C# API to access Shared Variables?

[LaneFox]

Hi,

Sorry if this is the wrong forum, not sure where to post these types of questions.

I'm new to NI products and building some middleware to communicate between applications. Veristand Server is running and hosting Shared Variables used for a simulation and I would like to tap into these in a C# application.

I can't find any API to do this, as the .NET examples seem to offer access to the Controller, models and parameters. Is there any API to read/write shared variables?

Thanks,

Lane

Thanks, some good ideas in there. We're currently talking over sockets but looking into accessing the data directly. I don't think dumping out to a file is feasible in our architecture.

The shared variables can be accessed through a restful interface. So basic TCP\IP... Problem is finding the documentation.

Some documentation is in the LabVIEW Help. Search "Getting Variable Updates" (online LV Help).

An HTTP GET on this address used to work for me:

http://localhost:3580/nivariable/VariableValues('ni.var.psp://localhost/EtherCAT%20Master/Mod3/DI1')/Value

Maybe this will help a bit (not sure):
