Annotation of standard text IEC 62541-10-ed.3.0 :

IEC 62541-10:2020 is available as IEC 62541-10:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62541-10:2020 defines the information model associated with Programs in the OPC Unified Architecture. This includes the description of the NodeClasses, standard Properties, Methods and Events and associated behaviour and information for Programs. The complete Address Space model including all NodeClasses and Attributes is specified in IEC 62541-3. The Services such as those used to invoke the Methods used to manage Programs are specified in IEC 62541 4. This third edition cancels and replaces the second edition published in 2015. This edition includes several clarifications and in addition the following significant technical changes with respect to the previous edition: a) Changed ProgramType to ProgramStateMachineType. This is in line with the NodeSet (and thus implementations). In ProgramDiagnosticDataType: changed the definition of lastInputArguments and lastOutputArguments and added two additional fields for the argument values. Also changed StatusResult into StatusCode. Created new version of the type to ProgramDiagnostic2DataType. b) Changed Optional modelling rule to OptionalPlaceHolder for Program control Methods. Following the clarification in IEC 62541-3, this now allows subtypes (or instances) to add arguments.
IEC 62541-10:2020 est disponible sous forme de IEC 62541-10:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis ledition precedente.
IEC 62541-10:2020 definit le modele dinformation associe avec des Programmes dans lArchitecture unifiee OPC. Elle comprend la description des NodeClasses, des Proprietes, Methodes et Evenements normalises et du comportement associe ainsi que des informations relatives aux Programmes. Le modele despace dadressage complet, comprenant toutes les NodeClasses et tous les Attributs, est specifie dans lIEC 62541-3. Les Services tels que ceux utilises pour invoquer les Methodes appliquees pour gerer les Programmes sont specifies dans lIEC 62541-4. Cette troisieme edition annule et remplace la deuxieme edition parue en 2015. Cette edition inclut plusieurs clarifications ainsi que les modifications techniques majeures suivantes par rapport a ledition precedente: a) remplacement de ProgramType par ProgramStateMachineType, conformement au NodeSet (et donc aux mises en ouvre). Dans le programme ProgramDiagnosticDataType, modification des definitions de lastInputArguments et lastOutputArguments, et ajout de deux champs complementaires pour les valeurs darguments. Remplacement egalement de StatusResult par StatusCode. Creation dune nouvelle version du type de ProgramDiagnostic2DataType; b) remplacement de la regle de modelisation Facultative par OptionalPlaceHolder pour les Methodes de Commande de Programme. Ceci fait suite a la clarification apportee dans lIEC 62541-3, et permet aux sous-types (ou instances) dajouter des arguments.
