How to detect if RTEXE is running on PXIe-8133 RT Controller

[mavlc]

Hello,

i need to know from my PC if some RT executable is running on remote RT machine (PXIe-8133).
Is there any way how to detect in LabVIEW if some application is running on Real-time and possibly which one?

Thanks a lot.

If the executable is created with LV, you could try to connect to it using VI Server.

Hello Mike,

thanks for a reply. Yes, rtexe was built in LV2013.

How can I programmatically do it?

I tried to use Open Application Reference and then Open VI Reference, where i placed rtexe path instead of vi path, however I got error 1059: Unexpected file type.
Which function should I use to connect rtexe using VI Server?

Thank You very much.

If you use the open VI reference, you have to specify the name of a VI that is currently loaded in the running instance you referenced - like "main.vi" or something like that.

Thank You very much for your help.

I think that i know what You mean but it isnt still working properly.

I got this path by calling Current VI's Path in built RTEXE on RT target.

I looks like "c:\RT EXE Folder\Main.rtexe\Main.vi".

However when I tried to connect to this using first Open Application Reference with machine IP and port number = 3363 and then Open VI Reference with just created application reference and the vi path above, I am still getting Error 7: File not found.

I think that there has to be something wrong with this vi path because when I tried the same approach on RT target (without Open Application Reference) I got the same error 7.

But the path I just copy from Network Shared Variable therefore any typo is impropable.

Do I miss something?

Thank You very much.

The big point is that calling a remote VI in this way, you are assuming that the VI is already in memory. In that case you don't have to give a complete path, just the name of the VI.

Yes, it works!!! Thank you very much.
