Error -200488 with DAQmx Start Task VI

  • NI-DAQmx

Issue Details

  • I have created an DAQmx task in NI-MAX. In NI-MAX this task works as expected. However, when I try to use this task in LabVIEW I get the Error -200488 at the DAQmx Start Task VI
  • After upgrading NI-DAQmx driver, the task in NI-MAX appears with Error -200488.
  • I moved my VI from an old computer and is not longer running in a new machine.


  1. The error might be caused by Unicode characters in the name of the task (i.e. ä,ü or ö). In order to solve this issue, rename the task in NI-MAX to remove all non-Unicode characters. The execution of the task should work now.  
  2. If the error persists, reinstall the INI file in NI-MAX (File> Import) or create the NI-MAX configuration again.
  3. In case you moved the VI to a new machine, this error could be caused because the VI is calling resources or tasks that were defined in the old machine. In this scenario, you'll need to import the MAX configuration file to the new machine following the steps in this article.
  4. If step 2 does not work, a reinstallation of the NI-DAQmx driver should fix this error.

Additional Information

LabVIEW only offers a limited support for Unicode characters and will interpret them following language options in Windows.
