Trouble importing visa connection from ini file

[pbuerki]

Hello,

In the attached Test Import Connections.vi, I am trying to import a VISA resource name (COM3) from a configuration file. I import the keys into an initialized functional global. The functional global is then read and the output sent to an output cluster. However, after executing the code, I always end up with an empty string for the resource name in the output cluster. When I run the vi inside the main application, I get an Error 3, (Possible reason(s): LabVIEW:  Internal error. Wrong memory zone accessed. ========================= NI-488:  GPIB Controller not addressed correctly.) (I do not have a GPIB controller in my system.) 

Any ideas why this is not working?

Thanks for your help.

Peter

With each write, you are clearing all of your previous data in the shift registers.  You need to perform 1 write or do a check for each parameter to see if it is being updated.

Typical case of not seeing the forest despite all the trees... Thank you crossrulz. I attach the fixed vi.

With best regards,
