What is the best way to connect quizix PumpWorks to labview?

PumpWorks share data using Dynamic Data Exchange (DDE),what is the best way? To use an OPC Server betwen labveiw and pumpworks or  DDE?

Hi.

If the instrumet can communicate with an OPC server I think both methods are fairly equal.

There is a chance that you might have to reinstall LabVIEW without OPC server if you choose DDE, as it is known that it might conflict with the DDE server.

The PumpWorks program can only use DDE communication linkl: http://www.vindum.com/Q%20PumpWorks%20Manual031306.pdf 

The question is: What is the best way to connect the program with labview, use DDE or use for example Kepware OPC Server that can communicate with both systems. 

Thank you for your answer!

If the program only handles DDE communication the best method will be via DDE, as LabVIEW handles this. Otherwise you will have to add another instance to the system(OPC Server) that will make it more complex, and causes more overhead.

See the previous link under "Using LabVIEW as a DDE Client".
