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.

Réseaux et systèmes de communication pour l'automatisation des systèmes électriques - Partie 9-2: Mise en correspondance des services de communication spécifiques (SCSM) - Valeurs échantillonnées sur l'ISO/CEI 8802-3

La CEI 61850-9-2:2011 définit la mise en correspondance des services de communication spécifiques pour la transmission des valeurs échantillonnées, conformément à la spécification abstraite de la CEI 61850-7-2. La mise en correspondance est celle du modèle abstrait sur une pile mélangée, utilisant l'accès direct à une liaison ISO/CEI 8802-3 pour la transmission des échantillons, en conjonction avec la CEI/TR 61850-8-1. Les modifications principales par rapport à la première édition sont les suivantes: - l'adjonction d'une couche optionnelle de redondance de liaison; - la redéfinition des champs 'reserved' dans la couche de liaison; - l'évolution des composants USVCB et MSVCB; - l'évolution de l'encodage relatif à la transmission de la mémoire tampon des valeurs échantillonnées.

Komunikacijska omrežja in sistemi v postajah - 9-2. del: Preslikave posebne komunikacijske storitve (SCSM) - Vzorčne/odčitane vrednosti po ISO/IEC 8802-3

Ta del standarda IEC 61850 določa preslikave posebne komunikacijske storitve (SCSM) za prenos vzorčnih/odčitanih vrednosti v skladu z abstraktno specifikacijo iz standarda IEC 61850-7-2. To je preslikava abstraktnega modela na mešani sklad z neposrednim dostopom do povezave iz standarda ISO/IEC 8802-3 za prenos vzorcev v kombinaciji s standardom IEC 61850-8-1. Vse preslikave posebne komunikacijske storitve so sestavljene iz treh delov: – specifikacija uporabljenega komunikacijskega sklada, – preslikava abstraktnih specifikacij iz serije IEC 61850-7 o realnih elementih uporabljenega sklada in – specifikacija izvajanja funkcionalnosti, ki je ne zajema uporabljeni sklad.
