scope:

This part of IEC 62746 defines and describes methods and example XML artefacts that can be used to build a conformant adapter to enable interoperation between a utility distributed automation or demand response (DR) system based on the IEC common information model (CIM) and a utility smart grid user interface (SGUI) bridge standard (e.g., IEC 62746-10-1) to a customer facility. A conformant adapter

1) defines mappings for the payloads of request and response messages to pass between the SGUI bridge standard and grid operation systems,

2) requires minimal information sharing between grid operation systems and customer facility management and control systems, and

3) permits independent evolution of necessary standards and technologies used in grid systems and customer facility systems.

The scope is restricted to a method to define payload mappings between any specific CIM profile that contains DR/DER information models and the SGUI bridge standards including IEC 62746-10-1.

NOTE This document addresses a standard method to achieve interoperability for the semantics of message payloads, and does not address broader system issues including but not limited to transport protocols, message envelopes, cybersecurity, presentation, and business model differences. A complete software implementation addresses those broader system issues and, for the grid management side, IEC 62561 and other relevant standards apply.
