IEC 61158-6-14:2014 defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-14, and define the externally visible behavior associated with their transfer. This standard specifies the protocol of the Type 14 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: - corrections of editorial errors; - specification changes for CPF4; - update of the requirements for all conformance classes; - update of the requirements for all conformance services. LIEC 61158-6-14:2014 decrit le protocole mis en place pour definir la representation filaire des primitives de service definies dans la CEI 61158-5-14 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 14, 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 des erreurs editoriales; - modifications de la specification de la CPF4; - mise a jour des exigences de lensemble des classes de conformite; - mise a jour des exigences de lensemble des services de conformite.
