Exchange Data with Other Applications

You can transfer data between Plant SCADA and other software for storage, analysis, and post processing, or to control and tune your Plant SCADA system.

Plant SCADA uses the following methods to exchange data:

• Use DDE (Dynamic Data Exchange) (DDE), where Plant SCADA can act as a:

  • DDE server providing tag values to requesting clients

  • DDE client to request data from other applications.

• Use ODBC Drivers (ODBC), where Plant SCADA functions as an ODBC server, allowing other applications to read Plant SCADA variables directly.

• By using a common external database, where Plant SCADA and other applications use the same database to store and share information.

Plant SCADA also supports importing and linking variable tag data from external databases (see Link Tags to an External Data Source).
