Anotation

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. La CEI 61850-9-2:2011 definit la mise en correspondance des services de communication specifiques pour la transmission des valeurs echantillonnees, conformement a la specification abstraite de la CEI 61850-7-2. La mise en correspondance est celle du modele abstrait sur une pile melangee, utilisant lacces direct a une liaison ISO/CEI 8802-3 pour la transmission des echantillons, en conjonction avec la CEI/TR 61850-8-1. Les modifications principales par rapport a la premiere edition sont les suivantes: - ladjonction dune couche optionnelle de redondance de liaison; - la redefinition des champs "reserved" dans la couche de liaison; - levolution des composants USVCB et MSVCB; - levolution de lencodage relatif a la transmission de la memoire tampon des valeurs echantillonnees.
