Sequence Structure

Sequence Structure

Consists of one or more subdiagrams, or frames, that execute sequentially.

Use the Sequence Structure to ensure that a subdiagram executes before or after another subdiagram.

Dataflow for the Sequence Structure differs from dataflow for other structures. Frames in a 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.

Inputs/Outputs

Tunnel

Point through which data enters or exits a structure.

Tunnel Restrictions

You cannot drag tunnels across the frames of a Sequence Structure.

Avoid Overuse

Attempt to control the dataflow of your VI by establishing data dependency or using flow-through parameters.
