TABLE OF CONTENTS CTA 4/2003 ENGINEER'S NOTEBOOK 48 Ultrasonic sensors for control systems By Victor Zhdankin Continuation of the series of articles on ultrasonic sensors. The author describes problems with these sensors and ways to improve their effectiveness in practical applications, citing the capabilities of the sensors from Pepperl+Fuchs and examples of how they are being used. 64 Principles of ensuring electrical compatibility of measurement devices By Aleksandr Garmanov 74 Calibration equipment By Aleksandr Tokarev TRAINING 76 PROSOFT Training Center By Maxim Ananskikh and Anna Dolgova EXHIBITIONS, CONFERENCES, SEMINARS 80 MAKS: Achievements in the air and on Earth Advantech days in Russia Road show: seminars on industrial automation on the banks of the Volga Intel's «autumn offensive» ReportWorX links enterprise control systems and automated process control systems EMPLOYMENT 85 SHOWROOM 87 SYSTEM INTEGRATION PROJECTS IN BRIEF 92 News 51, 86 REVIEW/ Hardware 6 Singleboard computers for built-in systems By Konstantin Kruglyak This article examines the criteria for selecting off-the-shelf hardware for creating computing systems in built-in applications. The author reviews the current standards in this space, and the article includes examples from the companies Advantech, Diamond Systems, Lippert, Fastwel and Octagon Systems. SYSTEM INTEGRATION/ Electric Power Industry 18 Yantar energy management control system By Andrey Fukalov In this article, the author describes the development and implemen- tation of an energy management control system for shops at the Urals Electrochemical Plant. The article describes in detail the structure of the system and the hardware and software involved. SYSTEM INTEGRATION/ Chemical Industry 24 Automating the industrial carbon production process By Dmitriy Antropov, Timofey Petrov, Vasiliy Linnik and Sergey Frolov This article examines various issues involved in developing an auto- mated process control system for the production of industrial car- bon, using as an example the system developed under contract for the Nizhnekamsk Industrial Carbon Plant. This system combines robust capabilities with a relatively low cost of ownership. The article devotes particular attention to hardware redundancy issues. DEVELOPMENT/ Oil & Gas Industry 30 Upgrading the distributed control system for a gas pipeline By Victor Perminov, Anatoliy Yakovlev, Victor Chakov, Victor Fadeyev and Yurii Troshev In this article, the authors address the issues involved in using a PC-compatible controller to upgrade the distributed control system for a gas pipeline. HARDWARE/ Industrial Controllers 38 Local automation devices. Microcontrollers. By Aleksei Barmin This article is devoted to technology that can be used to address relatively simple automation problems. The author uses practical examples to illustrate the broad applicability of the LOGO! logic modules from Siemens. HARDWARE/ Modems 44 New technology for continuous data transmission By Nikolay Zhilenkov The author explains the primary advantages of using GPRS technology in automated process control systems, describing the popular MC35 Terminal series of GPRS modems, which were designed for industrial applications.
