known to be
nonhazardous.

•Do not disconnect connections to
this equipment unless power has
been removed or the area is
known to be nonhazardous.
Secure any external connections
that mate to this equipment by
using screws, sliding latches,
threaded connectors, or other
means provided with this product.

•Substitution of components may
impair suitability for Class I,
Division 2.

•If this product contains batteries,
they must only be changed in an
area known to be nonhazardous.

Environment and Enclosure

ATTENTION: This equipment is intended for use in a Pollution

Degree 2 industrial environment, 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 with electromagnetic
compatibility in residential and other environments due to
conducted and radiated disturbances.

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 enclosure must have suitable
flame-retardant properties to prevent or minimize the spread of
flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or
equivalent) if non-metallic. 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.

In addition to this publication, see:

• Industrial Automation Wiring and Grounding Guidelines, Rockwell
Automation publication 1770-4.1
requirements.

• NEMA Standard 250 and IEC 60529, as applicable, for
explanations of the degrees of protection provided by different
types of enclosure.

, for additional installation

ControlLogix EtherNet/IP Module 5

ATTENTION: 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.

• Use a static-safe workstation, if available.

• Store the equipment in appropriate static-safe packaging when

not in use.

ControlLogix EtherNet/IP Module 9

Set the Network Address

The module ships with the rotary switches set to 999 and BOOTP enabled. You
can set the network Internet Protocol (IP) address three ways.

• Use the rotary switches on the top of the module.

• Use a BOOTP server or Dynamic Host Configuration Protocol

(DHCP) server, such as Rockwell Automation BOOTP/DHCP.

• Use the Rockwell Automation RSLinx or RSLogix 5000 software.

The module reads the rotary switches first to determine if they are set to a valid
number for the last portion of the IP address. Valid numbers range from
001…254. When the switches are set to a valid number, the module’s IP address
is 192.168.1.xxx (where xxx represents the number set on the swBOOTPitches).
The module’s subnet mask is 255.255.255.0 and the gateway address is set to

0.0.0.0. The module does not have a host name assigned, or use any Domain
Name System when using the rotary switch settings.

Rockwell Automation Publication 1756-IN606B-EN-P - April 2010

10 ControlLogix EtherNet/IP Module

To reset the module to its initial out-of-the-box settings, reset the switches to
888 and cycle power.

IMPORTANT

Do not use the 888 switch setting during normal module operation.

After cycling power with the switches set to 888, remove the module and set the
switches to their final value. When you set the rotary switches to a value other
than 888, or to the valid IP address values 001…254, the software configuration
determines the IP address.

the chassis backplane.

TIP

Rockwell Automation Publication 1756-IN606B-EN-P - April 2010

The module is properly installed when it is flush with the power supply or
other installed modules.

ControlLogix EtherNet/IP Module 13

Connect the Module to the EtherNet/IP Network

Attach the LC2 fiber cable to the Ethernet port on the bottom of the module as
shown.

ATTENTION: Do not look directly into the optical port. Under
certain conditions, viewing the optical port may expose the eye to
hazard. When viewed under some conditions, the optical port may
expose the eye beyond the maximum permissible exposure
recommendations.

14 ControlLogix EtherNet/IP Module

Program the Module via the USB Port

WARNING: The USB port is intended for temporary local

programming purposes only and is not intended for permanent
connection. If you connect or disconnect the USB cable with power
applied to this module or any device on the USB 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. A Samtec Inc. RSP-119350 USB
cable is required to maintain hazardous location certifications.

ATTENTION:

• The USB port is designed for a temporary connection only.

• The USB cable is not to exceed 3.0 m (9.84 ft) and must not

contain hubs.

• To maintain product certification integrity, you must use SAMTEC
cable, part number RSP-119350.

The module has a USB device port that uses a type B receptacle. Use a USB cable
to connect your computer to the USB port. To use the USB port, you must have
RSLinx software, version 2.51 or later, installed on your computer. The
connection lets you download programs to controllers and configure Ethernet
modules directly from your computer.

Rockwell Automation Publication 1756-IN606B-EN-P - April 2010

ControlLogix EtherNet/IP Module 15

Configure the Module

Follow these steps to configure the module.

1. In RSLogix 5000 software, from the Controller Organizer, select New
Module.

2. Select the module you want to configure.

When power is applied to the module, the alphanumeric display should cycle
through these states:

• TEST

• PA SS

• OK

• REV x.x

where x.x is the module’s firmware revision.

The display then alternates between OK and the module’s EtherNet/IP address.

Install or Remove the Module Under Power

You can install or remove this module while chassis power is applied.

WARNING: When you insert or remove the module while
backplane power is on, 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. Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating connector. Worn
contacts may create electrical resistance that can affect module
operation.

1. Push on upper and lower module tabs to disengage them.

2. Slide the module out of the chassis.

IMPORTANT

If you want to replace an existing module with an identical
one, and you want to resume identical system operation, you
must install the new module in the same slot.
