Error -200488 with DAQmx Start Task VI

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.


  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. 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.
