31、 worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to ot
32、her activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the
33、 subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditio
34、ns determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC Nationa
35、l Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way i
36、n which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Pu
37、blication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC
38、is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its t
39、echnical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other
40、IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the su
41、bject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. NOTE 1 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 mad
42、e 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 profile parts. Use of the various protocol types in other combinations may require permission of their re
43、spective intellectual-property-right holders. International Standard IEC 61158-3-21:2010 has been prepared by subcommittee 65C: Industrial networks, of IEC technical committee 65: Industrial-process measurement, control and automation. This standard cancels and replaces IEC/PAS 62573 published in 20
44、08. This first edition constitutes a technical revision. 61158-3-21 IEC:2010 5 This bilingual version published in 2012-01 corresponds to the English version published in 2010-08. The text of this standard is based on the following documents: FDIS Report on voting 65C/604/FDIS 65C/618/RVD Full infor
45、mation on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version has not been voted upon. This publication has been drafted in accordance with ISO/IEC Directives, Part 2. A list of all parts of the IEC 61158 series, publishe
46、d under the general title Industrial communication networks Fieldbus specifications, can be found on the IEC web site. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the dat
47、a related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. NOTE 2 The revision of this standard will be synchronized with the other parts of the IEC 61158 series. 6 61158-3-21 IEC:2010 INTRODUCTION This part of IEC
48、61158 is one of a series produced to facilitate 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/TR 61158-1. Throughout the set of fieldbus standards, the term “service” refers t
49、o 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 architectural service, independent of administrative and implementation divisions. 61158-3-21 IEC:2010 7 INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS
