Annotation of standard text IEC 61499-1-ed.2.0 :
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 definit une architecture generique et presente des lignes directrices pour lutilisation de blocs fonctionnels dans des systemes de mesure et de commande dans les processus industriels distribues (IPMCS). Cette architecture est presentee en termes de modeles de reference pouvant etre mis en oeuvre, de syntaxe textuelle et de representations graphiques. Les modeles donnes dans la presente norme sont censes etre generiques, independants vis-a-vis de tout domaine et extensibles a la definition et a lutilisation de blocs fonctionnels dans dautres normes ou pour des applications particulieres ou des domaines dapplication particuliers. Lintention est de faire en sorte que les specifications ecrites selon les regles donnees dans la presente norme soient concises, realisables, completes, non ambigues et coherentes. Cette deuxieme edition annule et remplace la premiere edition parue en 2005 et constitue une revision technique. Cette edition inclut des modifications techniques majeures liees aux: terme controle dexecution, variables temporaires, sequences de service, syntaxe pour le mapping des instances FB, syntaxe relative a la definition des types de segment, commandes de gestion READ/WRITE.
