Topkapi Inside - Épisode 1 - Les serveurs de données de Topkapi

Introduction to Sharing Top Capi Data

Importance of Data Sharing

• Sharing data from Top Capi is essential for interoperability, allowing different entities like companies or applications to function effectively.

• It facilitates standardized exchanges between heterogeneous systems, enabling integration with tools such as GMAO, hypervision systems, and ERPs.

Methods for Data Sharing

• Top Capi can operate as an MBUS server for real-time data sharing; this method is simple to implement.

• The application can also act as a Modbus slave, supporting both serial and TCP/IP communication methods.

OPCUA Server Configuration

Advantages of OPCUA

• The OPCUA server allows not only real-time data dissemination but also historical data transmission while incorporating security features like certificate exchange and identity control.

• Configuration involves specifying the published address for connection and setting access rights based on user roles.

Architecture Considerations

• The OPCUA server can be installed on a separate machine from the supervision system, which is recommended by ARAL for inter-system data exchange.

Web Service Integration

Features of Web Service

• Top Capi includes a web service based on a REST API in JSON format, allowing external applications to communicate using open standards.

• This web service has built-in security layers (HTTPS and authentication), although it requires development skills for client implementation.

Database Connectivity

SQL Connector Usage

• Top Capi can interface with databases via an SQL connector, centralizing all processed data into an external database.

• While this solution simplifies configuration without requiring SQL knowledge, it does not provide real-time information and needs specific maintenance skills.

Flat File Export Options

Proprietary Format Conversion

• By default, Top Capi uses proprietary formats; however, utilities are available to convert these files into tab-delimited text files for easier use by external software.

• This conversion process requires specific settings in Top Capi and does not allow access to real-time application data.
