CSA ISO/IEC 10192-3:19
Information technology — Home electronic system (HES) interfaces — Part 3: Modular communications interface for energy management (Adopted ISO/IEC 10192-3:2017, first edition, 2017-11)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This part of IEC 10192 specifies a UCM (Universal Communications Module) that transfers energy management data via a home network between an end-device and an energy management agent (specified in ISO/IEC 15067-3) or an energy service provider. This document specifies the mechanical, electrical and logical characteristics of the interfaces of UCM to an end-device (hereafter referred to as an SGD – Smart Grid Device) and a choice of interfaces to a home communications network.
This document specifies the physical and data-link characteristics of the interface between the UCM and the SGD, along with certain higher-layer and application layer elements as needed to assure interoperability over a broad range of device capabilities. It specifies a mechanism through which network, transport and application layer messages specified in other documents listed in this document may be passed through the interface. For those end devices that cannot process one of the pass-through command sets, a Simple Protocol is specified according to the OSI (Open System Interconnect) reference model (ISO/IEC 7498-1) including application layer messaging for energy management.
The UCM specified in this document is intended to be installable by the purchaser, home occupant or professional installer. The connectors are integrated in a way that allows for easy, plug-in installation. However, the manufacturer may choose to pre-install a module during production or have installation handled by a manufacturer representative or professional installer.
The scope of this document does not include safety related construction, performance, marking or instruction requirements. UCM products should additionally comply with applicable product safety standard(s). Examples of such standards are presented in Annex G.
NOTE Some regulatory authorities require that appliances intended for participation in energy management, such as thermostats, be user installable.
