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 liable for indirect or consequential damages 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.

Environment and Enclosure
			This equipment is intended for use in a Pollution Degree 2 industrial
ATTENTION
			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.

Prevent Electrostatic Discharge

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.

•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 1756-CNB and 1756-CNBR Series E Modules

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

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.

Publication 1756-IN604A-EN-P - February 2006

ControlLogix ControlNet Interface Module 7

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.

1786-TPYR, or1786 -TPYS(1) 1786-TP (temporary

network connections)

Small Screwdriver (optional)

(1)1786-TPS or 1786-TPYS taps recommended for network connections.

•Know the type of ControlNet network:

There are two types of scheduled traffic networks for ControlNet: single-keeper networks and multi-keeper networks.

Publication 1756-IN604A-EN-P - February 2006

ControlLogix ControlNet Interface Module 9

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

1756-CNB and 1756-CNBR	Major/Minor Revision	Keeper Type
A	1.xx	Single-keeper
B	2.xx	Multi-keeper
C	3.xx	Single-keeper
C	4.xx	Multi-keeper
D	5.xx	Multi-keeper
D	7.xx	Multi-keeper
E	10.xx	Multi-keeper
E	11.xx	Multi-keeper

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. 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; for modules in a redundant chassis, you must specify the same address for the secondary module that you specified for the corresponding primary module.

TIP

This module’s network address is 23.

You can select an address of 01 to 99 for modules in a standalone chassis or 01 to 98 for modules in redundant chassis. 00 is an invalid ControlNet network address.
