How does one configure LV to communicate with a VStudio app in real time?

[Mark@IntentDriven]

I need something like an OPC server in LV8. The objective is to perform signal processing (scaling, filtering, etc.) in LV but then transfer the data stream in real time to VStudio. VStudio will then be responsible for display, control, and storage of the data. It seems that an OPC server is the way to go, but it does not appear that you cant make an OPC server in LV8.

I would think OPC to be total overkill for this. Also there are a few very strange things in this request too. One of LabVIEWs very strong points is actually the data presentation capabilities. Why you would want to do that in Visual Studio instead is beyond my grasp.

But if you really want to do what you say you want to do, what I would do is actually either have the LabVIEW code be built into a DLL with the application builder and call it as DLL from your Visual Studio app (this is certainly the fastest and most performant way) or device a TCP/IP protocol myself both in LabVIEW and your Visual Studio app to share data between the two (this would be my choice if the LabVIEW part and your Visual Studio part would need to reside on different host computers).

OPC will only add lots of costs (you would need a licensed external OPC server like our CIT Engineering OPC Server) and complexity to this which is not really necessary.
