Together with all of the other sections of BS EN 61158-4, it supersedes BS EN 61158-4:2004 which is withdrawn
3、. The UK participation in its preparation was entrusted to Technical Committee AMT/7, Industrial communications Process measurement and control, including Fieldbus. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to

This and the other parts of the EN 61158-4 series
13、 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, for lack of market relevance; addition of new fieldbus types; partition into multiple parts numbered 4-1, 4-2, , 4-19.
14、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or by endorsement (dop) 2008-11-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-02-01 NOTE Use o

In all cases, the commitment to limited release of intellectual-property-rights made by the holders of those rights permits a particular data-link layer protocol type to be used with physical layer an

Use of the various protocol types in other combinations may require permission from their respective intellectual-property-right holders. IEC and CENELEC draw attention to the fact that it is claimed t

This standard is concerned, in particular, with the communication and interworking of sensors, effectors
21、and other automation devices. By using this standard together with other standards positioned within the OSI or fieldbus reference models, otherwise incompatible systems may work together in any combination. 5 BS EN 61158-4-17:2008 INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 4-17:
22、 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 opportunities to all participating data-link entities a) in a cycl
23、ic 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 set of participating data-link entities and of modifying the
24、 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 protocol can be characterized as one which provides access asy
