Environment and Enclosure

Prevent Electrostatic Discharge

For additional information, refer to Industrial Automation Wiring and Grounding

Guidelines, publication 1770-4.1.

ATTENTION 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 (6562 feet) 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 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 publication 60529, as applicable, for

explanations of the degrees of protection provided by different types of enclosure.

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.

6ControlLogix ControlNet Interface Module

Publication 1756-IN607A-EN-P - February 2008

The ControlNet Interface Module and Redundant Media

Use the 1756-CN2 ControlLogix ControlNet series B module if

redundant media is not necessary. Applications requiring redundant

media must use the 1756-CN2R module.

Understanding Standalone and Redundant Control

You can use the 1756-CN2R series B modules for standalone or

redundant control. For standalone control, only one set of modules is

required. For redundant control, two ControlLogix chassis are

populated with identical pairs of modules called partners. The chassis

that performs active control is called the primary chassis and the

modules in the chassis are called primary modules. The other chassis

is called the secondary chassis and the modules in the chassis are

called secondary modules.

These installation instructions discuss both standalone and redundant

control; read them carefully to distinguish the procedures and

requirements for each type of control.

If you use redundant control, you must select the same ControlNet

network address for each set of partner modules (primary and

secondary). You must also place the partner modules in the same

corresponding slots in their respective redundant-control chassis

pair.

For more redundancy information, refer to the ControlLogix

Redundancy System User Manual, publication 1756-UM523F.

Set the Module’s Network Address Switches

Use a small screwdriver to set the module’s network address

switches. For modules in a standalone chassis, you must specify a

unique ControlNet network address. You can select an address of

01...99 for modules in a standalone chassis. Address 00 is an invalid

ControlNet address.

Reset the Module to the Original Factory Settings

To reset the module to its original settings and clear all keeper

information (see page 11), complete the following steps.

1. Remove power from the chassis.

2. Remove the module from the chassis.

IMPORTANT The following procedure instructs you to remove power from the chassis

before removing the module. This is only necessary if the module is in a

Class I, Division 2 hazardous location. For more information, see Install or

Remove the Module Under Power on page 18.
