35、tomation. O3neida was founded in 2003 as a Community of Common Interest of the International Research andDevelopment Program Intelligent Manufacturing Systems (IMS) and incorporated in 2004 as a Canadiannot-for-profit corporation. O3neidas mission is to operate as a network of networks fostering the

36、 develop-ment and deployment of industrial automation technologies based on open standards including, amongothers, the Foundation for Intelligent Physical Agents (FIPA), the Device Profile for Web Services(DPWS), Web Crawler (WC), International Electrotechnical Commission (IEC) 61131 and IEC 61499.

37、This first book in the series is designed for professionals who teach university courses and for industrypractitioners who seek to understand better the industrial automation field in order to implement specificsolutions in their facilities and enterprises. The focus of this book is the IEC 61499 St

38、andard for FunctionBlocks for Industrial Process Measurement and Control Systems (IPMCS). In producing this book,O3neida hopes to fill the current gap in the marketplace with an informative, effective training manual.Since the production of this first book in the O3neida/ISA series on industrial aut

39、omation, O3neida andISA have collaborated to produce five additional books on subjects ranging from domain ontologies toreal-time execution for IEC 61499 to closed-loop Product Life Cycle Management to the recently pub-lished agent-based volumes which will address other equally pressing issues, such

40、 as Agent-based Tech-nology Manufacturing Control Systems. O3neida will also publish materials on automation objects as partof this series.Finally, this book is the result of a concerted effort among many O3neida members, particularly AllanMartel, Chief Operating Officer of O3neida for his managemen

41、t of the entire publications series. I thankthem all for their dedication and commitment to O3neida as volunteers, and I particularly thank ValeriyVyatkin of the University of Auckland, New Zealand for writing and revising this book. I also thank ISAfor their interest and support in making the publi

42、cation and distribution of this important book possible.Antonio ValentiniChief Executive Officer, O3neidaxiiiAcknowledgmentsThis book was conceived within O3neida, an international network of networks focused on issues relatedto distributed industrial automation.The contributions of James Christense

Dr. James Christensen started the IEC 61499 education mission as the pioneer of object-oriented engi-neering in industrial automation and the leader of the Standards Working Group in IEC. He is the authorof the F

In particular, he wrote the section“Industrial Trends” discussed in Chapter 3.Prof. Jos Lastra generate

The author especially thanks Allan Martel, O3neidas Chief Operating Officer, for his editing andcoordinating assistance. Antonio Valentini, O3neidas CEO, has also provided valuable insights from the perspecti

49、inuous support during the process of completing this book.xvIntroductionThis book is a practical guide to component-based development of distributed, embedded, and control sys-tems proposed within the new IEC 61499 international standard. IEC 61499 defines a component-basedmodelling approach using function blocks. At first glance, this model appears to be quite different from the component models of other softwareengineering approaches such as CORBA, DCOM, or .NET (Snder et al., 2006). In fact, however, a func-tion block possesses the required characteristics of a
