Use timed structures on the block diagram to repeat blocks of code and to execute code in a specific order with time bounds and delays.
Each timed structure has a distinctive, resizable border to enclose a section of the block diagram that executes according to the rules of the structure. The section of the block diagram inside the structure border is called a subdiagram. A timed structure has Input and Output nodes that feed data into and out of the structure to provide configuration data and return error and timing information. Timed structures can also have terminals on the structure border that feed data into and out of the structure subdiagrams.
Use the following structures located on the Timed Structures and VIs palette to control how a block diagram executes with time bounds and delays:
