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 motivation

Performance “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 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
