CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions. CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. BS EN 61158-4-1:2008 EN 61158-4-1:2008 - 2 - Foreword The text of document 65C/474/FDIS, future edition 1 of IEC 61158-4-1, prepared by SC 65C, Industrial networks, of IEC TC 65, Industrial-process measurement, control and automation, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61158-4-1 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, 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or by endorsement (dop) 2008-11-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-02-01 NOTE Use of some of the associated protocol types is restricted by their intellectual-property-right holders.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 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. 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 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 1 time synchronization and possibly other types: JP Hei4-35096 YC Communication control method IEC and CENELEC take no position concerning the evidence, validity and scope of these patent rights. The holders of these patent rights have assured IEC that they are willing to negotiate licences under reasonable and non- discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holders of these patent rights are registered with IEC. Information may be obtained from: YC: Jun-ichi Tsuboi, Mr. Yamatake Corporation Shibuyaku Shibuya, 2-12-19 Tohtate International Building 150-8316 Tokyo Japan Attention is drawn to the possibility that some of the elements of this standard may be the subject of patent rights other than those identified above. IEC and CENELEC shall not be held responsible for identifying any or all such patent rights. Annex ZA has been added by CENELEC. _ BS EN 61158-4-1:2008 - 3 - EN 61158-4-1:2008 Endorsement notice The text of the International Standard IEC 61158-4-1:2007 was approved by CENELEC as a European Standard without any modification.
