TABLE OF CONTENTS CTA 2/2008 HARDWARE/ Power Supplies 68 New series of the XP Power DC/DC converters By Albert Baishev This article gives an overview of a new series of the XP Power DC/DC converters. Their specific features and main competitive advantages are shown. HARDWARE/ Industrial Controllers 76 Schneider Electric presents the new Modicon M340 PLC By Mikhail Makarov The article provides a brief description of a new Micro programmable logic controller added to the family of the Schneider Electric instrumentation, its features and capabilities. The applications of this PLC in various industries are discussed. HARDWARE/ Drives 78 Lexium PAC: automation technologies and motion control By Aleksandr Ganin The article describes the Lexium PAC servosystems offering the ready combinations of motion control and automation products which enable the design of applications and the implementation of all motion control functions. STANDARDS AND CERTIFICATION 80 Digital measurement metrology. Part 2 By Arkadiy Gurtovtsev The article analyses the basic concepts of the metrology of the measuring systems and its modification – the automatic power consumption accounting and monitoring system. The article shows the drawbacks of the historical methods of the metrological certification of the digital measuring systems and the automatic power consumption accounting and monitoring system. It is suggested that in the said modern systems, only their input part – the primary digital measuring devices or the measuring channels with the digital output – should be metrologically certified as the measuring devices, and the other system devices should be considered as the secondary non measuring devices which require the digital certification, but not the metrological one. Such approach allows the considerable reduction of costs for the metrological support of the measuring systems and the automatic power consumption accounting and monitoring system. ENGINEER'S NOTEBOOK 90 Hardware redundancy in industrial automation. Part 1 By Victor Denisenko Redundancy is practically the only way for providing fail safe operation or functional safety of the automatic systems. The article gives an overview of the well known “hot” and “warm” redundancy methods as well as the voting method performed well in the industrial automation systems. EXHIBITIONS, CONFERENCES, SEMINARS 100 XIII International Forum “Security and Safety Technologies” By Ekaterina Smirnova SHOWROOM 102 SYSTEM INTEGRATION PROJECTS IN BRIEF 109 NEWS 31, 54, 82, 101 REVIEW/ Hardware 6 Structure of the modern embedded modular systems with the network architecture By Vyacheslav Vinogradov The article describes the specific features of the embedded systems having a modular structure. Also discussed are the disadvantages of the trunk systems with the traditional bus architecture and their limited capabilities for further increase in performance. The article covers the solutions reflecting a tendency of gradual transition to a new generation of the modular systems with the advanced switched network architecture and a wide frequency band. 20 On board computers: ready system design options By Aleksei Pyatnitskikh The article presents the ready to use embedded systems made in accordance with the PC/104 standard. The features of the architecture and the general approaches to construction of the modern highly reliable on board computers designed for mobile applications and operation in harsh environments are described. 24 Chassis for the industrial computers with the CompactPCI bus By Vladimir Belomyttsev The article focuses on the design features as well as the basic advantages and disadvantages of various types of chassis for the industrial computers with the CompactPCI system bus. SYSTEM INTEGRATION/ Oil & Gas Industry 28 Automated process control system for the gas gathering station of the underground gas storage facility By Denis Andreyakhin The article describes the automated process control system for the gas gathering station of the underground gas storage facility. The system provides reliable and efficient operation of the gas injection, formation pressure maintenance and gas offtake equipment. 36 Automation of the gas distribution station network based on the Kaskad SAU hardware software complex By Aleksandr Khudov, Roman Mochalov and Andrey Yazev The article describes a system comprising the local process control systems of the gas distribution stations integrated into the SCADA system. Also discussed are the characteristics, hardware design, structure and functions of the system software. DEVELOPMENT/ Oil & Gas Industry 46 An adaptive automatic control system for the electric centrifugal pump preservation bench By Aleksei Komelin The control system of the preservation bench for the electric centrifugal pumps used in oil production does not only allow for carrying out the entire operation cycle in an automatic mode but is also capable of adapting for the capacity of pumps of various types. This system is quite flexible for changing the time parameters of the preservation cycle. The introduction of the control system has let to a substantial increase in the stand performance. 50 Use of the Mitsubishi Electric System Q controllers for the process automation in the oil and gas industry By Sergey Zubov and Andrey Torgashev The article shows the advantages of the control system based on the Mitsubishi Electric controllers as applied to the processes in the oil refining industry.
