TABLE OF CONTENTS CTA 2/2007 The heater-controlling systems allow designers to unify circuit, hardware, and software solutions and also simplify the equipment adjustment during operation and updating. 58 Automated system for controlling a flow gauge calibra- tion bench By Aleksei Komelin and Sergey Ilyasov An automated system for controlling a flow gauge calibration bench is described. Hardware and software tools constituting a basis for this process control system are presented, and the operation of the bench is outlined. DEVELOPMENT/ Power Engineering 64 Projects of mechanical-draft cooling tower automation By Nikolay Kiyanov, Oleg Kryukov, Sergey Lopatnikov, Andrey Smirnov and Dmitriy Pribytkov Modern water-rotation equipment-cooling systems based on mechanical- draft cooling towers are considered. Factors crucial for the service life, reliability, and efficiency of the cooling towers are analyzed. Appropriate circuit-design and algorithmic approaches to automation are suggested. The results of modeling and operation of automated ventilator cooling towers are presented. DEVELOPMENT/ Control & Measuring Systems 72 Automated system for determining mechanical proper- ties of materials By Victor Rozhentsev, Anatoliy Novikov, Aleksandr Shamanin and Andrey Fishchilenko The system described in this article is intended for controlling the loading parameters of general-purpose testing machines determining the strength characteristics of materials. The system is built on an industrial computer. HARDWARE/ Industrial Conrtollers 80 Fastwel I/O inside. Part 2 By Aleksandr Lokotkov The structure and operation of the basic components of a Fastwel I/O hardware-software complex intended for designing automated data acqui- sition and control systems are considered, and design approaches are discussed. FBUS module-communicating internal bus, an adapted envi- ronment for CoDeSys application programs, network protocol services, and interaction between the complex’s basic components are described in detail. ENGINEER’S NOTEBOOK 94 Portable device driver for embedded systems By Maxim Ovod It is hard to imagine a more pleasant moment for a programmer than when he sees that a program on which he has worked hard for several days, months, or even years operates exactly as it must: rapidly and cor- rectly. The article touches upon special programs – drivers. The reader will get to know program design and debugging tools aimed at making a driver flexible and portable as applied to the Windows, Linux, and QNX operational systems. EXHIBITIONS, CONFERENCES, SEMI- NARS 100 PTA – St. Petersburg 2007: new approaches to automa- tion 100 “Modern Energy-Saving Technologies and All-Round Automation from Siemens” conference SHOWROOM 103 SYSTEM INTEGRATION PROJECTS IN BRIEF 109 NEWS 47, 63 REVIEW/ Hardware 8 New-generation Schroff Cabinets By Vladimir Byelomyttsev The trends in designing cabinets produced by Schroff, a leading cabinet manufacture, are considered. SYSTEM INTEGRATION/ Railway Transport 14 Unified software/hardware for electric energy consump- tion automatic accounting at a railway junction and network project implementation By Yelena Emelyanenkova, Sergey Konovalov, Aleksei Uvarov, Vladimir Miretskii, Aleksei Balushkin and Maxim Tsybakov The design of automated systems intended for electric energy consumption commercial accounting at railway junctions, power-hungry objects distributed over a vast area, is considered. Criteria for selecting unified software/ hardware are presented, and the networking principles are described. SYSTEM INTEGRATION/ Chemical Industry 20 Control system for a coking plant complex By Victor Veremenko, Vladimir Zamoshnik, Anna Derksen, Maxim Bakharev, Aleksandr Abramov, Aleksei Veremenko and Aleksandr Dyomin A process control system for a coking plant complex is described. The system covers a number of independent networked production areas involved in a production cycle. Some of the basic objectives of the system are accomplished by GENESIS32 SCADA tools. SYSTEM INTEGRATION/ Food Industry 26 Complex approach to designing a process control sys- tem used in alcohol mash production By Aleksandr Gunko, Igor Komissarov and Aleksandr Dorofeev The need for a complex approach to updating production objects is demonstrated. The approach described in this paper was applied at the Kozlov distillery to incorporate the control system used in alcohol mash production into the general alcohol-production-controlling system. The alcohol production technology; the software/hardware, structure, and functions of the control system; and the potentiality of the operator inter- face are described. The final part of the article shows the efficiency of the approaches implemented in practice. SYSTEM INTEGRATION/ Building Automation 32 Building management systems: comfort and economic benefits By Yaroslav Evdokimov and Aleksandr Yakovlev Burning issues concerning building automation, such as hardware platform selection, networking, and optimization of ventilation- and heating-controlling algorithms are touched upon. Experience on introducing automated ventilator units into the Olimp automobile center (St. Petersburg) is described. DEVELOPMENT/ Building Automation 44 How buildings become smart By Dmitriy Shvetsov Modern buildings have many rooms and areas requiring different illumina- tion, safety, and climatic conditions, as well as different levels of informa- tion service. This article describes a smart control system that has become a constituent element of high-class buildings. DEVELOPMENT/ Oil & Gas Industry 48 On-spot loading rack rated at 3 million tons of petrole- um products a year By Andrey Efimov and Dmitriy Levin The article describes an automated clock filling plant that has been put into operation in the oil refinery at OAO Salavatnefteorgsintez. The plant is designed for direct weighing of petroleum products and filling of tank cars through two telescopic filling pipes, as well as for removal of vapors from the filling area or their recuperation. 54 Automated systems controlling gas, oil, and water heating By Aleksandr Efentiev, Roman Efimov and Oleg Malkin The systems described in this article are intended to control various gas jets, keep a product being heated at a desired temperature, meet safety requirements, and detect malfunction. Remote control is also provided. СТА 2/2007 www.cta.ru 112 CD-ROMs in this issue Iconics, Turck
