Foreword The text of document 13/1387/FDIS, future edition 2 of IEC 62056-53, prepared by IEC TC 13, Electrical energy measurement, tariff- and load control, was submitted to the IEC-CENELEC parallel vote and was approved by CENELE
13、C as EN 62056-53 on 2007-02-01. This European Standard supersedes EN 62056-53:2002. The main changes with respect to EN 62056-53:2002 are as follows: the protocol of the COSEM-RELEASE service has been changed: depending on the communication profile used, these services may rely on the ACSE A_RELEASE
14、 services; the parsing order of the AARQ APDU has been changed; handling of repeated application association requests has been simplified; the Service_Class parameter of the COSEM-OPEN service is now linked to the response allowed field of the xDLMS-Initiate.request APDU; the Service_Class parameter
15、 of COSEM services for data exchange using LN referencing is now linked to bit 6 of the Invoke-Id-And-Priority parameter; a new, optional EXCEPTION APDU has been introduced. The server may send back this APDU after an erroneous service request; a general part about using the COSEM application layer
16、in various communication profiles has been added; the description of using the COSEM Application layer in the 3-layer, connection-oriented, HDLC based communication profile has been amended; a new, TCP-UDP/IP based communication profile has been defined. The following dates were fixed: latest date b
17、y which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2007-11-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2010-02-01 The International Electrotechnical Commission (IEC) and
18、 CENELEC draw attention to the fact that it is claimed that compliance with this International Standard / European Standard may involve the use of a maintenance service concerning the stack of protocols on which the present standard IEC 62056-53 / EN 62056-53 is based. The IEC and CENELEC take no po
19、sition concerning the evidence, validity and scope of this maintenance service. The provider of the maintenance service has assured the IEC that he is willing to provide services under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the s
20、tatement of the provider of the maintenance service is registered with the IEC.
