Pourquoi OLE for Process Control (1) ?
Ouverture Permet de dialoguer avec des équipements multi-fournisseurs Les données acquises au niveau Terrain sont automatiquement disponibles pour les niveaux supérieurs (gestion et contrôle) de l’usine Données accessibles aux outils MS-Office sous Windows Facilité d’utilisation Même interface utilisateur pour tous les composants

Pourquoi OLE for Process Control (2) ?
Performances Interface développée avec Microsoft C++ Performances pratiquement identiques avec celles des interfaces de base de SIMATIC NET Echange d’importants volumes de données Communication du type Client-Server Connexion Accès aux données à partir de tout PC sur le réseau LAN/WAN (via COM/DCOM)

OPC : Comment ça marche? OPC Client Démarre la liaison OPC
Demandes de lecture/Ecriture OPC Echanges basées sur COM/DCOM Données: uniques ou par groupes OPC Server Exécute les requêtes du client Gestion des rafraîchissements cycliques Mise à jour des données internes OPC Client OPC OPC Server

OPC motivation Performance Accessibility
“Custom Interface” for high-performance C/C++ applications (practically same performance as the SIMATIC NET basic interfaces for in-process servers for DP) “Automation Interface” for easy-to-generate VB applications Efficient data exchange between a process device and an application by means of: synchronous and asynchronous reading and writing of variables observation of variables by the OPC-server with message to the client in the event of change use of quantity operations Accessibility Accessible from any computer in the LAN (via COM/DCOM)

OPC offers standardized interfaces (APIs) for access to process data
OPC aims, advantages Applications are independent of the communication systems of one manufacturer Adaptation to protocol- and vendor-specific interfaces no longer necessary Reuse of existing and new developments and the safeguarding of investments Programmable controllers can be connected to a host of applications Communication access by office applications such as Microsoft Excel or Access to the automation level and its devices OPC offers standardized interfaces (APIs) for access to process data
