Sequence

Controls the execution of a project by alternately executing and pausing steps. The Sequence step can pause the execution of steps in a project without stopping the execution of the entire project. For example, you can use the Sequence step to pause the execution of a step that acquires a signal from a hardware device so that another step in the project can use the same hardware device.

If you select Run preceding steps before following steps, the Sequence step allows steps that precede the Sequence step to execute once, then pauses the execution of those steps and allows the steps that follow the Sequence step to execute once, and so on.

If you select Start a sequence or End a sequence, the Sequence step becomes the beginning or end of a sequence and does not affect the execution of any steps that appear before or after the sequence in the Project View. Use the Start a sequence and End a sequence options when you want to allow steps outside of the sequence to run continuously, such as if you want to generate a signal continuously.

Note  When you use the Sequence step to reuse hardware, you cannot perform a continuous signal acquisition because LabVIEW SignalExpress stops and starts the hardware device.
