Important User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://literature.rockwellautomation.com/) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable. In no event will Rockwell Automation, Inc. be responsible or liab le for indir ect or consequen tial damage s resulting from the use or application of this equipment. The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams. No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual. Reproduction of the contents of th is manual, in whole or in part, without writ t en p e r mission of Rockwell Automation, Inc., is prohibited. Throughout this manual, when necessary, we use notes to make you aware of safety considerations.

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 Divisi on 2 Groups A, B, C, D, Hazardous Locations and nonhazardous locations only. Each product is supplied with markings on the rating nameplate indic ating 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

Publication

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.

1756-IN602A-EN-P - November 2005

Informations sur l'utilisation de cet équipement en environnements dangereux:

Les produits marqués “CL I, DIV 2, GP A, B, C, D” ne conviennent qu'à une utilisation en environnements de Classe I Division 2 Groupes A, B, C, D dangereux et non dangereux. Chaque produit est livré avec des marquages sur sa plaque d'identification qui indiquent le code de température pour les environnements dangereux. Lorsque plusieurs produits sont combinés dans un système, le code de température le plus défavorable (code de température le plus faible) peut être utilisé pour déterminer le code de température global du système. Les combinaisons d'équipements dans le système sont sujettes à inspection par les autorités locales qualifiées au moment de l'installation.

AVERTISSEMEN

RISQUE D'EXPLOSION Couper le courant ou s'assurer

que l'environnement est classé non dangereux avant de débrancher l'équipement.

Couper le courant ou s'assurer que l'environnement est classé non dangereux avant de débrancher les connecteurs. Fixer tous les connecteurs externes reliés à cet équipement à l'aide de vis, loquets coulissants, connecteurs filetés ou autres moyens fournis avec ce produit.

La substitution de composants peut rendre cet équipement inadapté à une utilisation en environnement de Classe I, Division 2.

S'assurer que l'environnement est classé non dangereux avant de changer les piles.

Environment and Enclosure

ControlLogix ControlNet Bridge Module 5

ATTENTIO

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.

NOTE: 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 Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley publication 1770-4.1, for additional installation requirements pertaining to this equipment.

Preventing Electrostatic Discharge

ATTENTIO

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.

For additional information, refer to Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1.

About the ControlLogix ControlNet Bridge Module

We designed the enhanced ControlLogix ControlNet module for applications that require higher capacity, and we recommend that you use this module with ControlLogix controllers to:

• expand systems for twice as much I/O control.

• effectively double the amount of Produce/Consume tags that

can be transferred between controllers.

• speed up existing applications to run faster.

Use the 1756-CN2 ControlLogix ControlNet module for stand-alone applications only. Applications requiring controller redundancy must use the 1756-CNB module.

ControlLogix ControlNet Bridge Module 7

Before You Begin

Before you install the module, make sure you:

• know how to handle the module (see Preventing Electrostatic Discharge).

• know the type of ControlNet network.

There are two types of scheduled traffic networks for ControlNet: single-keeper networks and multi-keeper networks. The 1756-CN2 and 1756-CN2R bridges are multi-keeper capable.

You must match the keeper to the type of network. Refer to the ControlNet Modules in Logix5000 Control Systems User Manual, publication CNET-UM001, for more information.

Set the Module’s Network Address Switches

Use your fingers or 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 to 99 for modules in a standalone chassis. Note that 00 is an invalid ControlNet address.

This module’s network address is 23.

Prepare the Chassis for Module Installation

Before you install the 1756-CN2 module, you must install and connect a ControlLogix chassis and power supply. A 4-slot chassis with a power supply is shown below.

Determine Module Slot Location

This 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 (the first slot to the right of the power supply). You can use any size ControlLogix chassis and install the module in any slot. You can also install multiple bridge modules in the same chassis. You can install as many modules as your power supply can accommodate (that is, the number for which the power supply is rated).
