27、 FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization i
28、n the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. Intern
29、ational, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The
30、formal decisions or agreements of the 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 National Committees. 3) The documents produced have the form of recommen
31、dations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC Internation
32、al Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval
33、and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance with this International Standard may involve the use of a maintenance servic
34、e concerning the stack of protocols on which the present standard IEC 62056-42 is based. The IEC takes no position concerning the evidence, validity and scope of this maintenance service. The provider of the maintenance service has assured the IEC that he is willing to provide services under reasona
35、ble and non-discriminatory terms and conditions for applicants throughout the world. In this respect, the statement of the provider of the maintenance service is registered with the IEC. Information (see also 6.3.3) may be obtained from: DLMS 1User Association Geneva / Switzerland www.dlms.ch Intern
36、ational Standard IEC 62056-42 has been prepared by IEC technical committee 13: Equipment for electrical energy measurement and load control. This bilingual version (2013-05) corresponds to the monolingual English version, published in 2002-02. _ 1Device Language Message Specification. 4 62056-42 IEC
37、:2002 The text of this standard is based on the following documents: FDIS Report on voting 13/1266/FDIS 13/1272/RVD Full information 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 of this standard has not been vot
38、ed upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. Annexes A and B are for information only. The committee has decided that the contents of this publication will remain unchanged until 2006. At this date, the publication will be reconfirmed; withdrawn; repl
39、aced by a revised edition, or amended.

40、2 IEC:2002 5 ELECTRICITY METERING DATA EXCHANGE FOR METER READING, TARIFF AND LOAD CONTROL Part 42: Physical layer services and procedures for connection-oriented asynchronous data exchange 1 Scope This part of IEC 62056 specifies the physical layer services and protocols within the Companion Specif
41、ication for Energy Metering (COSEM) three-layer connection oriented profile for asynchronous data communication. The document does not specify physical layer signals and mechanical aspects. Local, implementation-specific issues are also not specified. In annex A, an example of how this physical laye
42、r can be used for data exchange through the Public Switched Telephone Network (PSTN) using intelligent Hayes modems is given. The use of the physical layer for the purposes of direct local data exchange using an optical port or a current loop physical interface is specified in IEC 62056-21. Annex B
43、gives an explanation of the role of data models and protocols in electricity meter data exchange. 2 Normative references The following referenced documents are indispensable for the application of this document.
