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

About the EtherNet/IP Bridge Module
Configure and use the 1756-EN2TXT module as you would a
traditional 1756-EN2T module. For more information about

IMPORTANT
About ControlLogix-XT Systems
The ControlLogix-XT products include control and communication
system components that, when used with FLEX I/O-XT products,
provide a complete control system solution that can be used in
environments where temperatures range from -20...70 °C
(-4...158 °F).
When used independently, the ControlLogix-XT system can withstand
ironments where the temperature ranges from -25...70 °C
env
(-13...158 °F).
ControlLogix-XT with Traditional ControlLogix Components
ControlLogix-XT system components are rated for extreme
environmental conditions only when used properly with other
Logix-XT system components. The use of ControlLogix-XT components
with traditional ControlLogix system components nullifies
extreme-environment ratings.
If a ControlLogix-XT module is used with traditional ControlLogix products,
that is, ControlLogix products not designed for extreme environments, the
ControlLogix-XT module can withstand only the environments specified for
the traditional ControlLogix version of the module. For example, if a
1756-EN2TXT module is used in a standard 1756-A10 chassis, the
1756-EN2TXT module can withstand only the environment specified for the
traditional 1756-EN2T module.
The ControlLogix-XT system components are designed to meet the same
greater operational and environmental requirements as traditional
and
ControlLogix products.
When a ControlLogix-XT component is

specifications of the traditional ControlLogix component apply.

Set the Network Address
The module ships with the rotary switches set to 999 and BOOTP

• Use Rockwell Automation’s RSLinx or RSLogix 5000 software.

Reset the Module to Initial Settings
To reset the module to its initial out-of-the-box settings, reset the
switches to 888 and cycle power.
Do not use the 888 switch setting during normal module operation.
After cycling power with the switches set to 888, remove the module

Install the Module
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.
Complete these steps to install the module.
1. Align the circuit board with top and bottom guides in the

2. Slide the module into the chassis.
Make sure the module backplane connector properly connects
to the chassis backplane. The module is properly installed

Connect the Module to the EtherNet/IP Network
If you connect or disconnect the communication 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.
Attach the RJ45 connector to the Ethernet port on the bottom of the
module as shown.
We recommend connecting the module to the network via a 100 MB
Ethernet switch, which will reduce collisions and lost packets and increase
network bandwidth. For detailed EtherNet/IP connection information, see

Connect to the Module Via the USB Port
The USB port is intended for only for temporary local programming purposes
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.
Components Required for USB Connection
The EtherNet/IP module has a USB device port that uses a Type B
receptacle. The port is USB 1.1-compatible and runs at 12 Mbps. To
the USB port with this 1756-EN2TXT module, you must have
use
RSLinx software, version 2.55 or later, installed on your workstation.
Connect the USB Cable
USB cable length must be less than 3 m (9.84 ft) and must not contain hubs.
Use a USB cable to connect your computer to the USB port. The
connection lets you download programs to controllers and configure
Ethernet modules directly from your computer.
If your installation of RSLinx software has not had a USB driver set
you will be prompted to install the required software. For more
