IEC 61850-9-2:2011

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 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.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any e
