14、mitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61158-3-18 on 2008-02-01. This and the other parts of the EN 61158-3 series supersede EN 61158-3:2004. With respect to EN 61158-3:2004 the following changes were made: deletion of Type 6 fieldbus, and the placeholder for a Typ
15、e 5 fieldbus data-link layer, for lack of market relevance; addition of new fieldbus types; partition into multiple parts numbered 3-1, 3-2, , 3-19. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or
16、 by endorsement (dop) 2008-11-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-02-01 NOTE Use of some of the associated protocol types is restricted by their intellectual-property-right holders. In all cases, the commitment to limited release of
17、intellectual-property-rights made by the holders of those rights permits a particular data-link layer protocol type to be used with physical layer and application layer protocols in type combinations as specified explicitly in the EN 61784 series.

It is related to other stan
31、dards 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 abstract capability provided by one layer of the OSI Basic Reference Model to the layer immediately above. Thus, the data-
32、link layer service defined in this standard is a conceptual architectural service, independent of administrative and implementation divisions.

33、OMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 3-18: Data-link layer service definition Type 18 elements 1 Scope 1.1 Overview This standard provides common elements for basic time-critical and non-time-critical messaging communications between devices in an automation environment and material sp
34、ecific to Type 18 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 time window risks failure of the app
35、lications 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 Type 18 fieldbus data-link layer in terms of a) the primitive actions and events of the service; b) the parameter
36、s 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. This standard defines the services provided to the Type 18 fieldbus application layer at the boundary between the application and
37、 data-link layers of the fieldbus reference model, and system management at the boundary between the data-link layer and systems management of the fieldbus reference model. 1.2 Specifications The principal objective of this standard is to specify the characteristics of conceptual data-link layer ser
38、vices 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 objective is to provide migration paths from previously-existing industrial communications protocols. Thi
39、s 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 issues not covered by this specification, including: a) the sizes and octet ordering of various multi-octe
40、t 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 do they constrain the implementations of data-link entities within industrial automation syst
41、ems. 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 fulfills the Type 18 data-link layer services defined in this standard.
