Outline of block diagram blinking red

Solved!
Go to solution

Hello. I don't have access to the Vi in question, at this time so I will make this as general as possible. My Vi has been running correctly for a week or so but today it has started blinking red around the border of the Block Diagram. When the Vi finishes it makes the entire block diagram black for a moment, followed by this red square around it. What does this red box mean? They are still able to run the Vi, that's why I can't interupt them however, there isn't an alarm showing or anything. I have tried watching as they run but am getting no where fast. I am not asking to pinpoint the problem, just wanting to know what the blinking red box means. Thank you

Probably somebody added and forgot a breakpoint.

It means that your diagram has been set at one big "breakpoint". Go to View >> Breakpoint Manager and clear the offending breakpoint.

 

If you hold CTRL while a VI is running, LabVIEW adds a breakpoint to everything you click, so just be careful with that. I've accidentally added breakpoints to my code many a time.

Cheers

Thank you, that was it. I forgot to enable the password so the block diagram can't even be accessed. Of course no one did anything, it happened magically. Smiley LOL
