15、llel vote and was approved by CENELEC as EN 61158-4-17 on 2008-02-01. This and the other parts of the EN 61158-4 series supersede EN 61158-4:2004. With respect to EN 61158-4:2004 the following changes were made: deletion of Type 6 fieldbus, and the placeholder for a Type 5 fieldbus data-link layer,
16、for lack of market relevance; addition of new fieldbus types; partition into multiple parts numbered 4-1, 4-2, , 4-19. 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 by endorsement (dop) 2008-11-
17、01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-02-01 NOTE Use of some of the associated protocol types is restricted by their intellectual-property-right holders.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 intellectual-property-rights m
18、ade 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. Use of the various protocol types in other combinations may require permission fro
19、m their respective intellectual-property-right holders. IEC and CENELEC draw attention to the fact that it is claimed that compliance with this standard may involve the use of patents as follows, where the xx notation indicates the holder of the patent right: Type 17 and possibly other types: PCT Ap

25、 COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 4-17: Data-link layer protocol specification Type 17 elements 1 Scope 1.1 General The data-link layer provides basic time-critical messaging communications between devices in an automation environment. This protocol provides communication opportun
26、ities to all participating data-link entities a) in a cyclic asynchronous manner, sequentially to each of those data-link entities, and b) in a synchronous manner, either cyclically or acyclically, according to a pre-established schedule. The specified protocol also provides means of changing the se
27、t of participating data-link entities and of modifying the set of scheduled communications opportunities. When the set of scheduled communications opportunities is null, the distribution of communication opportunities to the participating data-link entities is completely asynchronous. Thus this prot
28、ocol can be characterized as one which provides access asynchronously but with a synchronous overlay. 1.2 Specifications This standard specifies a) procedures for the timely transfer of data and control information from one data-link user entity to a peer user entity, and among the data-link entitie
29、s forming the distributed data- link service provider; b) the structure of the fieldbus DLPDUs used for the transfer of data and control information by the protocol of this standard, and their representation as physical interface data units. 1.3 Procedures The procedures are defined in terms of a) t
30、he interactions between peer DL-entities (DLEs) through the exchange of fieldbus DLPDUs; b) the interactions between a DL-service (DLS) provider and a DLS-user in the same system through the exchange of DLS primitives; c) the interactions between a DLS-provider and a Ph-service provider in the same
31、system through the exchange of Ph-service primitives. 1.4 Applicability These procedures are applicable to instances of communication between systems which support time-critical communications services within the data-link layer of the OSI or fieldbus reference models, and which require the ability
32、to interconnect in an open systems interconnection environment. Profiles provide a simple multi-attribute means of summarizing an implementations capabilities, and thus its applicability to various time-critical communications needs. 6 BS EN 61158-4-17:2008 Copyright British Standards Institution Pr
