Issue Details

When I try to execute my LabVIEW code that is controlling hardware or instruments, I get Error -1074130544. I am able to communicate with the instruments in NI MAX but the program still throws this error. How do I resolve this ?


In most cases, this error is caused by an uninitialized instrument or hardware component.
  • Ensure that the initialize VI for your device is called before any other functions are called.
  • Ensure that there is a VI called that closes the communications to the device using the close VI.
  • Ensue that multiple Initialize VI's have not been called for the same device.
  • Reset the MAX database on your computer if none of the above steps help you.
  • Make a new VI having only one initialize and once close VI wired to each other and run it. Check if the error still persists by wiring appropriate error indicator.
