The following sections are the palette and tools of the LabVIEW

software that are used for the sender and the receiver programs [ 83 ]:

A 4. 1 Wiring a VI Block Diagram:

A 4. 2 While Loop

Repeats the subdiagram inside it until the conditional terminal,

an input terminal, receives a particular Boolean value. The Boolean value

depends on the continuation behavior of the While Loop. Right-click the

conditional terminal and select Stop if True or Continue if True from the

shortcut menu. You also can wire an error cluster to the conditional

terminal, right-click the terminal, and select Stop on Error or Continue

while Error from the shortcut menu. The While Loop always executes at

least once. The iteration (i) terminal provides the current loop iteration

count, which is zero for the first iteration.
