34、-11 IEC:2007(E) INTRODUCTION This part of IEC 61158 is one of a series produced to facilitate the interconnection of automation system components. It is related to other standards in the set as defined by the “three-layer” fieldbus reference model described in IEC/TR 61158-1. The application service
35、 is provided by the application protocol making use of the services available from the data-link or other immediately lower layer. This standard defines the application service characteristics that fieldbus applications and/or system management may exploit. Throughout the set of fieldbus standards,
36、the term “service” refers to the abstract capability provided by one layer of the OSI Basic Reference Model to the layer immediately above. Thus, the application layer service defined in this standard is a conceptual architectural service, independent of administrative and implementation divisions.
37、BS EN 61158-5-11:200861158-5-11 IEC:2007(E) 7 INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 5-11: Application layer service definition Type 11 elements 1 Scope 1.1 Overview The fieldbus Application Layer (FAL) provides user programs with a means to access the Fieldbus communication
38、environment. In this respect, the FAL can be viewed as a “window between corresponding application programs.” This part of IEC 61158 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material
39、specific to Type 11 fieldbus. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the a
40、pplications requesting the actions, with attendant risk to equipment, plant and possibly human life. This part of IEC 61158 defines in an abstract way the externally visible service provided by the different Types of fieldbus Application Layer in terms of a) an abstract model for defining applicatio
41、n resources (objects) capable of being manipulated by users via the use of the FAL service, b) the primitive actions and events of the service; c) the parameters associated with each primitive action and event, and the form which they take; and d) the interrelationship between these actions and even
42、ts, and their valid sequences. The purpose of this part of IEC 61158 is to define the services provided to 1) the FAL user at the boundary between the user and the Application Layer of the Fieldbus Reference Model, and 2) Systems Management at the boundary between the Application Layer and Systems M
43、anagement of the Fieldbus Reference Model. This part of IEC 61158 specifies the structure and services of the IEC fieldbus Application Layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498) and the OSI Application Layer Structure (ISO/IEC 9545). FAL services and protocols are provid
44、ed by FAL application-entities (AE) contained within the application processes. The FAL AE is composed of a set of object-oriented Application Service Elements (ASEs) and a Layer Management Entity (LME) that manages the AE. The ASEs provide communication services that operate on a set of related app
45、lication process object (APO) classes. One of the FAL ASEs is a management ASE that provides a common set of services for the management of the instances of FAL classes. Although these services specify, from the perspective of applications, how request and responses are issued and delivered, they do
46、 not include a specification of what the requesting and responding applications are to do with them. That is, the behavioral aspects of the applications are not specified; only a definition of what requests and responses they can send/receive is specified. This permits greater flexibility to the FAL
47、 users in standardizing BS EN 61158-5-11:2008 8 61158-5-11 IEC:2007(E) such object behavior. In addition to these services, some supporting services are also defined in this standard to provide access to the FAL to control certain aspects of its operation. 1.2 Specifications The principal objective
48、of this part of IEC 61158 is to specify the characteristics of conceptual application layer services suitable for time-critical communications, and thus supplement the OSI Basic Reference Model in guiding the development of application layer protocols for time-critical communications. A secondary ob
49、jective is to provide migration paths from previously-existing industrial communications protocols. It is this latter objective which gives rise to the diversity of services standardized as the various Types of IEC 61158, and the corresponding protocols standardized in IEC 61158-6. This specification may be used as the basis for formal Application Programming-Interfaces. Nevertheless, it is not a formal programming interface, and any such int
