26、roduced 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 protocol provides the application service by making use of the services availab
27、le from the data-link or other immediately lower layer. The primary aim of this standard is to provide a set of rules for communication expressed in terms of the procedures to be carried out by peer application entities (AEs) at the time of communication. These rules for communication are intended t
28、o provide a sound basis for development in order to serve a variety of purposes: as a guide for implementors and designers; for use in the testing and procurement of equipment; as part of an agreement for the admittance of systems into the open systems environment; as a refinement to the understandi
29、ng of time-critical communications within OSI. This standard is concerned, in particular, with the communication and interworking of sensors, effectors and other automation devices. By using this standard together with other standards positioned within the OSI or fieldbus reference models, otherwise
30、 incompatible systems may work together in any combination. BS EN 61158-6-16:2008 5 INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 6-16: Application layer protocol specification Type 16 elements 1 Scope 1.1 General The fieldbus Application Layer (FAL) provides user programs with a me
31、ans 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 in an auto
32、mation 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. Failure to complete specified actions within the ti
33、me window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life. This standard define in an abstract way the externally visible service provided by the different Types of fieldbus Application Layer in terms of an abstract model for
34、defining application resources (objects) capable of being manipulated by users via the use of the FAL service, the primitive actions and events of the service; the parameters associated with each primitive action and event, and the form which they take; and the interrelationship between these action
35、s and events, and their valid sequences. The purpose of this standard is to define the services provided to the FAL user at the boundary between the user and the Application Layer of the Fieldbus Reference Model, and Systems Management at the boundary between the Application Layer and Systems Manage
36、ment of the Fieldbus Reference Model. This standard 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 provided by FAL appl
37、ication-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 application proce
38、ss 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 not include a
39、 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 users in stan
40、dardizing BS EN 61158-6-16:2008 6 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 of this standard is to specify the sy
41、ntax and behavior of the application layer protocol that conveys the application layer services defined in IEC 61158-5-16. 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 o
42、f protocols standardized in subparts of IEC 61158-6. 1.3 Conformance This 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 appli
43、cation layer service definition standard. Instead, conformance is achieved through implementation of conforming application layer protocols that fulfill any given Type of application layer services as defined in this standard. 2 Normative references The following referenced documents are indispensab
