TABLE OF CONTENTS CTA 4/2004 DEVELOPMENT/ Electrical Industry 46 Automated system of extrusion line control By Andrey Robin, Vyacheslav Pimenov The article is dedicated to automated system of extrusion line control, which supports the high isolation quality of cables manufacturing. Such result is achieved by the application of safety industrial computer, SCADA-system based software as well as PID control implementation developed by the authors of the article. DEVELOPMENT/ Research 52 Automated process of industrial isotope separation at a high filled column stream By Vladimir Kraskin, Valeriy Pevtsov, Anatoliy Petrov The article reports on different aspects of automatic process control system for isotope rectification industry based on the example of stand control system for oxygen isotope separation research work. Special attention is given to facilities, which should fit to the modern software and open international standard require- ments. Such facilities application provides and supports the reliability of distributed technological control. SOFTWARE/ Software Tools 60 Let's start working with ReportWorX.NET By Anna Dolgova Some simple operations which allow to start working with ReportWorX.NET immedi- ately and get acquainted with its basic facilities such as template setup, data filling, time schedule setting up and reports redirections are described in details. ENGINEER'S NOTEBOOK 68 Iconics' technical support: new software By Anna Dolgova Q&A 74 Microcontrollers LOGO! By Aleksei Barmin EXHIBITIONS, CONFERENCES, SEMINARS 76 PTA-2004 – PTA-2005: head on to Expocentr By Leontiy Bukshtein 82 The third Moscow Intel Developer Forum: frequency is not important By Aleksandr Lipnitskiy EMPLOYMENT 86 SHOWROOM 87 SYSTEM INTEGRATION PROJECTS IN BRIEF 93 News 26, 67, 84 REVIEW/ Hardware 6 Level measuring by guided EM pulse By Victor Zhdankin Direct electromagnetic radiation method allows to measure liquid indicator, the level for friable hard materials, intermediate stage substance in aggressive environments, extended temperature and pressure variation range in the low dielectric constant of a control product. The article reports on the method's physical properties, as well as its comparison with ultrasonic and non-contact radar methods. The level meters "Pulscon" are described as an example of sensors, which implement the direct electromagnetic method. Practical recommendations on microwave level measuring sensors applications are made. SYSTEM INTEGRATION/ Metallurgy 16 System of direct digital control for Blooming main electric drive By Aleksei Homyak, Aleksei Svetlichniy, Sergey Zajchenko, Pyotr Tarskov, Pavel Rozkaryaka, Roman Fedoryak The article describes development and implementation of direct digital control system for the main electric drive of Blooming rolling mill 1300 at the "Krivorojstal" metallurgical plant. Analysis of technological requirements to operating characteristics of the electric drive is presented, hardware and software approaches that meet the requirements, are described too. 24 Computer-based equipment monitoring system for continuously bar mill By Vladimir Romanovskiy, Aleksei Svetlichniy, Pyotr Tarskov, Anatoliy Shevchenko The article reports on development and embedding of computer-based equipment monitoring system for continuously bar mill 900/700/500 at the "Krivorojstal" metal- lurgical plant. System's functional capabilities and details of its hardware implemen- tation are described. DEVELOPMENT/ Railway Transport 28 Automated control system ACK-3 for industrial facilities By Aleksandr Fendrikov, Sergey Konovalov, Vladimir Rechmedilov, Aleksandr Fendrikov, Dmitriy Zhigalkin, Aleksei Krivoruchko, Pyotr Topolskiy The ACK-3 System is developed for solving the problems of low industrial and trans- port automatic performance. It performs acquisition, handling and information visu- alization and control functions. The description demonstrates large-scale capabilities of the system based on a chosen structure and specific basic software. An ACK-3 based onboard monitoring system developed for export-oriented track machine ADM-1sm is provided as an example. 36 Unified display and registration facilities for electric locomotive diagnostic operations By Dmitriy Ivakhnenko, Igor Badyan, Dmitriy Podust The article reports on unified locomotive microprocessor displaying, registration and diagnostics system for AC and DC locomotives. Basic system hardware and different design styles are described. The article also contains the description of displayed information, recorded data view mode, operator's informational support, emergency sounds and other solutions dedicated to system's ergonomics and control safety increasing. DEVELOPMENT/ Power Engineering 40 Drive modernization at row coal feeding device By Aleksei Petrov, Nikolay Tatarintsev The choice and application of frequency-regulated drives at row feeding devices of steam generating units are described in this article. The economic indicators analysis of DC drives substitution by modern asynchronous regulated drive with variable-frequency control is made. Reliability of the conclusions and recommendations described in the article is proved by successful experience of similar solutions. CD-ROMs in this issue Iconics, Siemens СТА 4/2004 www.cta.ru 96
