About This User Manual

What this Preface Contains

This preface describes how to use this manual. The following table

describes what this preface contains and where to find specific

information.

Who Should Use

This Manual

This manual is intended for control engineers and technicians who are

installing, programming, and maintaining a control system that

communicates on an Ethernet network through a 1756-ENET/B

module.

We assume you have a good understanding of Ethernet and the

(TCP/IP) protocol. This user manual contains a brief description of

Ethernet and TCP/IP in Chapter 3. For detailed information on TCP/IP

protocol and networking in general, see the following publications:

•Comer, Douglas E. Internetworking with TCP-IP, Volume 1:

Protocols and Architecture, 2nd ed. Englewood Cliffs, N.J.:

Prentice-Hall, 1995. ISBN 0-13-216987-8.

P-2 About This User Manual

Common Techniques

Used in This Manual

The following conventions are used throughout this manual:

•Bulleted lists provide information, not procedural steps.

•Numbered lists provide sequential steps.

•Information in bold contained within text identifies menu

windows, or screen options, screen names and areas of the

screen, such as dialog boxes, status bars, radio buttons and

parameters.

How To Use This Manual

This manual provides an overview of the 1756-ENET/B module, as

well as general information about Ethernet. It describes how to install

and configure the module, and provides three example applications

showing how to use the module to communicate over Ethernet.

The example applications are intended as building blocks to help you

get your own network up and running. We recommend that you set

up and run the example applications and use them as a guide for

setting up your own system.

TIP This symbol identifies helpful tips.

A definition box defines terms that may be

unfamiliar to you.

Screen captures are pictures of the software’s

actual screens. The names of screen buttons and

fields are often in bold in the text of a

procedure. Pictures of keys represent the actual

keys you press.

This is a definition

box. When a word is

bold within the text

of a paragraph, a

definition box will

appear in the left

margin to further

define the text.
