Error -200089 Using DAQmx Create Task

Issue Details

• Why can I run my DAQmx code only once? When running it a second time, I receive error

Error -200089  occurred at DAQmx Create Task
Task name specified conflicts with the existing task name.

• The first time I run my DAQmx code it works fine, but every subsequent time it errors out?
• Why do I get Error -200089 from the DAQmx Create Task VI?

Solution

When using the DAQmx Create Task VI in LabVIEW, you can save the task in Measurement & Automation Explorer (MAX) for future use by entering a task name in the New Task Name terminal. This prevents any future attempt to run the program because of a duplicate resource name for the task.

There are four options to resolve this issue:

• Leave the New Task Name terminal floating with no value. Your program will not save the task.
• Use the DAQmx Delete Saved Task VI  at the end of your code in conjunction with the DAQmx Clear Task VI or DAQmx Stop Task VI.
• Delete the task in MAX every time before you run the code.
• Manually handle the error, using the case of this error to instead start the existing task, maintaining functionality.
