In some situations the default LabVIEW data types have limitations in that they do not support a NULL data type. For instance the boolean control have 2 states on/off. But there might be a third state (i.e. not assigned / NULL).
By using an XControl and the Execution State event the attached code demonstrate a boolean LED that when executed but not assigned is yellow. After the first data value is assigned the LED will either be green or red depending on that value being true or false.
After this the boolean will execute as a normal boolean control, until the program is stopped and LabVIEW goes back to edit mode.
Examples:
Program when first started (no value assigned):
Program when boolean is set as true and false.
Program after finished execution (goes back to unassigned state):
Edit: Updated the code to fix dependency conflict.
Hi Anders Rohde, Thank you.
Here, In my application I am evaluating data with some limits from the can message.
Based on the evaluation it giving result Pass with Green and Fail with Red color.
But by default it is showing Fail with Red color before running application.
My intention is result should be in "Not tested" mode with some other color.
Could you please suggest how to do it?
