Automation systems, often referred to as SCADA systems, involve programming at several levels; these systems include computer type field controllers that monitor and control plant equipment such as conveyor systems, pumps, and user workstations that allow the user to monitor and control the equipment through color graphic displays. All of the components of these systems are integrated through a network, such as Ethernet for fast communications.
This book provides a practical guide to developing the application software for all aspects of the automation system, from the field controllers to the user interface workstations. The focus of the book is to not only provide practical methods for designing and developing the software, but also to develop a complete set of software documentation. Providing tested examples and proceducres, this book will be indespensible to all engineers managing automation systems.
The software, communications and electronics markets are among the most innovative and competitive industries in the world. Robust competition means that developers and manufacturers of software, mobile phones, gaming devices, computers, digital cameras and other consumer electronics and appliances must leverage their IP rights to sustain competitive advantage. However, this can be difficult, as much innovation takes place at the intersection of patent, design and copyright law; and although much law is harmonised, there are still significant national variations both in law and in practice. Intellectual Property in Electronics and Software is a new title designed to provide practical guidance on the IP issues affecting companies working in this area. A unique compendium, it addresses the key issues of IP law in the major jurisdictions worldwide where software and electronics are developed and sold as they impact on software and electronics companies. Topics covered include the challenges of obtaining protection; software protection and the limits of patentability; patent strategy, including approaches to patent drafting to maximise protection; standards setting and reasonable and non-discriminatory licensing; open source software; and other forms of protection such as unfair competition and design rights. Written by a team of leading specialists in IP law, the book will serve as an invaluable guide to navigating the complex and overlapping rights which protect innovation in this field.
Software components and component-based software development (CBSD) are acknowledged as the best approach for constructing quality software at reasonable cost. Composing Software Components: A Software-testing Perspective describes a 10-year investigation into the underlying principles of CBSD. By restricting attentionto the simplest cases, startling results are obtained:
. Components are tested using only executable code. Their behavior is recorded and presented graphically.
. Functional and non-functional behavior of systems synthesized from components are calculated from component tests alone. No access to components themselves is required.
. Fast, accurate tools support every aspect of CBSD from design through debugging.
Case studies of CBSD also illuminate software testing in general, particularly an expanded role for unit testing and the treatment of non-functional software properties.
This unique book:
. Contains more than a dozen case studies of fully worked-out component synthesis, with revealing insights into fundamental testing issues.
. Presents an original, fundamental theory of component composition that includes persistent state and concurrency, based on functional software testing rather than proof-of-programs.
. Comes with free supporting software with tutorial examples and data for replication of examples. The Perl software has been tested on Linux, Macintosh, and Windows platforms. Full documentation is provided.
. Includes anecdotes and insights from the author's 50-year career in computing as systems programmer, manager, researcher, and teacher.
Composing Software Components: A Software-testing Perspective will help software researchers and practitioners to understand the underlying principles of component testing. Advanced students in computer science, engineering, and mathematics can also benefit from the book as a supplemental text and reference.
The primary objective of the book is to provide advanced undergraduate or frrst-year graduate engineering students with a self-contained presentation of the principles fundamental to the analysis, design and implementation of computer controlled systems. The material is also suitable for self-study by practicing engineers and is intended to follow a first course in either linear systems analysis or control systerns. A secondary objective of the book is to provide engineering and/or computer science audiences with the material for a junior/senior-level course in modern systems analysis. Chapters 2, 3, 4, and 5 have been designed with this purposein rnind. The emphasis in such a course is to develop the rnathernatical tools and methods suitable for the analysis and design of real-time systems such as digital filters. Thus, engineers and/or computer scientists who know how to program computers can understand the mathematics relevant to the issue of what it is they are programrning. This is especially important for those who may work in engineering and scientific environments where, for instance, programrning difference equations for real-time applications is becorning increasingly common. A background in linear algebra should be an adequate prerequisite for the systems analysis course. Chapter 1 of the book presents a brief introduction to computer controlled systems. It describes the general issues and terminology relevant to the analysis, design, and implementation of such systems.
