Dynamic Data Exchange (DDE)

DDE is the passage of data between applications, accomplished without user involvement or monitoring. In the Windows operating system environment, DDE is achieved through a set of message types, recommended procedures (protocols) for processing these message types, and some newly defined data types. By following the protocols, applications that were written independently of each other can pass data between themselves without involvement on the part of the user. For example, InTouch® HMI software and Microsoft Excel. See also topic, item, I/O Server, SuiteLink.
