26、tate 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. Throughout the set of fieldbus standards, the term “service” refers to the abstract capability provided by one laye
27、r 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.

28、ON NETWORKS FIELDBUS SPECIFICATIONS Part 3-19: Data-link layer service definition Type 19 elements 1 Scope General 1.1This standard provides common elements for basic time-critical messaging communications between devices in an automation environment. The term “time-critical” is used to represent th
29、e 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 risk to equipment, plant an
30、d possibly human life. This standard defines in an abstract way the externally visible service provided by the Type 19 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, and the form which they t
31、ake; 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 19 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model, and s
32、ystems management at the boundary between the data-link layer and systems management of the fieldbus reference model. Specifications 1.2The principal objective of this standard is to specify the characteristics of conceptual data-link layer services suitable for time-critical communications, and thu
33、s 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 standard may be used as the basis for formal DL-Progra
34、mming-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 correlation of paired reques
35、t and confirm, or indication and response, primitives. Conformance 1.3This standard does not specify individual implementations or products, nor do they constrain the implementations of data-link entities within industrial automation systems. There is no conformance of equipment to this data-link la
36、yer service definition standard. Instead, conformance is achieved through implementation of the corresponding data-link protocol that fulfills the Type 19 data-link layer services defined in this standard.
