DLMS/COSEM (IEC 62056, EN13757-1) is the global standard for smart energy metering, control and management. It specifies an object-oriented data model, an application layer protocol and media-specific communication profiles. DLMS/COSEM comprises three key components:
COSEM stands for Companion Specification for Energy Metering. It is an interface model for communicating with energy metering equipment, providing a view of the functionality available through the communications interfaces.
data exchange – The DLMS/COSEM suite – Part 5-3: DLMS/COSEM application layer. To bring the changes in Green Book Editions 8.3, 9 and 10 to international standardisation, updates to IEC 62056-5-3:2017 will be initiated by IEC TC13 WG14.
25 Αυγ 2009 · The DLMS / COSEM standard suite has been developed based on two strong and proven concepts: object modelling of application data and the Open Systems Interconnection (OSI) model. This allows covering the widest possible range of applications and communication media.
24 Νοε 2015 · Gurux DLMSDirector is an easy-to-use application to communicate with DLMS/COSEM smart meters. You can connect to one or more physical DLMS devices with GXDLMSDirector and you can select whether to read values from all listed devices, or one of them, or just a single object of a single device.
COSEM, short for Companion Specification for Energy Metering, represents a standardized framework within the DLMS® (Device Language Message Specification) ecosystem. It serves as a comprehensive set of specifications and guidelines for facilitating communication and data exchange between utility meters and data collection systems.
Being an object-oriented open international standard, DLMS/COSEM is the de-factor AMR standard in most part of the world. It is well organized and facilitates the interoperability among devices and systems from different vendors.
