applications (as defined in IEC publication 60664-1), at

altitudes up to 2000 m eters w ithout derating.

This equipm ent is considered G roup 1, Class A industrial

equipm ent according to IEC/CISPR Publication 11.

W ithout appropriate precautions, there m ay be potential

difficulties ensuring electrom agnetic com patibility in otherenvironm ents due to conducted as w ell as radiated

disturbance.

This equipm ent is supplied as open-type equipm ent. It

m ust be m ounted w ithin an enclosure that is suitably

designed for those specific environm ental conditions that

w ill be present and appropriately designed to prevent

personal injury resulting from accessibility to live parts.The interior of the enclosure m ust be accessible only by

the use of a tool. Subsequent sections of this publication

m ay contain additional inform ation regarding specific

enclosure type ratings that are required to com ply w ith

certain product safety certifications.

N O TE: See N EM A 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 w ell as Industrial Autom ation W iring and

About the ControlLogix ControlNet Bridge Module

W e designed the enhanced ControlLogix C ontrolN et m odule for

applications that require higher capacity, and w e recom m end that

you use this m odule w ith ControlLogix controllers to:

• expand system s for tw ice as m uch I/O control.

• effectively double the am ount of Produce/Consum e tags that

can be transferred betw een controllers.

• speed up existing applications to run faster.

U se the 1756-CN 2 ControlLogix ControlN et m odule for stand-alone

applications only. Applications requiring controller redundancy m ust

use the 1756-CN B m odule.

ATTENTION This equipm ent is sensitive to electrostatic discharge,w hich can cause internal dam age and affect norm al

operation. Follow these guidelines w hen you handle this

equipm ent:

• Touch a grounded object to discharge potential static.

• W ear an approved grounding w riststrap.

• D o not touch connectors or pins on com ponent

boards.

• D o not touch circuit com ponents inside the

equipm ent.

• If available, use a static-safe w orkstation.

• W hen not in use, store the equipm ent in appropriate

static-safe packaging.

Before You Begin

Before you install the m odule, m ake sure you:

• know how to handle the m odule (see Preventing Electrostatic

D ischarge).

• know the type of ControlN et netw ork.

There are tw o types of scheduled traffic netw orks for

ControlN et: single-keeper netw orks and m ulti-keeper

netw orks. The 1756-CN 2 and 1756-CN 2R bridges are

m ulti-keeper capable.

You m ust m atch the keeper to the type of netw ork. Refer to

the ControlN et M odules in Logix5000 C ontrol System s U ser

M anual, publication CN ET-U M 001, for m ore inform ation.

specify a unique ControlN et netw ork address. You can select an

address of 01 to 99 for m odules in a standalone chassis. N ote that 00

is an invalid ControlN et address.

Prepare the Chassis for Module Installation

Before you install the 1756-CN 2 m odule, you m ust install and connect

Install the Module

1 . Align the circuit board w ith top and bottom guides in thechassis.

2. Slide the m odule into the chassis.

M ake sure the m odule backplane connector properly connects

to the chassis backplane.

The m odule is properly installed w hen it is flush w ith the pow er

supply or other installed m odules.

ATTENTION D o not force the m odule into the backplane connector. If

you cannot seat the m odule w ith firm pressure, check the

alignm ent. Forcing the m odule into the chassis can

dam age the backplane connector or the m odule.

Connect the Module to the Network

You can connect the m odule to the ControlN et netw ork by using a

tap (1786-TPR, 1786-TPS, 1786-TPY R, 1786-TPY S) or a netw ork

access cable (1786-CP).

This figure show s an exam ple ControlN et netw ork using redundantm edia.

W hen connecting the bridge m odule to a ControlN et netw ork, youshould also refer to this docum entation:

Connect to t he Net w ork Using a Tap

Follow these steps to connect the m odule to the netw ork w ith a tap.

1 . Rem ove and save the dust caps from the ControlN et taps.

2. Connect the tap’s straight or right-angle connector to the

m odule’s BN C connector.

TIP For netw ork connections w e recom m end taps w ith a

straight connector (1786-TPS or 1786-TPY S) because of

the location of the B N C connectors on the bottom of them odule.

ATTENTION D o not allow any m etal portions of the tap to contact any

conductive m aterial. If you disconnect the tap from the

m odule, place the dust cap back on the straight or

right-angle connector to prevent the connector from

accidentally contacting a m etallic grounded surface.

You can install or rem ove the m odule w hile chassis pow er is applied

if you observe these precautions.

Troubleshoot the Modules

The m odules have these diagnostic indicators:

WARNING W hen you insert or rem ove the m odule w hile backplane

pow er is on, an electrical arc can occur. This could cause

an explosion in hazardous location installations.

Be sure that pow er is rem oved or the area is

nonhazardous before proceeding. Repeated electrical

arcing causes excessive w ear to contacts on both the

m odule and its m ating connector. W orn contacts m ay

create electrical resistance that can affect m odule

operation.
