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://www.ab.com/manuals/gi) 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.

Preface

What’s in This Chapter

Use this manual to plan and install a ControlNet Ex media system.

This manual describes the required components of an intrinsically-safe

cable system and how to plan for and install these required

components.

This manual targets the configurion of a ControlNet Ex system.

However, since a ControlNet Ex system and a ControlNet system can

be linked, it may be necessary to introduce and refer to concepts on

the ControlNet side of the network.

Some configurations on a standard ControlNet system may not be

possible within a ControlNet Ex configuration. Many of the installation

methods and equipment for the ControlNet Ex system is the same as

those available for the ControlNet system. However, some differences

do exist. As you use this manual, note these differences.

The following tables describe where specific information is found in

this manual.

Overview of the ControlNet Ex Media System

What This Chapter Contains

Use this chapter to familiarize yourself with the ControlNet Ex media

system. The following table describes what this chapter contains and

where to find specific information.

This system is an intrinsically-safe system specifically designed for use

in hazardous areas.

For Information On See Page

Understand the ControlNet Ex Media System 1-2

Understand ControlNet Ex Components 1-4

ControlNet Ex System Installation Requirements 1-9

TIP For information on installation requirements for

hazardous areas, refer to NFPA 70 (National Electrical

Code NEC), Article 500.

TIP This publication describes how to plan and install a

ControlNet Ex media system in a hazardous area.

Refer to the following publications for information

on how to plan and install a coax and fiber media

system in a non-hazardous environment:

•CNET-IN002, ControlNet Coax Media Planning

and Installation Manual

•CNET-IN001, ControlNet Fiber Media Planning

and Installation Manual

ATTENTION The ControlNet Ex media system cannot be used in a

safe environment after it has been exposed to signals

from a hazardous area.

1-2 Overview of the ControlNet Ex Media System

Understand the ControlNet

Ex Media System

The ControlNet Ex media system gives you the flexibility to design a

communication network for your particular application. To take full

advantage of this flexibility, spend sufficient time when you plan how

to install your network before you assemble any of the hardware.

For information on installing ControlNet media in a hazardous area,

refer to the ControlNet Coax Media Planning and Installation Manual,

publication CNET-IN002.

Use the following figures and term definitions to understand the

ControlNet Ex media system

Figure 1.1 ControlNet Coax to Fiber system for FLEX Ex

Term Means

Network •A collection of connected nodes

•A collection of nodes with unique addresses in the range of 1-99

•The connection paths between any pair of devices may include repeaters and bridges.

Segment •Trunk cable sections connected via taps with terminators at each end and with no

repeaters.

Trunk Cable •The bus or central part of a media system

Trunk Cable Section •A length of a cable between any two taps

Fiber Repeater Hub •Consists of a fiber repeater and fiber adapter

•The components reconstruct and retransmit all traffic on one fiber or coax segment

side to another coax or fiber segment side.

Tap •The connection between any device and the ControlNet Ex or ControlNet media

system
