It is related to other standards in the set as defined by the “t
32、hree-layer” fieldbus reference model described in IEC/TR 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 appl
33、ications and/or system management may exploit. 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 conce
34、ptual architectural service, independent of administrative and implementation divisions. BS EN 61158-5-16:200861158-5-16 IEC:2007(E) 7 INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 5-16: Application layer service definition Type 16 elements 1 Scope 1.1 Overview The fieldbus applicat
35、ion layer (FAL) provides user programs 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 commun
36、ications between application programs in an automation environment and material specific to Type 16 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. Fai
37、lure to complete specified actions within 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 fieldbus application layer in t
38、erms of a) an abstract model for 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)
39、the interrelationship between these 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
40、between the application layer and Systems Management of the fieldbus reference model. This standard specifies the structure and services of the fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498) and the OSI application layer structure (ISO/IEC 9545). FAL ser
41、vices and protocols are 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 o
42、perate on a set of related 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
43、 issued and delivered, they 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 send/receive is specified. This permits
44、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. BS EN 61158-5-16:2008 8 61158-5-16 IEC:2007(E) 1.2 Specifica
45、tions The principal objective 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 communica
46、tions. 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 standardized as the various Types of IEC 61158, and the corresponding protocols standardized in subparts
47、of 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 interface will need to address implementation issues not covered by this specification, including a) the sizes and octet ord
48、ering of various multi-octet service parameters, and b) the correlation of paired request and confirm, or indication and response, primitives. 1.3 Conformance This standard does not specify individual implementations or products, nor does it constrain the implementations of application layer entitie
49、s within industrial automation systems. There is no conformance of equipment to this application layer service definition standard. Instead, conformance is achieved through implementation of conforming application layer protocols that fulfill the application layer services as defined in this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
