cRIO modbus

Thanks for the code. I have added a read variable2 instruction to the host vi and when I run the vi's LabVIEW gives error "-1950679023 The connection to the server was disconnected". Why I get this error message?

MuratG:

Thank you for getting back with me. Are you able to still ping your cRIO while you are getting the error. I wonder about whether or not it is merely a network connection. You can also try to use Datasocket while you are experiencing errors to see if the issue is related to the Shared Variable Engine. Let me know what you find.

Thanks,

Rudi N.

Hi Rudi,

I discovered your message about cRIO modbus. I tried your project in the attached file and I am able to run RTVI.vi on the controller 9014 with Labview 8.5 and the SVvi.vi on a laptop. But when I built RTVI.vi to obtain a RT stand alone application with autorun, then I am not able to run the SVvi.vi on the Host PC. I receive a following Deployment Error.
How could I solve this conflict?

Regards, Nicolas

Hi Nicolas,

It sounds like the host VI SVvi.vi is attempting to redeploy Lib.lvlib, the library containing Variable1 and Variable2.  Since the variables have been deployed by RTvi.vi, they do not need to be deployed again by the host VI.  If you right-click Lib.lvlib and uncheck Autodeploy Variables, the variables will only deploy once. 

Another option is to create new variables in SVLibrary.lvlib and bind them to Variable1 and Variable2.  Both methods are discussed in more detail here.

Hi Jennifer,

It works perfectly well now, it was indeed the issue of Autodeploy Variables.
Thanks a lot!
