    The IEC 1131-3 standard describes a set of related textual and graphical programming languages. They are related in the sense that it is possible to define the constructs of one language in terms of another. Furthermore, it is possible to mix and match the languages in a single application, using whatever is most appropriate for the part of the application being dealt with. Now that the standard h...

  • The effect of IEC 1131-3 on the testing process for real time software applications [PLCs]

    Publication Year: 1993, Page(s):4/1 - 4/3

    IEC 1131-3 provides an excellent opportunity for PLC vendors to assist the test engineer. The implementation will facilitate the testing process and will lead to portability of tested software a reduced learning curve, a consistent programming methodology and increased reliability. It is not envisaged that this will happen overnight but the vendors should be encouraged to include the standard in t... View full abstract»

    This paper outlines work in the ESPRIT project `Design Support for Distributed Industrial Controllers' (DSDIC) to support and use the IEC 1131 standard in the production of large scale distributed industrial automation systems. The paper describes the general architecture and technical approach of DSDIC and discusses some of the practical problems that arise when applying the IEC standard View full abstract»

  • PLC control of a cold store and ripening plant-a case history

    Publication Year: 1993, Page(s):8/1 - 8/3
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (168 KB)

    The success of modern refrigeration methods, involving close control of cold store environments, is due in large part to the availability of low cost control systems employing intelligent programmable logic controllers, and PC-based SCADA (supervisory control and data acquisition) systems. TA Consultancy Services were tasked to supply the software-based control system for a multi-chamber cold stor... View full abstract»

  • The need for standardisation of diagnostic techniques [for PLC programs]

    Publication Year: 1993, Page(s):2/1 - 2/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (272 KB)

    This paper welcomes moves towards a standardised programming language for PLCs, but suggests that it is already time to start looking at the way such a language might be applied. A combination of standard programming language, standard methods and object-oriented program generation will ensure that automation loses its image of being a complex subject, too difficult for smaller companies to take o...

  • Software engineering methods for safe programmable logic controllers (SEMSPLC)

    Publication Year: 1993, Page(s):3/1 - 3/3
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (156 KB)

    The SEMSPLC project is a collaborative research programme funded by DTI and SERC. Its primary objective was to establish a software engineering method suitable for development of safety critical PLC based programs in an application language suited to industrial control. The members of the project fall into two distinct communities: those with a conventional software engineering background, and tho... View full abstract»

  • The new IEC 1131 standard for programmable controller languages brings the benefits of `open systems' to industrial control systems

    Publication Year: 1993, Page(s):1/1 - 1/6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (336 KB)

    Reviews the benefits to be gained in developing industrial control systems using products that are based on languages and architecture formalised by the IEC 1131 standard for programmable controllers: (1) The languages encourage a well-structured `top-down' or `bottom-up' program development though use of typed functional elements such as functions, function blocks and programs. (2) The languages ... View full abstract»
