Communication networks and systems in substations - Part 9-1: Specific Communication Service Mapping (SCSM) - Sampled values over serial unidirectional multidrop point to point link

Lays down the specific communication service mappings for the communication between bay and process level; specifies a mapping on a serial unidirectional multidrop point to point link in accordance with IEC 60044-8. Applies to the communication between merging units of electronic current or voltage-transformers and bay devices such as protection relays.This publication is of core relevance for Smart Grid.

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.
