SYSTEM INTEGRATION/ Building Automation 60

Use of light emitting diodes in lighting solutions: history, current reality and future

By Gennadiy Gladyshev, Yurii Efimov and Anton Pribylov

By Andrey Turkin

The article presents hardware and software solutions created when developing and commercializing the supervisory control system for the utilities systems of a complex of buildings of the Executive Office of the System Operator of the Unified Energy System of Russia. It describes a system approach to solving an extensive task – from the development of the user interface differentiated by groups of personnel as well as an appropriate security policy and evaluation of data reliability up to the use of inhouse ActiveX elements. The project is a current typical solution for the tasks of dispatching control of life support systems for critical facilities such as the energy complex control stations, centers for processing banklevel data or data of federal significance and other similar facilities.

The article is devoted to the use of light emitting diodes (LEDs) as light sources for lighting applications. The article describes historical aspects of the development of LED technology and gives an overview of stateoftheart products from key producers. Also discussed are results of the introduction of LED lighting in various facilities. The article provides an assessment of the efficiency of such implementations and the potential to use the LED solutions in lighting systems.

REVIEW/Embedded Systems 22

Choosing an embedded OS for your project By Nikolay Gorbunov The article gives an overview of typical embedded software project requirements and constraints, and provides a mapping between them and major characteristics of embedded OSes. A unified set of embedded OS comparison criteria is suggested, with a few examples of OS selection for a particular case, giving VxWorks, QNX, Wind River Linux, Windows Embedded and RTOS32 as possible OS choices.

SYSTEM INTEGRATION/Food Industry 80

When revamping the existing enterprises, the key requirements are minimization of idle time during the commissioning period and reduction of capital expenditures. The article presents the hardwaresoftware solutions whose implementation allowed for fulfilling these requirements when upgrading the process control system of the finished product shop at a breadbaking complex.

Simplify your life with fieldbus in Zone 2 By Andreas Hennecke In Zone 2 hazardous areas, energy limiting ignition protection type Ex nL (nonincentive) has been available to fieldbus users for years paving the way for instrumentation in an increasing number of installations. Compared to protection type Ex i (intrinsic safety), Ex nL has contradictory requirements that have led to ambiguity regarding correct dimension and construction of electrical circuits rather than the expected savings in installation and maintenance cost. The new directive "Ex ic intrinsic safety" is replacing Ex nL as of 2011. This article explores the improvements that can be realized by combining this new standard with FOUNDATION fieldbus H1 and PROFIBUS PA.

DEVELOPMENT/Food Industry 84

The article describes an experience in using the Siemens stateoftheart developments (APF TP libraries) for the food industry within process control system project for a dairy factory performed by NPO Elevar CJSC. Also discussed are the main stages of the development, use of the virtual plant model based on PHMIE and the basic hardware/software utilized in the process control system.
