TABLE OF CONTENTS CTA 1/2007 DEVELOPMENT/ Agriculture 54 Automated control system for underwater fishpond By Andrey Bykadorov and Dmitriy Eremin Incubation in sea ponds is a promising line in fish breeding worldwide. To automate this process, Antrel Company by order of OOO Ekofish has developed and introduced a programmable controller for an autonomous underwater fishpond (PK PARS). HARDWARE/ Conrtollers 58 Fastwel I/O inside By Aleksandr Lokotkov The structure and operation of the basic components of a Fastwel I/O hard- ware-software complex intended for designing automated data acquisition and control systems are considered, and design approaches are discussed. FBUS module-communicating internal bus, an adapted environment for CoDeSys application programs, network protocol services, and interaction between the complex’s basic components are described in detail. SOFTWARE/ Software Tools 66 New approaches of operation with OPC data By Dmitriy Shvetsov Basic advantages of operation of SCADA systems with OPC data are out- lined, and features and disadvantages of the existing data communication protocols are considered. The potential of this approach and available solutions are demonstrated using a new version of Iconics GENESIS32 V9 HMI/SCADA. SOFTWARE/ Real-Time Operating Systems 70 Cheapening of industrial control system design by using adaptive decomposition of system resources By Roman Kiprushenkov As the complexity and volume of codes increase, so does the probability of processor time shortage at the final stage of system development: the process of debugging and integration of the system becomes more sophisticated, and detection and removal of faults become more time- consuming and expensive. The risk that the processor resources will be spent on executing failure-inducing programs is eliminated by using a patented adaptive decomposition technology that assures real-time processor resource allocation between applications. Debugging expenses due to processor resource shortage are cut, and the final product becomes more reliable and protected and comes into the market faster. ENGINEER’S NOTEBOOK 78 PID controllers: design philosophy and modifications. Part 2 By Victor Denisenko The article considers the philosophy of designing PID controllers, which have found wide application in process automation. Attention is also given to controllers for transport-delay systems, as well as to fuzzy and neu- ronet PID controllers. 90 Technique for testing the operation of Fastwel proces- sor boards under QNX operating system By Alexey Uvarov A technique for testing the compatibility of various versions of QNX oper- ating system with application-specific Fastwel processor boards is described. The algorithms and scripts of test programs are presented. An example of stepwise assembling the image of QNX Momentics operating system and an embedded file system along with Photon graphic shell is given. EXHIBITIONS, CONFERENCES, SEMINARS 100 The main event in industrial automation of Ural By Mariya Soldatova 101 CANTech 2007 SHOWROOM 103 SYSTEM INTEGRATION PROJECTS IN BRIEF 109 NEWS 22, 36, 101 SYSTEM INTEGRATION/ Railway Transport 6 Complex automated system of supervisory control for the first line of Kazan underground: up-to-date solutions to standard problems By Vladimir Krasnykh, Grigoriy Bushkanets, Aleksandr Derkach, Boris Krasnykh, Andrey Naumov and Aidar Abdulkin The article describes an automated system providing the functioning of Kazan metro objects – a complex automated system of supervisory con- trol of electromechanical facilities and energy supply objects. SYSTEM INTEGRATION/ Metallurgy 12 Process control system for the foundry equipment of Revda non-ferrous metals processing works By Evgeniy Dubrovskiy, Mikhail Piskunov and Igor Teterin The system described here makes possible monitoring of process param- eters, on-line display of sample analysis results, generation of databases, and equipment failure prevention; thereby, it serves to improve the prod- uct quality. The features of the technological process, as well as hard- ware/software solutions used in designing the system, are described. 18 Control of ingot cutting on a blooming By Igor Ierusalimov, Yurii Karfidov and Aleksei Litvinov A system of ingot cutting control on a blooming is described. It uses image correlation velocimeters to trace the ingot position before cutting. The possibility of integrating the system into a network consisting also of accounting and process monitoring systems is discussed. DEVELOPMENT/ Metallurgy 24 Laser Doppler meters in a hot-rolled metal accounting system By Aleksandr Anikin and Aleksei Fedoseiskiy General information about laser Doppler meters of the rolled-metal veloci- ty and length is given. Updating of LI803M meters and the operation of the hot-rolled metal accounting system using these meters at the Nizhnii Tagil metallurgical works (OAO NTMK) are described. 30 Process control system for the copper concentrating mill at Almalyk mining-and-smelting works By Aleksei Nikitin, Dmitriy Skripchak, Mikhail Semenov, Innokentiy Khan and German Zamanov Problems and experience in designing a selective flotation control system are described. The system is equipped with advanced sensors of process parameter and a reliable programmable controller. Algorithms for calcu- lating the density, solid consumption, and other parameters of the pulp flow using signals from the sensors are presented. DEVELOPMENT/ Railway Transport 38 Application of ADAM-5000/TCP modular microcontrollers for diagnostics of Trakt complex equipment By Sergey Vasiliev The article describes application of ADAM-5000/TCP microcontroller in assembly-line production for diagnostics of the equipment of Trakt com- plex, which is used in centralized traffic control systems in railway trans- port. The choice of ADAM-5000/TCP is based on the fact that it meets design requirements. The hardware and software of the diagnostic com- plex are described. DEVELOPMENT/ Automotive Industry 42 Control system for a bench testing the brake system of GAZ-3310 Valdai car for tightness By Igor Mikhalchenko, Vadim Nizhegorodtsev and Mikhail Polivtsev Application of advanced industrial controllers in control electronics for meas- uring and adjusting benches used to test motor transport is described. DEVELOPMENT/ Research 46 Hardware-software complex for studying algorithms of multiaxis electric drive trajectory interpolation By Victor Bukreev, Nikolay Gusev and Mikhail Kovalenko A single-computer implementation of a numerical control system is con- sidered. The approach is based on software adapted to Windows XP that was developed in Delphi 7 environment using servodrive control algo- rithms developed by the authors.
