12、e International Electrotechnical Commission (IEC) is a 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 an
13、d electronic fields. To this end and in addition to other 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 co
14、mmittees; any IEC National Committee interested in the 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
15、 for Standardization (ISO) in accordance with conditions 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 commit
16、tee has representation from all interested IEC National 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
17、accurate, IEC cannot be held responsible for the way in 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 re
18、gional publications. Any divergence between any IEC Publication 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,
19、in some areas, access to IEC marks of conformity. IEC 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 ag
20、ents including individual experts and members of its technical 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
21、, or reliance upon, this IEC Publication or any other 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
22、 of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may prop
23、ose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibili
24、ty of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC 62771, which is a technical specification, has been prepared by IEC technical committee 3: Inf
25、ormation structures, documentation and graphical symbols. 4 TS 62771 IEC:2012(E) The text of this technical specification is based on the following documents: Enquiry draft Report on voting 3/1080/DTS 3/1102/RVC Full information on the voting for the approval of this technical specification can be f
26、ound in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 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:/we
27、bstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The co
28、lour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. TS 62771 IEC:2012(E) 5 INFORMATION MODEL COVERING THE CONTENTS
29、 OF IEC 81346-1 AND IEC 81346-2, IEC 61175, IEC 61666 AND IEC 81714-3 1 Scope This Technical Specification contains a formal reference information model of the concepts and methods established in IEC 81346-1, IEC 81346-2, IEC 61175, IEC 61666 and IEC 81714-3, which are its normative basis. The infor
30、mation model is normative with respect to data exchange. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the lates
31、t edition of the referenced document (including any amendments) applies.

35、of the IEC 61360 series will be modified to: Standard data element types with associated classification scheme for products and services, with Part 1: Definitions, principles and methods, Part 2: EXPRESS Dictionary schema, Part 4: IEC reference collection for products and services used in electrotec
36、hnology, and Part 5: Extensions to the EXPRESS dictionary schema. Likewise the title of the database will be: IEC 61360-DB: IEC Common Data Dictionary. 6 TS 62771 IEC:2012(E) 4 General The standards IEC 81346-1, IEC 81346-2, IEC 61175, IEC 61666 and IEC 81714-3 are interrelated, but the concepts use
37、d in these standards have so far only been dealt with separately in the different publications. The purpose of the present technical specification is to illustrate their relations by means of a common reference information model. When data is transferred or exchanged, the exchange shall conform to t
38、his reference model. The model is conceptual and independent from any implementation method. For the preparation of the information model, the EXPRESS modelling language, described in ISO 10303-11, has been used. The graphical form is presented using EXPRESS-G. The information model is contained in
39、Annex A. 0 provides an overview by means of a graphical representation of the structure and constraints of the application objects. The computer interpretable textual form is represented in A.3. A.1 lists the entities and attributes of the information model and A.2 contains the detailed verbal descr
40、iptions of the entities and attributes. The reference information model depicts the requirements set up, using where possible available subsets of application reference models of the ISO 10303 series. The model is not intended to be complete within the framework of neither integrated resource models
41、 nor application reference models developed within the ISO 10303 series. It is complete with respect to the requirements established within this publication. NOTE 1 For an introduction to EXPRESS-G, see http:/tc3.iec.ch/txt/xpress.pdf. NOTE 2 Annex A is available in the English language only. Annex
42、B contains a set of source definitions for Data Element Types (DETs) derived from the common reference information model.
