Communication networks and systems for power utility automation - Part 9-2: Specific communication service mapping (SCSM) - Sampled values over ISO/IEC 8802-3

IEC 61850-9-2:2011 defines the specific communication service mapping for the transmission of sampled values according to the abstract specification in IEC 61850-7-2.

The mapping is that of the abstract model on a mixed stack using direct access to an ISO/IEC 8802-3 link for the transmission of the samples in combination with IEC 61850-8-1.

Main changes with respect to the first edition are:

  • Addition of an optional link redundancy layer;
  • Redefinition of "reserved" fields in link layer;
  • Evolution of USVCB and MSVCB components;
  • Evolution of encoding for the transmission of the sampled value buffer.
