It is related to other standards in the set as defined by the “three-layer” fieldbus reference model

33、 described in IEC 61158-1. The application service 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 e

34、xploit. Throughout the set of fieldbus standards, 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, independen

35、t of administrative and implementation divisions. BS EN 61158-5-4:2014IEC 61158-5-4:2014 IEC 2014 7 INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 5-4: Application layer service definition Type 4 elements 1 Scope General 1.1The fieldbus application layer (FAL) provides user programs

36、with a means to access the fieldbus communication environment. 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 i

37、n an automation environment and material specific to Type 4 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 withi

38、n the time window risks failure of the applications 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 Type 4 fieldbus application layer in terms of a) an abstract model for

39、defining application 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 the

40、se actions and events, and their valid sequences. The purpose of this standard 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

41、 Systems Management of the fieldbus reference model. This standard specifies the structure and services of the Type 4 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

42、provided 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 relat

43、ed application 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, t

44、hey do 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 BS EN 61158-5-4:2014 8 IEC 61158-5-4:2014 IEC 2014 send/receive

45、is specified. This permits greater flexibility to the FAL users 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 o

46、bjective of this standard 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

47、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 series. This speci

48、fication may be used as the basis for formal application programming interfaces. Nevertheless, it is not a formal programming interface, and any such interface will need to address implementation issues not covered by this specification, including a) the sizes and octet ordering of various multi-oct

49、et service parameters, and b) the correlation of paired request and confirm, or indication and response, primitives. Conformance 1.3This standard does not specify individual implementations or products, nor does it constrain the implementations of application layer entities within industrial automation systems. There is no conformance of equipment to this application layer service definition standard. Instead, conformance is achieved through implementation
