Labview DAQmx start/stop - Do I need to reCreate Task?

[rmp]

Hi folks,

I'd like to be able to call DAQmx Timing while I'm collecting data. I know I can't call this while in a DAQmx read loop. But I can't figure out if I can DAQmx Stop Task, DAQmx Timing and DAQmx Start... or do I need to:

 - DAQmx stop, DAQmx Clear

 - DAQmx Create Task

 - DAQmx Timing

 - DAQmx Start Task

I think I'm getting myself confused in various states between these two modes, and getting errors. Anyone know which is correct?

The DAQmx Task state model describes the state machine of the Task,

https://www.ni.com/docs/en-US/bundle/ni-daqmx/page/taskstatemodel.html

In short, you don't need to clear/create task, once created, ensure that the task is not running when attempting to configure timing.
