When loading a DAQmx task in LabVIEW, the task loads through a series of states
. The Start Task
, Stop Task
and Control Task
VIs transition the task through these states. These states, and the transitions between them are as follows:
If the Start Task VI is called without any preceding Control Task VIs, then within the execution, it must transition the task from the Unverified state through each of the intermediate states through to the Running state. In larger tasks, reserving system resources
and committing settings for these resources
can take a long time, slowing the execution of the Start Task VI.
Alternatively, the Control Task VI can be used to transition the task to the Verified, Reserved or Committed states. Separating these steps from starting the task will reduce the execution time of the Start Task VI, which is especially valuable if the task is being started multiple times, or if starting the task is time sensitive.
