A Structure is a construct that surrounds other programming elements. It divides the block diagram into a hierarchy of sub-diagrams. Some structures only contain one sub-diagram, or frame, (i.e. For Loops, While Loops, In Place Element Structures, etc.). While others contain multiple sub-diagrams, or frames, (i.e. Case Structures, Event Structures, Diagram Disable Structures, and Conditional Disable Structures).

Structures have three uses. They either:

  1. Control the execution between blocks of code ([Flat Sequence structure|Flat Sequence Structure]], Stacked Sequence Structure, In Place Element Structures, Timed Sequence)
  2. Allow a choice between different blocks of code to execute (Case Structures, Event Structures, Diagram Disable Structures, Conditional Disable Structures)
  3. Allow code to repeat execution (For Loops, While Loops, Timed Loops)

LabVIEW 2017 In LabVIEW 2017 the Type Specialization Structure was added in conjunction with the addition of Malleable VIs.
LabVIEW 2014 In LabVIEW 2014 the Stacked Sequence Structure is considered to be deprecated and has been removed from the Structures Palette although it is still functional to code upgraded from older versions.
LabVIEW 8.5 In LabVIEW 8.5 the In Place Element Structure was added.
LabVIEW 8 In LabVIEW 8 theDiagram Disable Structure, Conditional Disable Structure and Shared Variable were added.
LabVIEW 7 In LabVIEW 7 Express the Flat Sequence Structure and Feedback Node were added.
LabVIEW 6 In LabVIEW 6i the Event Structure was added.
