Which Conditions Require the Server to Run in Interactive Mode?

Last Update: 11/7/2018

This server can run interactively on the desktop or in the background as a service. Some of the conditions that require the server to run in Interactive Mode are as follows:

  • When serving data to a Dynamic Data Exchange (DDE) client (such as Microsoft Excel or Wonderware InTouch via the FastDDE interface)
  • When using the DDE Client driver to connect the server to a DDE application (such as when connecting to Microsoft Excel and reading data from a cell in a specific page of a spreadsheet)
  • When using the Wonderware InTouch Client driver to connect directly to the Wonderware Tag Database to read and write data
