Annotation of standard text IEC 61158-6-9-ed.3.0 :
IEC 61158-6-9:2014 defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-9, and define the externally visible behavior associated with their transfer. This standard specifies the protocol of the Type 9 fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545). This third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The main changes are: - Correct Time-difference valid range; - Correct Table 3 state transition; - Include Transparent timeliness class in BNU AREP formal model. LIEC 61158-6-9:2014 decrit le protocole mis en place pour definir la representation filaire des primitives de service definies dans la CEI 61158-5-9 et definir le comportement visible de lexterieur associe a leur transfert. La presente norme specifie le protocole de la couche application de bus de terrain de Type 9, en conformite avec le modele de reference de base OSI (ISO/CEI 7498-1) et la structure de la couche application OSI (ISO/CEI 9545). Cette troisieme edition annule et remplace la deuxieme edition parue en 2010. Elle constitue une revision technique. Les principales modifications sont: - Correction de la plage valide de Time-difference (ecart du temps); - Correction des Passages detats du Tableau 3; - Inclusion de la classe de ponctualite "Transparent" dans le modele formel des points AREP BNU.
