I/O Error Using a Third Party Instrument in LabVIEW



Primary Software: LabVIEW Development Systems>>LabVIEW Base Development System
Primary Software Version: 7.1
Primary Software Fixed Version: 7.1
Secondary Software: N/A

Problem:
I get an error -1073807298 when I try to run any of the VIs that come with the Instrument Driver for my Third Party Instrument. When I try to run a VI in the driver, I get the driver error "Could not perform operation because of I/O error" (Error # -1073807298) in the "error cluster out" on the front panel. I have the folder containing the drivers located at C:\Program Files\National Instruments\LabVIEW XX\instr.lib location and hence I see the instrument's VIs in my functions palette under All Functions>>Instrument I/O>>Instrument Drivers. What is causing this and how can I fix it?

Solution:
In some cases, some of the subVIs in this program have broken Run arrows. This was because various Call Library Function Node blocks in these subVIs were trying to look for the dll in C:\Program Files\National Instruments\LabVIEW XX\LabWindows XX\Released XXX\ folder. However, as mentioned above the dll should be and was in C:\Program Files\National Instruments\LabVIEW XX\instr.lib\ folder.

Two things can be done here. You can either point each of the Call Library Function Node in various subVIs to look for the dll where it is located presently, or you can copy and paste the dll in C:\Program Files\National Instruments\LabVIEW XX\LabWindows XX\Released XXX\ folder. Following the second option removed all of the broken arrows in this case and also the error.

This error number can also arise when using a VISA Read/Write, and details on that particular case can be found in KnowledgeBase 3O7F9LZ: Error -1073807298 Occurs after a VISA Read/Write
