35、014 IEC 2014 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 61158-1. The application service is pr
36、ovided 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, the te
37、rm “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. BS EN
38、61158-5-22:2014IEC 61158-5-22:2014 IEC 2014 7 INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 5-22: Application layer service definition Type 22 elements 1 Scope General 1.1The fieldbus application layer (FAL) provides user programs with a means to access the fieldbus communication en
39、vironment. In this respect, the FAL can be viewed as a “window between corresponding application programs.” This standard provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to
40、 Type 22 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 applications
41、 requesting the actions, with attendant risk to equipment, plant and possibly human life. This standard defines in an abstract way the externally visible service provided by the fieldbus application layer in terms of a) an abstract model for defining application resources (objects) capable of being
42、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 events, and their valid sequences. The purp
43、ose of this standard is to define the services provided to a) the FAL user at the boundary between the user and the application layer of the fieldbus reference model; and b) Systems Management at the boundary between the application layer and Systems Management of the fieldbus reference model. This
44、standard specifies the structure and services of the fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545). FAL services and protocols are provided by FAL application-entities (AE) contained within the ap
45、plication 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 application process object (APO) classes. One of the FAL ASEs
46、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 not include a specification of what the requesting and res
47、ponding 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 BS EN 61158-5-22:2014 8 IEC 61158-5-22:2014 IEC 2014 send/receive is specified. This permits greater flexibility to the FAL users
48、 in standardizing 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. Specifications 1.2The principal objective of this standard is to specify the characteristics of
49、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 objective is to provide migration paths from previously-existing industrial communications protocols. It is this latter objective which gives rise to the diversity of services
