STRUCTURES IN LABVIEW
INTRODUCTION
STRUCTURES are graphical representations of the loops and case statements of text-based programming languages. There are cases when a decision must be made in a program. In text-based programs, this can be accomplished with statements like if-else, case
and so on. LABVIEW includes many different ways of making decisions. The simplest of these methods is the select function located in the functions palette. This function selects between two values dependent on a Boolean input.
Use structures on the BLOCK DIAGRAM to repeat blocks of code and to execute code conditionally or in a specific order. Like other nodes, structures have terminals that connect them to other block diagram nodes, execute automatically when input data are
available, and supply data to output wires when execution is complete. Each structure has a distinctive, resizable border to enclose the 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. The terminals that feed data into and out of structures are called tunnels. A tunnel is a connection point on a structure border.
