DDE/FastDDE communication protocols allow communication between a client and a server. DDE protocol is developed by Microsoft whereas FastDDE protocol is proprietary to Wonderware.

Important! On Windows Vista and later operating systems, Local DDE is supported only when the DAServer is configured as "Not a Service" and activated from its executable file or launched from InTouch. Local DDE is not supported when the DAServer is activated from the System Management Console (SMC).
