Edition date: 2012-11-07
In Force
Available languages: English, French
Summary: IEC 61499-1:2012 defines a generic architecture and presents guidelines for the use of function blocks in distributed industrial-process measurement and control systems (IPMCSs). This architecture is presented in terms of implementable reference models, textual syntax and graphical representations. The models given in this standard are intended to be generic, domain independent and extensible to the definition and use of function blocks in other standards or for particular applications or application domains. It is intended that specifications written according to the rules given in this standard be concise, implementable, complete, unambiguous, and consistent. This second edition cancels and replaces the first edition published in 2005 an constitutes a technical revision. It includes the significant technical changes with respect to the previous edition related to: Execution control, Temporary variables, Service sequences, the syntax for mapping of FB instances, the Syntax for definition of segment types, the Function block types for interoperation with programmable controllers and the READ/WRITE management commands.

La CEI 61499-1:2012 définit une architecture générique et présente des lignes directrices pour l'utilisation de blocs fonctionnels dans des systèmes de mesure et de commande dans les processus industriels distribués (IPMCS). Cette architecture est présentée en termes de modèles de référence pouvant être mis en oeuvre, de syntaxe textuelle et de représentations graphiques. Les modèles donnés dans la présente norme sont censés être génériques, indépendants vis-à-vis de tout domaine et extensibles à la définition et à l'utilisation de blocs fonctionnels dans d'autres normes ou pour des applications particulières ou des domaines d'application particuliers. L'intention est de faire en sorte que les spécifications écrites selon les règles données dans la présente norme soient concises, réalisables, complètes, non ambiguës et cohérentes. Cette deuxième édition annule et remplace la première édition parue en 2005 et constitue une révision technique. Cette édition inclut des modifications techniques majeures liées aux: terme contrôle d'exécution, variables temporaires, séquences de service, syntaxe pour le mapping des instances FB, syntaxe relative à la définition des types de segment, commandes de gestion READ/WRITE.
