IEC 61850-9-2 First edition 2004-04. Communication networks and systems in substations - Part 9-2: Specific Communication Service Mapping (SCSM) - Sampled values over ISO/IEC 8802-3 Reference

IEC 2004, 3, rue de Varembé, PO Box 131, CH-1211 Geneva 20, Switzerland- 34 p.
This part of IEC 61850 defines the Specific Communication Service Mapping (SCSM) 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. Each SCSM consists of three parts:
– a specification of the communication stack being used,
– the mapping of the abstract specifications of IEC 61850-7 on the real elements of the stack
being used, and
– the implementation specification of functionality, that is not covered by the stack being
used.
