18、nical 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 thi
19、s 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 committees; any IEC National
20、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 for Standardization (ISO)
21、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 committee has representation from
22、 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 accurate, IEC cannot be hel
23、d 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 regional publications. Any di
24、vergence 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 IE
25、C 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 agents including individual e
26、xperts 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 IE
27、C 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 of the elements of this IE
28、C 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 62745 has been prepared by IEC technical committee 44: Safety of machinery Electrotechnical aspects. The text of this standard is based on th
29、e following documents: FDIS Report on voting 44/783/FDIS 44/785/RVD 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. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. IEC
30、62745:2017 IEC 2017 5 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, replac
31、ed by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour 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

The functionality of a CCS and the way in which it interfaces with the overa
33、ll machine control system can therefore affect the safety of the machinery. IEC 62745 specifies requirements for the functionality of a CCS that is interfaced with or is part of a machine control system for use as an operator control station on a machine. The extent to which the functionality of a C
34、CS is relied upon to minimise risk on a machine is a key selection criterion. It is therefore important to select a CCS that provides suitable control functions with an appropriate safety integrity in accordance with the risk assessment at the machine. In some particular applications, the requiremen
35、ts for a CCS can exceed those specified in this document. IEC 62745:2017 IEC 2017 7 SAFETY OF MACHINERY REQUIREMENTS FOR CABLELESS CONTROL SYSTEMS OF MACHINERY 1 Scope This standard specifies requirements for the functionality and interfacing of cableless (for example, radio, infra-red) control syst
36、ems that provide communication between operator control station(s) and the control system of a machine. Specific requirements are included for such operator control stations that are portable by the operator. NOTE The part of the cableless control system that is used as an operator control station i
37、s sometimes referred to as the transmitter and the part that interfaces with the machine control system is sometimes referred to as the receiver. However, to take account of the possibility of bi-directional communication, this standard refers to these individual parts as the remote station and the
38、base station respectively. This document does not deal with cableless communication between parts of a machine(s) that are not operator control stations. This document is not intended to specify all of the requirements that are necessary for the design and construction of a cableless control system.
39、 For example, it does not specify communication protocols, frequency or bandwidth aspects, nor the full range of constructional requirements such as impact resistance, ingress protection, electromagnetic compatibility, etc. The provisions of this document are intended to be applied in addition to th
40、e requirements for electrical equipment in the IEC 60204-1. This document is a type-B2 standard as stated in ISO 12100. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
