Error message

[Alias007]

Hello,

I am getting this error message:

Possible reason(s):

LabVIEW:  File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Mac OS, and / on Linux. Verify that the path is correct using the command prompt or file explorer.
=========================
NI-488:  Nonexistent GPIB interface.

Can somebody explain this error and how do I solve it.

Thanks.

And this happens when? Provide some details and perhaps we can be of some help...

The error occurs both in write & read function. I am using the one of the example (GPIB.vi) provided by NI.

[smercurio_fc]

Have you confirmed that the GPIB board has been properly installed and is recognized by the operating system? Can you see the board in MAX (Measurement & Automation Explorer)? Run MAX and then expand the "My System -> Devices and Interfaces" tree. Is the GPIB board there?

[Alias007]

I see the instruments in the MAX. I can read the address using VISA read but GPIB read and write is giving problem (all my instruments).

[Dennis_Knutson]

Can you post an image of MAX showing the results of the instrument scan and an image of the front panel of the VI showing the address you are using?

[Alias007]

Here are the images.

It looks like your GPIB controller is installed as GPIB1 and the default is GPIB0. If you don't want to change it to 0, prefix the address with the controller number (i.e. 1:19). If you look at the VISA Resource Names (you don't have that list expanded), you would see GPIB1::19::INSTR.

[Alias007]

So change the GPIB Interface ID to GPIB0 and other thing VISA resource name I did not get it.

Did not get what?
