IEC 61850-8-3 reaches Committee Draft stage: the new mapping uses WebSocket, JSON and ASN.1
The International Electrotechnical Commission has taken another step toward publishing a new part of the IEC 61850 series. On 4 September 2026, the IEC published Committee Draft 57/2980/CD of IEC 61850-8-3 — a new Specific Communication Service Mapping (SCSM) based on the technologies WebSocket, JSON and ASN.1. The IEC 61850 information model itself does not change: the existing services simply gain a new way of being mapped onto a modern communication stack. The commenting period for national committees ends on 30 October 2026.
