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, for additional

installation requirements, Allen-Bradley publication 1770-4.1.

•NEMA Standards publication 250 and IEC 60529, as applicable, for

explanations of the degrees of protection provided by different types of

enclosure.

North American Hazardous Location Approval

The following information applies when

operating this equipment in hazardous

locations.

Informations sur l’utilisation de cet

équipement en environnements dangereux.

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.

Prevent Electrostatic Discharge

About the Module

The module provides EtherNet/IP connectivity. Use the tap to support

linear, star, and device-level ring (DLR) topologies. The module is configured

by default to support linear and star topologies. When setting up a DLR,

follow the steps in the Use the Module in a Device-level Ring (DLR) Network

section on page 15 to avoid adversely impacting your network.

Refer to the EtherNet/IP Ring Topology Application Guide,

publication ENET-AP005, for information on setting up EtherNet/IP

network topologies.

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.

Determine Module Slot Location

Install the module in any slot in the ControlLogix chassis. You can install

multiple 1756-EN2TR or 1756-EN3TR modules in the same chassis. The

following figure shows chassis slot numbering in a 4-slot chassis. Slot 0 is the

first slot and is always the leftmost slot in the rack.

Set the Network Address

The module is shipped 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.

• Use Rockwell Automation RSLinx Classic or RSLogix 5000 software.

Publication 1756-IN612B-EN-P - December 2009

Use the Rotary Switches

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 switches). 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, nor does it use any Domain

Name System when using the rotary switch settings.

1. 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.

2. After cycling power with the switches set to 888, remove the module

and set the switches to their final value.

The software configuration determines the IP address when you set

the rotary switches to:

•a value other than 888.

•the valid IP address values 001…254.

Use a DHCP/BOOTP Server

If you do not have a large computer that can act as a boot server, download

our DHCP/BOOTP software so you can use a personal computer as a

DHCP/BOOTP server.

To set the network address by using the Rockwell Automation

DHCP/BOOTP server, follow these steps.

1. Access the DHCP/BOOTP utility at

http://www.ab.com/networks/ethernet/bootp.html.

2. Download the version 2.3.2 DHCP/BOOTP utility.

3. Extract the zipped files to a temporary directory.

4. In the temporary directory, double-click setup.exe to install the

DHCP/BOOTP utility.

5. Run the utility.

6. Refer to the following chart, which describes what happens next,

depending on whether DHCP/BOOTP is enabled on the module.

If DHCP/BOOTP is The module

Enabled Asks for an address from a DHCP/BOOTP server. The server

also assigns other Transport Control Protocol (TCP) parameters.

Not enabled Uses the IP address (along with other TCP configurable

parameters) stored in nonvolatile memory.
