19、 11 62026-1 IEC:2007 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR CONTROLLER-DEVICE INTERFACES (CDIs) Part 1: General rules FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
20、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 other activities, IEC publishes International Standards, Technical Spe
21、cifications, 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 subject dealt with may participate in this preparatory work. Intern
22、ational, 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 conditions determined by agreement between the two organizations. 2) The form
23、al 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 National Committees. 3) IEC Publications have the form of recommendations fo
24、r 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 in which they are used or for any misinterpretation by any end user. 4
25、) 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 Publication and the corresponding national or regional publication shal
26、l be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liabi
27、lity shall attach to IEC or its directors, employees, servants or agents 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 (inclu
28、ding legal fees) and expenses arising out of the publication, use of, 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
29、this publication. 9) Attention is drawn to the possibility that some 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. International Standard IEC 62026-1 has been prepared by subcommittee 17B:
30、 Low-voltage switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear. This second edition of IEC 62026-1 cancels and replaces the first edition published in 2000. It represents some general updating without technical changes with regard to the previous edition. The text
31、 of this standard is based on the following documents: CDV Report on voting 17B/1505/CDV 17B/1544/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. 4 62026-1 IEC:2007 This publication has been drafted in accordance
32、 with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 62026, under the general title Low-voltage switchgear and controlgear Controller-device interfaces (CDIs), can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until
33、 the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch” in the data related to the specific publication. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 62026-1 IEC:2007 5 INTRODUCTION The class of controller-d
34、evice interfaces (CDIs) covered in this International Standard includes industrial CDIs for control systems, factory automation and process automation. Industrial CDIs have proliferated to meet specific user needs, but no single CDI meets all needs. The reason for multiple solutions is the wide rang
35、e of physical, usage, information content and configuration requirements. The physical requirements have resulted in CDIs with widely differing signal and line conditioning mechanisms in order to meet distance, node count and environmental considerations. While there is wide variation in CDI technol
36、ogies, there are common components, interfaces and environmental requirements that are specified by this standard. Standardized definitions of these common CDI requirements assist the user to compare and select technologies to match the distance, node count, throughout and installation requirements
37、for a specific application. This standard simplifies the CDI selection process by providing a common structure for generating a specific CDIs IEC standard while also allowing specific interface features and capabilities to be included. Clauses 1 to 8 contain the outline of general requirements that
38、the CDIs IEC standard identifies. Clause 9 contains the test specification. Standardization of CDI aspects also simplifies the task of writing the software for the higher layer functions of industrial control systems, such as supervisory control, operator interface and control strategy programming.
39、For this standard to be complete and usable, it requires the availability of specific CDI standards, which make up the other parts of the IEC 62026 series. 6 62026-1 IEC:2007 LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR CONTROLLER-DEVICE INTERFACES (CDIs) Part 1: General rules 1 Scope This International S
40、tandard applies to interfaces between low-voltage switchgear, controlgear, and controllers (e.g. programmable controllers, personal computers, etc.). This standard does not apply to higher level industrial communication networks that have become known as fieldbuses and are considered by IEC subcommi
41、ttee 65C. The purpose of this standard is to harmonize and define rules, components and requirements of a general nature applicable to industrial CDIs. Those features of the various CDI standards which can be considered as general have therefore been brought together in this part of IEC 62026. For e
42、ach CDI, two main documents are necessary to determine all requirements and tests: a) this part, referred to as “IEC 62026-1” or “Part 1” in the relevant CDI parts covering the various types of CDIs; b) the specific CDI part of the IEC 62026 series. A specific CDI part may omit a general requirement
43、 if it is not applicable, or it may add to it if it is inadequate in the particular case, but it should not deviate from the requirement unless there is substantial technical justification. NOTE Product-specific requirements for products incorporating a CDI are given in the relevant product standard
44、s. These requirements apply in addition to those given in this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
