1 GENERAL PRODUCT INFORMATION
1.1 I
NTRODUCTION
This manual will explain the operation of the software tool FlowDDE. It has been written based on FlowDDE V4.67, but
should be suited for former (and future) versions as well, although functionality may differ from what is described.
FlowDDE is a Dynamic Data Exchange (DDE) server, an easy connection between Windows applications and digital

instruments. DDE provides a basic level of interprocess communication between Windows applications.
By using DDE commands, sent by software to FlowDDE, data can be sent to or requested from digital instruments.
FlowDDE handles all communication to the instruments and provides the data to applications.
Examples of applications with DDE communication are Microsoft Excel and LabVIEW (National Instruments). Several
Bronkhorst applications require FlowDDE for communication to the instrument(s), e.g. FlowPlot and FlowView.
