    EPC:It is a common form of contracting arrangement within the construction industry. Under an EPC contract, the contractor will design the installation, procure the necessary materials and construct it, either through own labour or by subcontracting part of the work. The contractor carries the project risk for schedule as well as budget in return for a fixed price, called Lump sum or LSTK depending on the agreed scope of work.

    ESL: As system-on-chip (SoC) designs grow ever more complex, developers are turning to electronic-system-level (ESL) solutions. Designed to improve productivity, reduce risk and tackle growing design complexity, ESL methodologies support mixed-language descriptions and IP reuse, and are targeted at very complex SoC and heterogeneous designs. With ESL, hardware and software can be developed and verified in parallel, problems can be identified and resolved much earlier in the design flow, and tasks that used to consume years of time and effort can now be completed in months. Under the "ESL Now!" banner, more than twenty companies representing a wide variety of ESL modeling, verification, software tools generation and synthesis solutions, services and standards are banding together to spread awareness of ESL.

    The FDT (Field Device Tool) technique has been developed by a workgroup attended by representatives of more than 20 major process automation companies. The target was to find a solution (open interface) for instrument configuration and mangement by a central system engineering tool, no matter which communication protocol used. The result is a vendor and protocol independent FDT specification defining interfaces on the basis of internet technologies (ActiveX/COM, XML, ...). With this, instruments can be seamlessly integrated into engineering or stand-alone tools by using a software component, which is called DTM (Device Type Manager).
    The DTM is provided by the device vendor, holds the entire information of the instrument and provides means to fully configure, maintain and manage the instrument via a comfortable, standardised graphical interface.
    FIRST: Accomplished inventor Dean Kamen founded FIRST (For Inspiration and Recognition of Science and Technology) in 1989 to inspire an appreciation of science and technology in young people. Based in Manchester, NH, FIRST designs accessible, innovative programs to build self-confidence, knowledge and life skills while motivating young people to pursue opportunities in science, technology and engineering. With the support of many of the world's most well-known companies, the non-profit organization hosts the FIRST Robotics Competition for high school students and the FIRST LEGO League for children 9 to 14 years old.
    FISCO compliance enables more power to be made available in each fieldbus segment, allowing the connection of further devices in the hazardous area. The advantage to the plant engineer is a simplified installation and less documentation needed to show the safety of the installation.

    SOPRO is a project which aims at revolutionizing the manufacturing industry. Research is carried out by a consortium of several Fraunhofer-Institutes and the Technical University of Berlin led by the Fraunhofer-Institute for Production Systems and Design Technology (IPK). The German Engineering Federation's (VDMA) associations Micro Technology and Productronics as well as the working group Modular Microsystems coordinate the co-operation with the industry. SOPRO is a government funded project within the framework program "Microsystems Technology" of the Federal Ministry of Education and Research (BMBF). The project management organization is the VDI/VDE Innovation + Technik GmbH, Berlin. The project develops the potential of self-organizing structures in industrial production employing process e-grains. Products and resources are equipped with intelligent process e-grains, which deal autonomously with other partners of the production network. Independent from a control unit they implement production processes according to the principle of self-organization.

U

    The OPC UA standard upgrades OPC communications from Microsoft COM/DCOM technology and features enhanced reliability, security and robustness while maintaining a common data model. It will offer best-of-breed integration and also provide the framework for platform neutrality, enabling real-time and historical information interoperability between systems. Moreover, the OPC UA will offer integration with Microsoft Web Services and plant management technologies.
