TABLE OF CONTENTS CTA 2/2003 46 System for collecting and displaying information using OPC and Internet technologies By Gleb Batalin and Vladimir Vasyutinskiy The authors detail their experience building the eXtenderOPC hierarchical system for collecting and displaying information using GENESIS32 SCADA. As an example of an implementation site, the article examines the oil-metering unit at Sibnefteprovod, which is a division of Transneft. The piece demonstrates the flexibility and new capabilities of the system thanks to the use of OPC and Internet technologies. DEVELOPMENT/ Oil & Gas Industry 52 Portable radiometer for measuring oil pollution in bodies of water By Vladimir Birulchik, Aleksandr Rynin and Mikhail Sovetkin This article devotes particular attention to the physical principles of the operation a polarization radiometer, as well as to the issue of selecting components for the unit in the design stage with consideration of the working conditions in regions of Western Siberia and the high requirements for the unit's reliability. The authors examine possibilities for expanding the number of solutions for the measurement challenge. DEVELOPMENT/ Utilities 60 Automated system for controlling a water screen By Vyacheslav Belozyorov, Nikolay Berdnikov, Yevgeniy Vinogradnyi, Andrey Kokhanovskiy, Aleksandr Latvis, Dmitriy Lebedev, Yurii Pankratov, Aleksandr Smirnov and Aleksandr Farafonov The authors describe the development of an automated system for controlling a water screen at a holding storehouse for liquid chlorine at the Severnaya Water Station in St. Petersburg. The article devotes particular attention to the issues of how to ensure high reliability and the necessary level of safety in the system. ENGINEER'S NOTEBOOK 66 Shield casings for electronic devices By Vladimir Belomyttsev 72 Intrinsic safety shunt-diode Zener barriers: selection criteria and application By Victor Zhdankin ENGINEER'S NOTEBOOK/ Questions & Answers 86 Schematic diagram for the NLP65-series AC/DC universal input switch-mode power supplies By Victor Zhdankin SHOWROOM 88 SYSTEM INTEGRATION PROJECTS IN BRIEF 93 News 44, 71, 85, 87 SYSTEM INTEGRATION/ Utilities 6 Remote site monitoring and control system By Valeriy Plyushchayev, Lyudmila Grosheva, Vladimir Merzlyakov, Sergey Perevezentsev, Andrey Zuyev and Aleksandr Pakhomov This article examines a system for remote site monitoring and control built for a network of heating stations in Kaliningrad. The authors describe the system's structure and its functional capabilities, and they cite certain details regarding the application of cellular communications channels and microcontrollers from Advantech. SYSTEM INTEGRATION/ Energy 16 Control system for a steam heat-recovery boiler By Aleksei Pshenitsyn The author discusses an automated process control system for a steam heat-recovery boiler. The system was built using an IBM PC-compatible industrial controller, and it was implemented at the Krasnokamsk Pulp and Paper Mill. SYSTEM INTEGRATION/ Glassmaking Industry 20 Controlling the glass melting process using the GENESIS32 suite By Sergey Zelenin and Nikolay Moskalyov This article was prepared based on the experience of creating a system for controlling a glass-melting furnace. The authors explain the reasons for using a system developed in-house based on integrating highly reliable hardware, and they describe the technological process, present a detailed electrical schematic and demonstrate the capabilities made possible by using GENESIS32 SCADA suite. SYSTEM INTEGRATION/ Food Industry 26 Automated process control system for the production of chocolate frosting By Aleksandr Lifanov This article presents a project to modernize a control system for a chocolate frosting production line, describing the unit to be controlled, the production process and the hardware and software. SYSTEM INTEGRATION/ Oil & Gas Industry 32 Automating oil processing: "Customs approves!" By Sergey Baltser, Grigoriy Bushkanets, Vladimir Krasnykh and Artyom Frolov The authors describe building an automation system at an installation for the integrated processing of oil at fields located in the former Soviet republics. 38 Process control system based on the GENESIS32 SCADA suite: a pilot project By Vasiliy Dudnikov, Mariya Yankina, Sergey Savin, Vladimir Maksimenko and Aleksandr Muryzhnikov This article examines the use of the GENESIS32 SCADA suite and demonstrates the broad functionality of this suite. The authors describe the architecture of a process control system for an oil-gathering station. The system collects data and exercises control using an industrial microcontroller.
