31、mation elements 57(C0)67 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 cooperation on all questions conce
32、rning standardization in 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 p
33、reparatory work. International, 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
34、 organizations. 2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on which all the National Committees having a special interest therein are represented, express, as nearly as possible, an international consensus of opinion on the subjects dealt
35、with. 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 International Standards transparently to the maximum extent possible in their national and regional stand
36、ards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 3) They have the form of recommendations for international use published in the form of standards, International Standard IEC 870-514 has been prepared by IEC t

45、 data in tele- control systems. 1 Scope and object This section of IEC 870-5 applies to telecontrol equipment and systems with coded bit serial data transmission for monitoring and controlling geographically widespread processes. This section of IEC 870-5 gives rules for defining information element
46、s and presents a set of information elements, in particular of digital and analog process variables, that are frequently used in telecontrol applications. Clause 4 presents syntactic rules for defining application specific information elements. These rules comprise methods for semantic declarations,
47、 that is assignments of the functional interpretation of the defined information fields. Clause 5 applies the declaration method to the basic data types defined in Clause 4 and introduces particular subtypes of data. Clause 6 presents a set of information elements that are frequently used in telecon
48、trol applications. These elements and the mentioned recommended applications for these elements are recommendations only. Definitive declarations of information elements have to be fixed in application profiles. Single information elements, sequences or combinations of information elements may form an information object that is identified by an object address and by an object structures specification described in IEC 870-5-3.
