Use the Execution Control Express VIs and structures to add control and timing to VIs.

Examples

Refer to the following example files included with LabVIEW.

While Loop with Button
Repeats the subdiagram inside it until the conditional terminal, an input terminal, receives a particular Boolean value. When you place this While Loop on the block diagram, a stop button also appears on the block diagram and is wired to the conditional terminal.
Flat Sequence Structure
Consists of one or more subdiagrams, or frames, that execute sequentially. Use the Flat Sequence structure to ensure that a subdiagram executes before or after another subdiagram. Data flow for the Flat Sequence structure differs from data flow for other structures. Frames in a Flat Sequence structure execute from left to right and when all data values wired to a frame are available. The data leaves each frame as the frame finishes executing. This means the input of one frame can depend on the output of another frame.
Case Structure
Contains one or more subdiagrams, or cases, exactly one of which executes when the structure executes. The value wired to the case selector determines which case to execute.
Time Delay
Inserts a time delay into the calling VI.
Elapsed Time
Indicates the amount of time that has elapsed since the specified start time.
