18、LANGUAGE (EDDL) 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 questions concerning standa
19、rdization 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(s)”). Their preparatio
20、n 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 collaborates closely with t
21、he 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 on the relevant subject
22、s 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 ensure that the technical co
23、ntent 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 the maximum extent poss
24、ible 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 bodies provide conform
25、ity 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 attach to IEC or its directo
26、rs, 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) and expenses arising o
27、ut 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. 9) Attention is drawn
28、 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, a technical committee
29、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 62795, which is a technical report, has been prepared by subcommittee 65E: Devices and integration
30、in enterprise systems, of IEC technical committee 65: Industrial-process measurement, control and automation. The text of this technical report is based on the following documents: Enquiry draft Report on voting 65E/240/DTR 65E/330/RVC Full information on the voting for the approval of this technica
31、l 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. TR 62795 IEC:2013(E) 5 The committee has decided that the contents of this publication will remain unchanged until the stability date indic
32、ated 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. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour
33、 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 62795 IEC:2013(E) INTRODUCTION At present, there are two Inte
34、rnational Standards for device integration that describe the properties of automation system components to be used in host systems. They are IEC 61804 for electronic device description language (EDDL) and IEC 62453 for field device tools (FDT), with both standards having their own characteristics. T
35、he number of manufacturers and users using EDDL or FDT technologies is increasing, and investment in both of them is therefore increasing too. EDDL technology enables the integration of real product details using the tools of the engineering life cycle and specifies EDDL as a generic language for de
36、scribing the properties of automation system components. EDDL technology allows to transfer the properties of a device to a data set, called electronic device description (EDD), that can be interpreted by configuration tools in a host system. EDD files, representing the behavior and attributes of a
37、device, can be stored in the field device or control system. The interaction between a field device and a control system uses various communication protocols such as specified in IEC 61784-1, CP 1-1 (FF) or IEC 61784-1, CP 9-1 (HART 1 ). FDT is an open and independent software interface specificatio
38、n. An FDT specification describes software interface and relationships within the framework of the project (FDT container, FDT frame applications) and device software components in a Device Type Manager (DTM). An FDT framework is independent from the devices and fieldbus system, while the DTM depend
39、s on specific device and fieldbuses. Both technologies are supported by automation vendors and users, so that there is a need to generate a DTM based on an EDD as long as the field device integration (FDI) technology is not published as an International Standard. FDI (IEC 62769) covers device integr
40、ation and device management technology, combining base concepts and technology aspects of the EDDL (IEC 61804), FDT (IEC 62543) and OPC UA (IEC 62541-1). The combination of those different proven technologies ensures a secure life cycle and the ability to address all challenges of device integration
41、 and device management in a scalable manner. EDDL and FDT are complimentary in a way that an EDDL can be converted into an FDT-DTM. As long as FDI is not available, converting EDD into a DTM helps to combine the two standards and use EDDs in an FDT frame environment in case there is no specific DTM
42、available. The conversion criterion is based on EDDL and FDT technologies. _ 1HART is an example of a suitable product available commercially. This information is given for the convenience of users of this document and does not constitute an endorsement by IEC of this product. TR 62795 IEC:2013(E) 7
43、 INTEROPERATION GUIDE FOR FIELD DEVICE TOOL (FDT) / DEVICE TYPE MANAGER (DTM) AND ELECTRONIC DEVICE DESCRIPTION LANGUAGE (EDDL) 1 Scope This Technical Report provides the general requirements for converting an EDD into a DTM. Using this TR, an FDT/DTM developer can develop an EDD-DTM conversion tool
44、 that can be used to import, parse, and manage EDD to generate the corresponding DTM. A conversion tool versus a DTM written independent of an EDD helps the DTM generation to maintain consistency in function, data and presentation styles. 2 Normative references The following documents, in whole or i
