NXG: Sample code to write to shared variable

[ElioTx]

I have searched builtin help and online but can't find an examle how to write a shared variable (SVE) in LabView NXG 5.0. I would really appreciate if someone can provide a pointer how to do it. I know how to do it in LabView but not NXG.

You've seen this help topic, then?  You should probably be using tags, anyway.  At least according to the help file.

Yes, I have re-read that so many times but I couldn't figure out how to use it. I was hoping to see an example.

It's pretty straightforward.  But then again, I have used NXG long enough to anticipate what they are trying to do, so maybe that's why it seems straightforward to me.  What is it that you are having trouble with?

I am not able to write to shared variable. I am translating what I have been doing using LabVIEW (the old one). 

For example, in the LabView you create a project library to hold the shared variable. I don't know how to do this in NXG. 

This is what I have tried so far, not working. Note I am using PSP Variable - I am not sure if I should use PSP Variable Engine. I am totally lost here.

I am using the link below as my reference for using Shared Variable Engine

You might try adding ni.var.psp: in front of the URL. I did a quick test with the snippet below and it works as expected.

I did have to create the shared variable and process manually using Distributed System Manager. I don't think NXG offers a way to create and deploy shared variables directly.

Thanks @MichaelBlazer! It worked.

Note: For some reason it was not working initially. After I deleted the variable in NI Distributed Manager and then re-created the same variable name, it worked.
