Representation of process control engineering - Request in P&I diagrams and data exchange between P&ID tools and PCE-CAE tools (IEC 62424:2016)

This International Standard specifies how process control engineering requests are
represented in a P&ID for automatic transferring data between P&ID and PCE tool and to
avoid misinterpretation of graphical P&ID symbols for PCE.
It also defines the exchange of process control engineering request relevant data between a
process control engineering tool and a P&ID tool by means of a data transfer language (called
CAEX). These provisions apply to the export/import applications of such tools.
The representation of the PCE functionality in P&IDs will be defined by a minimum number of
rules to clearly indicate their category and processing function, independent from the
technique of realization (see Clause 6). The definition of graphical symbols for process
equipment (e.g. vessels, valves, columns, etc.), their implementation and rules for the
reference designation system are not in the scope of this standard. These rules are
independent from this standard.
Clause 7 specifies the data flow between the different tools and the data model CAEX.

Représentation de l'ingénierie de commande de processus - Demandes sous forme de diagrammes P&I et échange de données entre outils P&ID et outils PCE-CAE (IEC 62424:2016)

L'IEC 62424:2016 spécifie la méthode de représentation des demandes d'ingénierie de commande de processus dans un diagramme P&I en vue d'un transfert automatique de données entre les outils P&ID et PCE, et de manière à prévenir toute interprétation erronée des symboles P&ID graphiques pour une application PCE. Elle définit également l'échange de données de type demandes d'ingénierie de commande de processus entre un outil d'ingénierie de commande de processus et un outil P&ID au moyen d'un langage de transfert de données (appelé CAEX). Ces dispositions s'appliquent aux fonctions exportation/importation de ces outils. Cette deuxième édition annule et remplace la première édition parue en 2008. Cette édition constitue une révision technique. Elle est une extension compatible de la première édition. Les principales modifications et extensions sont décrites à l'Annexe E et résumées ci-dessous: - mise à jour et ajout de définitions; - remplacement du terme "identification" par "désignation de référence"; - mise à jour des catégories PCE et des fonctions de traitement; - version CAEX 3.0, introduisant les éléments suivants: rôles multiples natifs; - interfaces imbriquées; - informations supplémentaires sur le cycle de vie; - bibliothèque Attribute séparée; - exemples mis à jour; - mise à jour du modèle de données électroniques de la demande PCE: nouvelle bibliothèque d'attributs normative pour les attributs de demande PCE de base; - nouvelle bibliothèque d'attributs étendue informative pour les autres attributs de demande PCE; - nouveau modèle de données électroniques informatif de la demande PCE.

Predstavitev tehnike nadzora procesov - Zahteve pri diagramih P&I in za izmenjavo podatkov med orodji P&ID ter PCE-CAE (IEC 62424:2016)

Ta mednarodni standard določa, kako so zahteve za nadzor procesov predstavljene v diagramih P&ID za avtomatski prenos podatkov med orodji P&ID in PCE ter za preprečevanje napačnih razlag grafičnih simbolov P&ID s strani orodij PCE.
Določa tudi izmenjavo pomembnih podatkov zahtev za nadzor procesov med orodjem za nadzor procesov in orodjem P&ID na podlagi jezika za prenos podatkov (CAEX). Te določbe se uporabljajo za funkcije izvoza in uvoza podatkov teh orodij.
Predstavitev funkcij PCE v orodjih P&ID bo določena z minimalnim številom pravil, da bosta kategorija in funkcija obdelave teh orodij jasno opredeljeni ter da bo njuna opredelitev neodvisna od tehnik, uporabljenih za njuno realizacijo (glej točko 6). Opredelitev grafičnih simbolov za procesno opremo (npr. posod, ventilov, stolpcev itd.), njihova uvedba in pravila referenčnega sistema za določanje teh simbolov ne spadajo na področje uporabe tega standarda. Ta pravila so neodvisna od tega standarda.
Točka 7 določa pretok podatkov med različnimi orodji in podatkovni model CAEX.
