Environment and Enclosure

ATTENTION This equipment is intended for use in a Pollution Degree 2 industrial

environment,inovervoltageCategoryIIapplications(asdefinedinIEC

publication60664-1),ataltitudesupto2000meterswithoutderating.

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.

For additional information, refer to Industrial Automation Wiring and

Grounding Guidelines, publication 1770-4.1.

About the 1756-CNB and 1756-CNBR Series E Modules

The 1756-CNB and 1756-CNBR Series E modules work for all nonredundant

ControlLogix applications.

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.

•If available, use a static-safe workstation.

•Whennot inuse, storethe equipmentinappropriatestatic-safe

packaging.

IMPORTANT Only the 1756-CNB and 1756-CNBR, Series D modules are

supported in ControlLogix Redundancy releases 8, 11, 13, and 15.

After a firmware upgrade to version 11.xx, Series E will be

supported in ControlLogix Redundancy release 15 or later.

You cannot upgrade a Series D module to a Series E module.

ControlLogix ControlNet Interface Module 7

Publication 1756-IN604A-EN-P - February 2006

Understand Standalone and Redundant Control

You can use the 1756-CNB and 1756-CNBR Series E modules as standalone

or in firmware version 11.xx as 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.

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

network address for each set of partner modules. You must also

place the partner modules in the same corresponding slots in their

respective redundant control chassis pair.

Before You Begin

Before you install the module you need to make sure you:

•Know how to handle the module.

Refer to the section Prevent Electrostatic Discharge.

•Have all of the necessary components:

•Know the type of ControlNet network:

There are two types of scheduled traffic networks for ControlNet:

single-keeper networks and multi-keeper networks.

All 1756-CNB and 1756-CNBR modules are keeper-capable, as listed.

You must match the keeper to the type of network, or upgrade the

firmware of the module at MAC ID 01 to be multi-keeper capable.
