Data Exchange

IEC TS 62056-8-20:2016(E) specifies a DLMS/COSEM communication profile that can be used in a smart metering system in which the Neighbourhood Networks (NN) are mesh networks. This profile may be considered as an adaptation and extension of the UDP/IP communication profile specified in IEC 62056-9-7:2013. It specifies a number of features essential to the efficient operation of a large scale AMI using mesh NNs.

Provides all the information specific to the management DLMS server of the protocols described in IEC 62056-31, 62056-41 and 62056-51. This publication is a Technical Report type 2.

Describes an architectured application layer used for communication with metering equipment. The associated physical medium and lower layer protocols in a collapsed three-layer model are unspecified. The DLMS protocol is covered by IEC 61334-4-41. This is a Technical Report type 2.

IEC 62056-5-3:2017 specifies the DLMS/COSEM application layer in terms of structure, services and protocols for DLMS/COSEM clients and servers, and defines rules to specify the DLMS/COSEM communication profiles. It defines services for establishing and releasing application associations, and data communication services for accessing the methods and attributes of COSEM interface objects, defined in IEC 62056-6-2 using either logical name (LN) or short name (SN) referencing. This third edition cancels and replaces the second edition of IEC 62056-5-3, published in 2016. It constitutes a technical revision. The significant technical changes with respect to the previous edition are listed in Annex K (Informative).

Specifies the data link layer for connection-oriented, HDLC-based, asynchronous communication profile. This consolidated version consists of the first edition (2002) and its amendment 1 (2006). Therefore, no need to order amendment in addition to this publication. This publication is of high relevance for Smart Grid.

IEC 62056-3-1:2013 describes three profiles for local bus data exchange with stations either energized or not. For non-energized stations, the bus supplies energy for data exchange. Three different profiles are supported: - base profile; - profile with DLMS; - profile with DLMS/COSEM. The three profiles use the same physical layer and they are fully compatible, meaning that devices implementing any of these profiles can be operated on the same bus. The transmission medium is twisted pair using carrier signalling and it is known as the Euridis Bus. This first edition cancels and replaces the first edition of IEC 62056-31, issued in 1999, and constitutes a technical revision. The main technical changes are: - addition of a profile which makes use of the IEC 62056 DLMS/COSEM Application layer and COSEM object model, - review of the data link layer which is split into two parts: a pure Data Link layer; a "Support Manager" entity managing the communication media; - ability to negotiate the communication speed, bringing baud rate up to 9 600 bauds.

Describes hardware and protocol specifications for local meter data exchange. In such systems, a hand-held unit (HHU) or a unit with equivalent functions is connected to a tariff device or a group of devices. This publication is of high relevance for Smart Grid.

IEC 62056-1-0:2014 provides information on the smart metering use cases and on architectures supported by the IEC 62056 DLMS/COSEM series of standards specifying electricity meter data exchange. It describes the standardization framework including: - the principles on which the standards shall be developed; - the ways the existing standards shall be extended to support new use cases and to accommodate new communication technologies, while maintaining coherency; - the aspects of interoperability and information security. It also provides guidance for selecting the suitable standards for a specific interface within the smart metering system.
