18、n engineering tools for field devices FOREWORD 1) The 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 quest

19、ions concerning standardization in the electrical and 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(

20、s)”). Their preparation is entrusted to technical committees; 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 coll

21、aborates closely with the International Organization 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

22、on the relevant subjects since each technical committee 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 ensur

23、e 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) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to

24、the maximum extent possible in their national and regional 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

25、 bodies provide conformity assessment services and, 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 attac

26、h 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 (including legal fees)

27、 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 this publication

28、 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. The main task of IEC technical committees is to prepare International Standards. However,

29、 a technical committee may propose the publication 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 61804-6, which is a Technical Report, has been prepared by subcommittee 65E:

30、 Devices and integration in enterprise systems, of IEC technical committee 65: Industrial-process measurement, control and automation. 4 TR 61804-6 IEC:2012(E) The text of this technical report is based on the following documents: Enquiry draft Report on voting 65E/212A/DTR 65E/239/RVC Full informat

31、ion on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 61804 series, under the general title Function blocks (FB

32、) for process control Electronic device description language (EDDL), can be found on the IEC website. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated at the time of the next edition. The committee has decide

33、d 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 edition, or amended.

34、 A bilingual version of this publication may be issued at a later date. TR 61804-6 IEC:2012(E) 5 INTRODUCTION The information contained in this part of IEC 61804 is provided for information only and is not part of the IEC 61804-3 requirements. NOTE 1 ANSI/ISA-61804-3 (104.00.01):2007 is an equivalen

35、t to IEC 61804-3:2006. The need for device integration has grown significantly in recent years. The combination of open systems, growth and mix of bus protocols, more intelligent devices and more sophisticated and complex devices has increased the requirements for integrating these devices in a sing

36、le tool. The purpose of this technical report is to investigate if the IEC 61804-3 technology meets the requirements of NAMUR NE 105. NAMUR is an international users association of automation technology in the process industries (www.namur.de). Recommendation NE 105 prepared by working group 2.6: Fi

37、eldbus, contains requirements for device integration technologies such as the electronic device description language (EDDL). From experience, control system manufacturers and plant operations do not permit third-party software to be installed on DCS server, engineering station, or operator consoles

38、but rather only on separate application stations. One of the objectives of the EDDL standard is to reduce or minimize the need for third-party software to be installed. The question this technical report addresses is if EDDL can meet device integration requirement without the need for software drive

39、rs. Most NAMUR NE 105 requirements are concerned with the long-term viability of the system and the ease of managing the system. A few requirements are concerned with consistency between different protocols, device types, and manufacturers. EDDL meets all requirements of NAMUR NE 105. Most requireme

40、nts are met by virtue of the fact that an EDD file is a compressed text, not a software. Early EDDL, before enhancements were specified in IEC 61804-3:2006, met most but not all of the NAMUR NE 105 requirements. NOTE 2 A system combining EDDL with other technologies that do not meet NAMUR NE 105, ov

41、erall will not meet the requirements of NAMUR NE 105. EDDL is a language to write the electronic device description (EDD) files. An EDD file describes how an engineering software can integrate a fieldbus device. EDD files provides information which command to send to a field device to read or to wri

42、te information, how to decode the response, and how to display the information. The main focus is on investment protection in the face of modern information technology because automation technology users cannot tolerate constant upgrades, updates, and releases that is, long-term viability for system

43、s and devices without undue maintenance effort. Other major points include ease of keeping systems up to date with new device types and versions, robustness, and uniform display of devices from different manufacturers, for a human interface that is intuitive and easy to learn. The NE 105 recommendat

44、ion provided important input for developing the enhancements made to EDDL. 6 TR 61804-6 IEC:2012(E) FUNCTION BLOCKS (FB) FOR PROCESS CONTROL ELECTRONIC DEVICE DESCRIPTION LANGUAGE (EDDL) Part 6: Meeting the requirements for integrating fieldbus devices in engineering tools for field devices 1 Scope
