This second edition introduces and expands on the specialized terminology and concepts of data communications systems as applied to industry and manufacturing. It supplies technical personnel with the knowledge that they will need to face the challenge of understanding systems integration.
This reference is the first place to turn for information about all types of data communications systems. Written by noted best-selling author Gil Held, the third edition features new chapters on client/server systems, internetworking, and video conferencing, as well as thorough updates for all other chapters. Communications engineers and technicians designing all types of communications systems will find in-depth coverage of both the conceptual foundation and essential technology, including components, network design and configurations, transmission media, protocols, topologies, architectures, and future technology.

The objective of this book is to outline the best practice in designing, installing, commissioning and troubleshooting industrial data communications systems. In any given plant, factory or installation there are a myriad of different industrial communications standards used and the key to successful implementation is the degree to which the entire system integrates and works together. With so many different standards on the market today, the debate is not about what is the best - be it Foundation Fieldbus, Profibus, Devicenet or Industrial Ethernet but rather about selecting the most appropriate technologies and standards for a given application and then ensuring that best practice is followed in designing, installing and commissioning the data communications links to ensure they run fault-free. The industrial data communications systems in your plant underpin your entire operation. It is critical that you apply best practice in designing, installing and fixing any problems that may occur. This book distills all the tips and tricks with the benefit of many years of experience and gives the best proven practices to follow. The main steps in using today's communications technologies involve selecting the correct technology and standards for your plant based on your requirements; doing the design of the overall system; installing the cabling and then commissioning the system. Fiber Optic cabling is generally accepted as the best approach for physical communications but there are obviously areas where you will be forced to use copper wiring and, indeed, wireless communications. This book outlines the critical rules followed in installing the data communications physical transport media and then ensuring that the installation will be trouble-free for years to come. The important point to make is that with today’s wide range of protocols available, you only need to know how to select, install and maintain them in the most cost-effective manner for your plant or factory - knowledge of the minute details of the protocols is not necessary. An engineer's guide to communications systems using fiber optic cabling, copper cabling and wireless technology Covers: selection of technology and standards - system design - installation of equipment and cabling - commissioning and maintenance Crammed with practical techniques and know how - written by engineers for engineers
There are many data communications titles covering design, installation, etc, but almost none that specifically focus on industrial networks, which are an essential part of the day-to-day work of industrial control systems engineers, and the main focus of an increasingly large group of network specialists. The focus of this book makes it uniquely relevant to control engineers and network designers working in this area. The industrial application of networking is explored in terms of design, installation and troubleshooting, building the skills required to identify, prevent and fix common industrial data communications problems - both at the design stage and in the maintenance phase. The focus of this book is 'outside the box'. The emphasis goes beyond typical communications issues and theory to provide the necessary toolkit of knowledge to solve industrial communications problems covering RS-232, RS-485, Modbus, Fieldbus, DeviceNet, Ethernet and TCP/IP. The idea of the book is that in reading it you should be able to walk onto your plant, or facility, and troubleshoot and fix communications problems as quickly as possible. This book is the only title that addresses the nuts-and-bolts issues involved in design, installation and troubleshooting that are the day-to-day concern of engineers and network specialists working in industry. * Provides a unique focus on the industrial application of data networks * Emphasis goes beyond typical communications issues and theory to provide the necessary toolkit of knowledge to solve industrial communications problems * Provides the tools to allow engineers in various plants or facilities to troubleshoot and fix communications problems as quickly as possible
This book has evolved primarily from lecture notes for data communications courses taught at Georgia State University since 1969. Additional material was derived from seminar presentations that were made during this period as well as from consulting work. Teaching data communications in the College of Business Administration influenced the point of view of this material, giving it a semitechnical orientation. This point of view has been extended to the prepara tion of this book. Only those technical details were included which, it was felt, would lead the student to a better understanding of the subject. References are provided for those who desire further information in particular areas. The reader for whom this book is intended is the nontechnical person who has some knowledge of computer technology and who wishes to extend that knowledge to the field of data communications. The two key points stressed in this book are terminology and concepts. The objectives of this book are to enable the student: 1. To read articles in the field of data communications with an understand ing of their content. 2. To be able to engage in knowledgeable discussions with communica tions engineers on the subject of data communications. 3. To design and implement the hardware aspects of applications using data communications. The software that would be involved is beyond the scope of this book except where protocols are considered. v vi Preface 4. To effectively evaluate proposals for the implementation of data com munications systems.
