AS IEC 61850.8.1:2025

AS IEC 61850.8.1 – 2025 Edition – Communication networks and systems for power utility automation, Part 8.1: Specific communication service mapping (SCSM) – Mappings to MMS (ISO 9506-1 and ISO 9506-2) and to ISO/IEC 8802-3

AS IEC 61850.8.1:2025 identically adopts IEC 61850-8-1:2011+AMD1:2020, which specifies a method of exchanging time-critical and non-time-critical data through local-area networks by mapping ACSI to MMS and ISO/IEC 8802-3 frames, and defines a standardized method of using the ISO 9506 services to implement the exchange of data. For those ACSI services defined in AS IEC 61850.7.2:2025 that are not mapped to MMS, this part defines additional protocols. It describes real utility devices with respect to their external visible data and behaviour using an object-oriented approach.
