33、ne 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. Throughout the set of fieldbus standards, the term “service” refers to the abst
34、ract capability provided by one layer of the OSI Basic Reference Model to the layer immediately above. Thus, the data-link layer service defined in this standard is a conceptual architectural service, independent of administrative and implementation divisions. BS EN 61158-3-17:200861158-3-17 IEC:200
35、7(E) 7 INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 3-17: Data-link layer service definition Type 17 elements 1 Scope This part of IEC 61158 provides common elements for basic time-critical messaging communications between devices in an automation environment. The term “time-critic
36、al” 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 requesting the actions, with attendant
37、risk to equipment, plant and possibly human life. This standard defines in an abstract way the externally visible service provided by the Type 17 fieldbus data-link Layer in terms of a) the primitive actions and events of the service; b) the parameters associated with each primitive action and event
38、, and the form which they take; and c) the interrelationship between these actions and events, and their valid sequences. The purpose of this standard is to define the services provided to the Type 17 fieldbus application layer at the boundary between the application and data-link layers of the fiel
39、dbus reference model, and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model; specifications The principal objective of this standard is to specify the characteristics of conceptual data-link layer services suitable for time-critical
40、 communications, and thus supplement the OSI Basic Reference Model in guiding the development of data-link protocols for time-critical communications. A secondary objective is to provide migration paths from previously-existing industrial communications protocols. This specification may be used as t
41、he basis for formal DL-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-octet service parameters, and b) the
42、correlation of paired request and confirm, or indication and response, primitives. Conformance This standard does not specify individual implementations or products, nor does it constrain the implementations of data-link entities within industrial automation systems. There is no conformance of equip
43、ment to this data-link layer service definition standard. Instead, conformance is achieved through implementation of the corresponding data-link protocol that fulfills the Type 17 data-link layer services defined in this standard.
