26、he 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 a

27、nd 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 c

28、ommittees; 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 Organizatio

29、n 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 commi

30、ttee 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

31、 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 r

32、egional 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,

33、 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 a

34、gents 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 o

35、f, 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 som

36、e 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. However, a technical committee may propose the publication

37、of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC 62685, which is a technical report, has been prepared by subcommittee 65C: Industrial networks, of IEC technical committee 65:

38、Industrial-process measurement, control and automation. This bilingual version (2013-04) corresponds to the monolingual English version, published in 2010-12. TR 62685 IEC:2010 5 The text of this technical report is based on the following documents: Enquiry draft Report on voting 65C/610/DTR 65C/626

39、/RVC Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The commi

40、ttee has decided that the contents of this publication will remain unchanged until the stability 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 editi

41、on, or amended. 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 should therefore print this document using a colour printer. 6 TR 62685 IEC:2010 INTRODUCTI

42、ON During the development of IEC 61784-3:2010, the need was recognized for a separate document covering environmental tests, proofs and information checks, which were currently specified in the German document GS-ET-26 37 1 . This document has been one of the starting points for IEC 61784-3 and most

43、 of its contents have been already taken into account in IEC 61784-3. The material related to environmental tests, proofs and information checks has been transformed, updated and supplemented into this new document. NOTE IEC 61784-3 explains the relevant principles for functional safety communicatio

44、ns with reference to IEC 61508 series and specifies several safety communication layers (profiles and corresponding protocols) based on the communication profiles and protocol layers of IEC 61784-1, IEC 61784-2 and the IEC 61158 series. The combination of the IEC 61508 series 2 , with its new view o

45、n complete safety functions, and of the FSCPs in the IEC 61784-3 series, eases the implementation of safety functions. Further benefits can be achieved, if the environmental conditions can be defined and harmonized for FSCP devices. The objective of this document is to specify the requirements for F

46、SCP devices on how to fulfill environmental and deployment conditions. It addresses the needs of designers, manufacturers, assessment bodies, and test laboratories. Figure 1 provides a basic overview on safety functions, FSCP devices and the impact of the environment. It demonstrates the necessity o

47、f harmonized environmental requirements. Figure 1 Environmental view on safety functions _ 1Numbers in square brackets refer to the Bibliography. 2In this Technical Report, “IEC 61508” is used for “IEC 61508 series”.

48、nt guideline for safety devices using IEC 61784-3 functional safety communication profiles (FSCPs) 1 Scope This Technical Report provides information about the assessment aspects of safe communication such as test beds, proof of increased interference immunity (EMC for functional safety), electrical

49、 safety, and other environmental requirements. This document is only applicable to safety devices for functional safety communication which are developed according to IEC 61508 and IEC 61784-3. NOTE This document does not cover the more complex aspects of preserving existing devices and applications in the field and migration from safety rules before IEC 61508. The scope covers general i
