It is related to other standards in the set as defined by the “three-layer” fieldbu
28、s reference model described in IEC 61158-1. 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 data-link layer service defined in this standard is a conceptual
29、 architectural service, independent of administrative and implementation divisions. BS EN 61158-3-4:2014IEC 61158-3-4:2014 IEC 2014 7 INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 3-4: Data-link layer service definition Type 4 elements 1 Scope General 1.1This part of IEC 61158 provi
30、des common elements for basic time-critical messaging communications between devices in an automation environment. 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
31、. Failure 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 services provided by the Type 4 fieldbus data-link
32、 layer in terms of a) the primitive actions and events of the services; b) the parameters associated with each primitive action and event, 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
33、 the services provided to the Type 4 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model; systems management at the boundary between the data-link layer and systems management of the fieldbus reference model. Specifications 1.2The p
34、rincipal objective of this standard is to specify the characteristics of conceptual data-link layer services suitable for time-critical communications, and thus supplement the OSI Basic Reference Model in guiding the development of data-link protocols for time-critical communications. A secondary ob
35、jective is to provide migration paths from previously-existing industrial communications protocols. This specification may be used as the basis for formal DL-Programming-Interfaces. Nevertheless, it is not a formal programming interface, and any such interface will need to address implementation iss
36、ues not covered by this specification, including a) the sizes and octet ordering of various multi-octet service parameters; b) the correlation of paired request and confirm, or indication and response, primitives. Conformance 1.3This standard does not specify individual implementations or products,
37、nor does it constrain the implementations of data-link entities within industrial automation systems. There is no conformance of equipment to this data-link layer service definition standard. Instead, conformance is achieved through implementation of the corresponding data-link protocol that fulfill
38、s the Type 1 data-link layer services defined in this standard.
