Access DataSocket Server from MATLAB / C program

[rasmus@slac.stanford.edu]

I would like to read (and eventually write) data from a DataSocket Server using MATLAB.
Currently, I am just using low-level UDP commands to send data from LabVIEW to MATLAB, which works but is somewhat cumbersome and prone to programming errors. Using NI's DataSocket appears to be a much more elegant solution.
Has anybody written code to connect to DataSocket servers using MATLAB, C or C++? Is the DataSocket protocol specified somewhere?

You will find some examples in the LabVIEW example finder that I think will help you.  You can go to Help >> Find Examples... and search for DS Write.vi to find this file.  There are other examples if you search DataSocket.

Dear Brian,

thank you for your help. I have succeeded in posting data to a DataSocket server from LabVIEW, and I can read it from another LabVIEW program. Now, I would like to access this data from other programs than LabView. Is there some C / C++ / MATLAB example code on how to do this?

Thank you

Rasmus

Have you look at measurement studio ? I think they expose access to read Datasocket or variable from c side.

The following article shows how to do this in Measurement Studio.  [link removed; article no longer available]
Thanks!
