Communication networks and systems for power utility automation - Part 7-2: Basic information and communication structure - Abstract communication service interface (ACSI) (IEC 61850-7-2:2010)

IEC 61850-7-2:2010(E) applies to the ACSI communication for utility automation. The ACSI provides the following abstract communication service interfaces:  - abstract interface describing communications between a client and a remote server;  - and abstract interface for fast and reliable system-wide event distribution between an application in one device and many remote applications in different devices (publisher/sub-scriber) and for transmission of sampled measured values (publisher/subscriber).  Major technical changes with regard to the previous edition are as follows:  - data types not required have been removed,  - service tracking for control blocks have been added,  - security issues are solved by the IEC 62351 series,  - service tracking for control blocks have been added,  - the view concept will be according to the new work on role bases access (RBA),  - security issues are solved by the IEC 62351 series.

IEC 61850-7-2:2010 s’applique aux communications ACSI pour l’automatisation des systèmes. L’ACSI fournit les interfaces abstraites pour les services de communication suivants.
a) Interface abstraite décrivant les communications entre un client et un serveur éloigné pour
– l’accès et l’extraction des données en temps réel,
– la commande de dispositif,
– la consignation et la journalisation des événements,
– le contrôle de groupes de réglages,
– l'autodescription des dispositifs (dictionnaire de données de dispositif),
– typage de données et reconnaissance des types de données, et
– transfert de fichier.
b) Interface abstraite pour la distribution rapide et fiable des événements au niveau du système entre une application d’un dispositif et plusieurs applications éloignées dans des dispositifs différents (d'éditeur/abonné) et la transmission de valeurs mesurées échantillonnées

Ta del IEC 61850 velja za komunikacijo ACSI za avtomatizacijo porabe. ACSI zagotavlja naslednje vmesnike abstraktne komunikacijske storitve:
a) abstraktna povezava, ki opisuje komunikacije med klientom in oddaljenim strežnikom za
- realno časovni dostop do podatkov in priklic;
- nadzor naprave;
- poročanje dogodkov in beleženje;
- nastavitev skupinskega nadzora;
- samo opisovanje naprav (slovar podatkov o napravah);
- tipiziranje podatkov in odkrivanje tipov podatkov ter
- prenos datotek.
b) Abstraktna povezava za hitro in zanesljivo distribucijo dogodkov sistema med aplikacijo v eni napravi in več oddaljenimi aplikacijami v različnih napravah (izdajatelj/naročnik) in za oddajanje vzorčnih merjenih vrednosti (izdajatelj/naročnik).
