Do you initialize the feedbach node?. If not initialized, the feedback node keeps its last value on subsequent executions of the vi.
Make sure that you close the file reference using "Close File" before leaving the main vi.
Do you have a continuous acquisition configured in DAQ Assistant?If so, have you tried stopping the acquisition throught stop input terminal?
Lastly, try creating the associated code with the DAQ Assistant. This will help you troubleshooting the issue. To do this, select "Generate NI-DAQmx Code" from the shortcut menu.
It should be helpful if you could attach a simple example that shows this behaviour.
