The LabVIEW For Loop is a structure that will execute code contained within a finite number of times. The number of times that the loop will execute is initially determined by the numeric value written to the "N" terminal of the loop, or by the size of an array wired as an input to the loop (when indexing is enabled for the input tunnel).
