Boolean Array Case Selector in LabVIEW

[Nate.H]

Overview

This example gives an efficient way to handle all possible combinations of multiple boolean input values.

Description

This VI demonstrates one way to organize your logic for determining which case of a case structure to execute. It becomes very useful when you have to handle every possible combination of multiple boolean values. The number of possibilities is 2^n, so with 4 boolean values there are 16 possible combinations of those values.

Requirements

LabVIEW Full Development System 2012 or compatible

Steps to Implement or Execute Code

1. Run the VI
2. Click on the Input Array control to change the binary values and selected case Messages

Additional Information or References

Note that the functionality of the case structure makes it possible to handle multiple possibilities with one case very easily. See the LabVIEW help for the case structure for the syntax for having a case handle both close and open ended ranges and lists of values.
