Annotation of standard text IEC 60870-6-503-ed.3.0 :

IEC 60870-6-503:2014 specifies a method of exchanging time-critical control centre data through wide-area and local-area networks using a full ISO compliant protocol stack. It contains provisions for supporting both centralized and distributed architectures. This standard includes the exchange of real-time data indications, control operations, time-series data, scheduling and accounting information, remote program control and event notification. This new edition includes the following significant technical changes with respect to the previous edition: - certain objects were made informative; - services associated with the informative objects were made informative; - certain TASE.2 conformance blocks were made out-of-scope. LIEC 60870-6-503:2014 specifie une methode dechange de donnees a contraintes temporelles fortes, entre centres de conduite, a travers des reseaux longues distances ou des reseaux locaux, en utilisant une pile de protocoles totalement conformes a lISO. Elle contient des dispositions qui satisfont a la fois des architectures centralisees ou des architectures distribuees. La presente norme inclut lechange des indications de donnees en temps reel, des operations de conduite, des donnees par ordre chronologique, des informations de programme ou comptables, des commandes a distance de programmes et des notifications de changement detat. Cette nouvelle edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - certains objets sont devenus informatifs; - les services associes aux objets informatifs sont devenus informatifs; - certains blocs de conformite ont ete retires du domaine dapplication.
