The two service mappings for IEC 61850 are IEC 61850-8-1 (MMS) and IEC 61850-8-2 (MMS/XML). The mapping IEC 61850-8-1 is in operation from the first days when IEC 61850 was implemented and used ... all over ... in millions of devices and thousands of systems. Ok ... perfect.
Why is there an need for an additional service mapping in IEC 61850 (IEC 61850-8-3)?
Simply because of the complex and tricky mapping to MMS (Manufacturing Message Specification, ISO 9506).
IEC 61850-8-3
Communication networks and systems for power utility automation –
Specific Communication Service Mapping (SCSM) –
Mapping to Direct Message Specification (DMS), JSON Encoding Rules, and WebSockets
In order to explain details of the new approach to be used for the new work item proposal IEC 61850-8-3 I have produced a 17 minute video.
It is likely that this will become a major shift in the use of IEC 61850.
Enjoy!
