8.6 Dynamic data exchange

Dynamic data exchange (DDE) is a standard Windows 3.1™ mechanism
for sharing information between different windows applications. The LSGUI
uses DDE to make measurement data available to other windows programs
as it is being reported by the L-Series unit. No specific action is required by
the user to enable DDE as it is always active. The LSGUI acts as a DDE
server making data available for other programs to use. To use DDE data in
other windows applications, the application, topic and item names need to be
known. The following names should be used to access DDE data from the
LSGUI program:
Application Name
Topic Name
Item Names
Example : Excel spreadsheet
To obtain the voltage measurement value for phase A in an Excel
spreadsheet cell, enter the following formula : "=lsgui|measurement!ampa"
Use the appropriate item name to access other parameters.
