Description / Abstract:

This Standard defines a Table structure for utility application data to be passed between an End Device and any other device. It neither defines device design criteria nor specifies the language or protocol used to transport that data. The Tables defined in this Standard represent a data structure that shall be used to transport the data, not necessarily the data storage format used inside the End Device.


The Utility Industry has a need for a Standard that provides an interoperable "plug-and-play" environment for field metering devices. The purpose of this Standard is to define the framework and data structures for transporting Utility End Device data to and from End Devices and for use by enterprise systems.

This Standard is intended to accommodate the concept of an advanced metering infrastructure, such as that identified by the Office of Electricity Delivery and Energy Reliability of the U.S. Department of Energy; the Smart Metering Initiative of the Ontario Ministry of Energy (Canada); and the stated requirements of Measurement Canada for the approval of a metering device for use in Canada.

This Standard is to provide a uniform, structured, and adaptive data model, such that Utility End Devices and ancillary devices (e.g., home appliances and communication technology) can operate in a "plug-andplay" and multisource enterprise Advanced Metering Infrastructure (AMI) environment.

This Standard extends the definitions provided by IEEE Std 1377-1998 to include provisions for enterprise-level asset management, data management, and uniform data exchange capability, through the use of common and managed Extensible Markup Language (XML)/Table Definition Language (TDL) and XML/Exchange Data Language (EDL) End Device Class models.
