Using DDE
DDE (Dynamic Data Exchange) is a mechanism within Windows that enables data to be exchanged between two different programs, such as VTScada and Microsoft Excel. The program that supplies the data is called the server, while the program that accepts the data is referred to as the client. VTScada can act as either a client or a server.
DDE can also enable VTScada to accept data from another application, such as a chart, word processing document or spreadsheet. To do so, VTScada uses its DDE Client tag.
The application that supplies the data is called the server, while the program that accepts the data is called the client. VTScada can act as either a DDE client or a DDE server. The sections that follow provide instructions for configuring dynamic data exchange from an outside application to VTScada, and from VTScada to an outside application.
DDE is an older technology and may not be fully supported by modern operating systems or by newer features of VTScada.
