    Programmable logic controller is the topic of this paper. For several decades, programmable logic controllers (PLCs) have been the most often used implementation platform for control algorithms in industrial applications. After their introduction in 1969, various companies developed PLCs with different run-time environments, operating systems, and programming languages. To reduce complexity for the users of PLCs, the International Electrotechnical Commission (IEC) elaborated the standard IEC 61131. IEC 61131-3 (published in 1992) specifies five PLC programming languages based on the existing programming languages but abstracting from proprietary peculiarities: the textual programming languages instruction list (QV) and structured text (ST), the graphical programming languages function block diagram (FBD) and ladder diagram (LD), and the structuring tool and higher level programming language sequential function chart (SFC). Although programmers had to get used to these languages first, they have now become a standard that is accepted and appreciated around the world, as it reduces training efforts and fosters harmonization. The integration of motion control and safety functions are discussed in this paper. View full abstract»

  • XML exchange of control programs

    The XML interface defined by PLCopen allows software reuse through interoperability between development tools, as it provides the ability to transfer the information that is on the screen to other platforms. This article presented a way to give any development environment that does not yet support the PLCopen interface the ability to import/export XML files following such a format and, thus, making code really exchangeable. However, the profit to be made may be much more than code reuse, as the interface can be used to interoperate with other software tools, such as configuration, documentation, version control, modeling, and simulation tools.

  • Object-oriented extensions for iec 61131-3

    Industrial programmable logic controllers (PLCs), however, are still mostly programmed in the languages of the International Electrotechnical Commission (IEC) 61131-3 standard. To meet the challenges of modern industrial automation, it is therefore only logical to add OOP to the upcoming third edition of the standard. At the moment, an IEC 61131-3 maintenance group is discussing a working draft of this next edition. This draft contains a proposal for object-oriented extensionsto be added to the IEC 61131-3. This article refers to this proposal. It is, however, a fact that the standardization in regards to OOP is still at an early stage, and it is quite possible that this article may differ from the final edition of the IEC standard.

    The article is structured as follows. In the "System-Level Design for Distributed Automation" section, we give a general introduction to IEC 61499 in terms of its value for the automation systems developer. In the "Elements of IEC 61499 Architecture" section, the basic elements of the IEC 61499 architecture are presented using an illustrative example. The semantic problems of IEC 61499 are outlined in the "Semantic Problems of IEC 61499" section. The "Semantics of a Basic FB" section focuses on the problems and solutions related to the basic function block (FB) behavior. It is followed by the "Semantics of FB Networks" section that discusses semantic problems related to composite FB structures. In the "conclusions" section, we list some open problems.

  • Is IEC 61499 in harmony with IEC 61131-3?

    This year marks the 16th anniversary of the International Electrotechnical Commission (IEC) 1131-3 (now IEC 61131-3), currently one of the most important standards in industrial automation. Four years before its release, it has been decided that it will define a further standard for programming industrial control systems, the IEC 61499 standard. One reason for this decision has been the remarkable, and still current study, of the Iacocca Institute [ 1 ]. This study identified: portability-software tools can accept and correctly interpret software components and system configurations produced by other software tools; interoperability-embedded devices can operate together to perform the functions needed for distributed applications; configurability-any device and its software components can be configured by software tools from multiple vendors; reconfiguration-the ability to adapt control hardware and software during operation; distribution-the ability to distribute software components onto different hardware devices, as requirements demanded from future industrial process measurement and control systems (IPMCS) by the automation industry.

  • Neural network architectures and learning algorithms

    Neural networks are the topic of this paper. Neural networks are very powerful as nonlinear signal processors, but obtained results are often far from satisfactory. The purpose of this article is to evaluate the reasons for these frustrations and show how to make these neural networks successful. The following are the main challenges of neural network applications: (1) Which neural network architectures should be used? (2) How large should a neural network be? (3) Which learning algorithms are most suitable? The multilayer perceptron (MLP) architecture is unfortunately the preferred neural network topology of most researchers. It is the oldest neural network architecture, and it is compatible with all training softwares. However, the MLP topology is less powerful than other topologies such as bridged multilayer perceptron (BMLP), where connections across layers are allowed. The error-back propagation (EBP) algorithm is the most popular learning algorithm, but it is very slow and seldom gives adequate results. The EBP training process requires 100-1,000 times more iterations than the more advanced algorithms such as Levenberg-Marquardt (LM) or neuron by neuron (NBN) algorithms. What is most important is that the EBP algorithm is not only slow but often it is not able to find solutions for close-to-optimum neural networks. The paper describes and compares several learning algorithms. View full abstract»
