16、6-9-1:2016 IEC 2016 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ ELECTRICITY METERING DATA EXCHANGE THE DLMS/COSEM SUITE Part 9-1: Communication profile using web-services to access a DLMS/COSEM server via a COSEM Access Service (CAS) FOREWORD 1) The International Electrotechnical Commission (IEC) is
17、 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 this end and in addition to
18、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 Committee interested in t
19、he 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) in accordance with conditi
20、ons 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 all interested IEC Nation
21、al 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 held responsible for the way
22、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 divergence between any IEC P
23、ublication 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 IEC marks of conformity. IEC
24、 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 experts and members of its
25、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 IEC Publication or any other
26、 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 IEC Publication may be the s
27、ubject 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. In exceptional circumstances, a technical committee may propose the publication of a technical specification when
28、 the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Tech
29、nical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC TS 62056-9-1, which is a technical specification, has been prepared by IEC technical committee 13: Electrical energy measurement and control. PD IE
30、C/TS 62056-9-1:2016IEC TS 62056-9-1:2016 IEC 2016 5 The text of this technical specification is based on the following documents: Enquiry draft Report on voting 13/1641/DTS 13/1662/RVC Full information on the voting for the approval of this technical specification can be found in the report on votin
31、g indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62056 series, published under the general title Electricity metering data exchange The DLMS/COSEM suite, can be found on the IEC website. The committee
32、has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed,
33、withdrawn, replaced 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 it
34、s contents. Users should therefore print this document using a colour printer.

35、 (CAS) 1 Scope This part of IEC 62056, which is a Technical Specification, defines how DLMS/COSEM servers can be accessed from a COSEM Access Client via an intermediate COSEM Access Service (CAS) providing Web services. The DLMS/COSEM server contains an application server supporting the data model o
36、f IEC 62056-6-1 / IEC 62056-6-2 and the application layer of IEC 62056-5-3. The underlying communication layers between the CAS and the DLMS/COSEM server are not covered by this specification. However, it is assumed that a profile standard exists describing how the underlying communication technolog
37、y is used in conjunction with IEC 62056-6-1/ IEC 62056-6-2 and IEC 62056-5-3. The Web services defined in this Technical Specification concern the G2 interface according to the architecture defined in IEC 62056-1-0. The contents of this document define the Web services between the COSEM Access Clien
38、t and the COSEM Access Service (CAS) as shown in Figure 1.

49、hown in Figure 2. Where the HES acts as COSEM Access Client, the NNAP provides the COSEM Access Service (CAS) and the DLMS/COSEM server corresponds to the metering device. The Web services defined in this TS concern the G2 interface. Typically, the communication technology used in the NN is not the same as the communication technology used in the WAN; i.e. the NN does not necessarily support IP based communication.
