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.
