Boolean Indicator Value Change Count using LabVIEW

[ashley_gee]

Overview
This VI demonstrate how to implement a count of how many distinct time a Boolean Indicator reads True

 
Description
Here is a brief description of the example:

By using a Case Structure controlled by the current boolean value and a Shift Register to store the Boolean value of the previous iteration, we can keep an accurate count of how many times the LED indicator changes from F to T.  This solution does not use an Event Structure nor any Local Variables, and is not blocking.

Requirements

1. LabVIEW 2014 (or compatible)

Steps to Implement or Execute Code

1. Download Boolean LED Count.vi
2. Run the vi.
3. Click the Control.
4. The count will be displayed.
