The following dates are fixed: latest date by which the document has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2013-09-12 latest date by which the national standards conflicting with the document have to be withdrawn (dow) 2015-1

13、2-12 This document supersedes EN 61499-1:2005. EN 61499-1:2013 includes the following significant technical changes with respect to EN 61499-1:2005: Execution control in basic function blocks (5.2) has been clarified and extended: - dynamic and static parts of the EC transition condition are clearly

14、 delineated by using the ec_transition_eventguard_condition syntax of the Unified Modeling Language (UML) (5.2.1.3, B.2.1); - the terminology “crossing of an EC transition“ (3.10) is used preferentially to “clearing“ to avoid the misinterpretation that the entire transition condition corresponds to

15、a Boolean variable that can be “cleared.“; - operation of the ECC state machine in 5.2.2.2 has been clarified and made more rigorous; - event and data outputs of adapter instances (plugs and sockets) can be used in EC transition conditions, and event inputs of adapter instances can be used as EC act

16、ion outputs. Temporary variables (3.97) can be declared (B.2.1) and used in algorithms of basic function blocks. Service sequences (6.1.3) can now be defined for basic and composite function block types and adapter types, as well as service interface types. The syntax for mapping of FB instances fro

17、m applications to resources has been simplified (Clause B.3). Syntax for definition of segment types (7.2.3) for network segments of system configurations has been added (Clause B.3). Function block types for interoperation with programmable controllers are defined (Clause D.6). The READ/WRITE manag

18、ement commands (Table 8) now apply only to parameters. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC and/or CEN shall not be held responsible for identifying any or all such patent rights. BS EN 61499-1:2013- 3 - EN 6149

43、9-1 IEC:2012 7 INTRODUCTION IEC 61499 consists of the following parts, under the general title Function blocks: Part 1 (this document) contains: general requirements, including scope, normative references, definitions, and reference models; rules for the declaration of function block types, and rule

44、s for the behavior of instances of the types so declared; rules for the use of function blocks in the configuration of distributed industrial-process measurement and control systems (IPMCSs); rules for the use of function blocks in meeting the communication requirements of distributed IPMCSs; rules

45、for the use of function blocks in the management of applications, resources and devices in distributed IPMCSs. Part 2 defines requirements for software tools to support the following systems engineering tasks: the specification of function block types; the functional specification of resource types

46、and device types; the specification, analysis, and validation of distributed IPMCSs; the configuration, implementation, operation, and maintenance of distributed IPMCSs; the exchange of information among software tools. Part 3 (Tutorial information) has been withdrawn due to the widespread current a

47、vailability of tutorial and educational materials regarding IEC 61499. However, an updated 2ndEdition of Part 3 may be developed in the future. Part 4 defines rules for the development of compliance profiles which specify the features of IEC 61499-1 and IEC 61499-2 to be implemented in order to prom

48、ote the following attributes of IEC 61499-based systems, devices and software tools: interoperability of devices from multiple suppliers; portability of software between software tools of multiple suppliers; and configurability of devices from multiple vendors by software tools of multiple suppliers
