    27、 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 and electronic fields. To this end

    28、 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 committees; any IEC National Commi

    29、ttee 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 for Standardization (ISO) in ac

    30、cordance 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 committee has representation from all

    31、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 accurate, IEC cannot be held res

    32、ponsible 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 regional publications. Any diverge

    33、nce 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, in some areas, access to IEC mar

    34、ks 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 agents including individual expert

    35、s 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, or reliance upon, this IEC Pub

    36、lication 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 of the elements of this IEC Pub

    37、lication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61987-24-3 has been prepared by subcommittee 65B: Measurement and control devices, of IEC technical committee 65: Industrial-process measurement,

    38、control and automation. The text of this International Standard is based on the following documents: CDV Report on voting 65B/1037/CDV 65B/1066/RVC Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. 4 IEC

    39、61987-24-3:2017 IEC 2017 This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 61987 series, published under the general title Industrial-process measurement and control Data structures and elements in process equipment catalogues, can be fo

    40、und on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, repl

    41、aced by a revised edition, or amended. IEC 61987-24-3:2017 IEC 2017 5 INTRODUCTION The exchange of product data between companies, business systems, engineering tools, data systems within companies and, in the future, control systems (electrical, measuring and control technology) can run smoothly on

    42、ly when both the information to be exchanged and the use of this information has been clearly defined. Prior to IEC 61987, requirements on process control devices and systems were specified by customers in various ways when suppliers or manufacturers were asked to quote for suitable equipment. The s

    43、uppliers in their turn described the devices according to their own documentation schemes, often using different terms, structures and media (paper, databases, CDs, e-catalogues, etc.). The situation was similar in the planning and development process, with device information frequently being duplic

    44、ated in a number of different information technology (IT) systems. Any method that is capable of recording all existing information only once during the planning and ordering process and making it available for further processing, gives all parties involved an opportunity to concentrate on the essen

    45、tials. A precondition for this is the standardization of both the descriptions of the objects and the exchange of information. IEC 61987 (all parts) propose a method for standardization which will help both suppliers and users of process control equipment to optimize workflows both within their own

    46、companies and in their exchanges with other companies. Depending on their role in the process, engineering firms can be considered here to be either users or suppliers. The method specifies process control equipment by means of blocks of properties. These blocks are compiled into lists of properties

    47、 (LOPs), each of which describes a specific equipment (device) type. IEC 61987 (all parts) covers both properties that can be used in an inquiry or a proposal and detailed properties required for integration of the equipment in computer systems for other tasks. Part 10 of IEC 61987 defines structure

    48、 elements for constructing lists of properties for electrical and process control equipment in order to facilitate automatic data exchange between any two computer systems in any possible workflow, for example engineering, maintenance or purchasing workflow and to allow both the customers and the su

    49、ppliers of the equipment to optimize their processes and workflows. Part 10 also provides the data model for assembling the LOPs. Part 11 of IEC 61987, while specifying a generic structure for measuring equipment, provides several important detail descriptions, such as the handling of composite devices that are also required for LOPs describing devices of other areas like the automated valves. Part 21 of IEC 61
