AHA!

Do you select the resource from the dropdown list BEFORE the Loop starts?  A SR might help

Hi Jeff

I am facing the same problem. (i.e. Labview gives error when the Canonical Visa resource name is blank)  I am using the pickering switch through the GPIB. When I first run the intialize vi (pickering device's driver) I do not get Canonical name but its coming on Second time I do it.

I could not understand the solution in this discussion. Please explain me what is SR.

The solution was to simply select the resource from the drop down list before starting the VI.

Please see this snap shots, When I run my project Labview gives error (as I found that  Canonical Visa resource name is blank). But the same VI works fine, When  I put it in sepearate new vi and am getting the Canonical Visa resource properly.

Please help me

Hi

A correct visa resource is more than just a string. try to find the real visa resourcename in the IO palette

and there yoou should be able to select the correct resourcename from the frontpanel.

I see here something that looks more as a hack to get something like a visa resource.

We found the solution , that pickering switch labview driversw does not support dynamic calling .
