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.
