* Essential reading for data acquisition and control professionals as SCADA systems have permeated modern plants and factories * Covers the fundamentals of SCADA systems hardware, software and the communications systems that connect SCADA operator stations * Provides readers with the tools to design their next SCADA system more effectively and to draw on the latest technologies This is a comprehensive book covering the essentials of SCADA (Supervisory Control and Data Acquisition) systems. A SCADA system is a computer system for gathering and analyzing real time data. SCADA systems are used to monitor and control a plant or equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining and transportation. This title covers the fundamentals of SCADA systems hardware, software and the communications systems (such as Ethernet and TCP/IP) that connect SCADA operator stations. It provides you with the tools to design your next SCADA system more effectively and to draw on the latest technologies. This book provides you with the knowledge to analyze, specify and debug SCADA systems in the instrumentation and control environment. A SCADA system gathers information, such as where a leak on a pipeline has occurred, transfers the information back to a central site, alerting the home station that the leak has occurred, carrying out necessary analysis and control, such as determining if the leak is critical, and displaying the information in a logical and organized fashion. SCADA systems can be relatively simple, such as one that monitors environmental conditions of a small office building, or incredibly complex, such as a system that monitors all the activity in a nuclear power plant or the activity of a municipal water system.David Bailey BEng is the author of 'Practical SCADA for Industry (IDC Technology)', published 2003 under ISBN 9780750658058 and ISBN 0750658053.
