MMS & ASN.1 & XER & XMPP selected as the second SCSM of IEC 61850

The second SCSM for the ACSI Client-Server information exchange service models will be the mapping of the ACSI service models to MMS ASN.1 XER and XMPP. IEC TC 57 just released the 122 page document 57/1497/DC:

Draft IEC 61850-80-3 TR, Communication networks and systems for power utility automation – Part 80-
3: Mapping to web protocols – Requirement analysis and technology assessment

The document mainly lists the crucial needs and why the mapping to “MMS ASN.1 XER and XMPP” has been chosen to be published as IEC 61850-8-2 soon.

Chapter 7 presents the future SCSM 8-2, including an overview of the main selected technology: XMPP.

The following goals have been particularly considered for the definition of this SCSM:

  • Identify a single profile supporting all the services required by the domains and defined today in ACSI.
  • Cover the full life cycle of a IEC 61850 system, in collaboration with the System Management work in WG10 (from configuration, through conformance testing, down to maintenance). For this purpose, the present document may recommend some changes in other parts of IEC 61850 like part 6, part 10, etc.
  • Deploy cyber-security to ensure a secure environment (in conjunction with IEC TC 57 WG 15 work).
  • Propose rules for cohabitation with other mappings such as IEC 61850-8-1 and IEC 61850-9-2, and possibly recommend communication profiles depending on specific application context (pole-top equipment, inside DER, connection of DER, …).

Check with your national IEC TC 57 mirror committee for a copy of the above mentioned document.

Congratulation for the tremendous success of the web service mapping team!!! Great work!

That means: IEC 61850 will be the preferred solution in substations and many applications outside!!
