Link a message to Boolean state of an LED

[mehrdad6687]

Hi,

I am a new user to LabView and I am preparing an HMI for an electrical power system which contains breakers. I can control breakers in the system with the LabView VI I have made and can toggle their states. The states are reflected with a boolean square LED so the breakers can be ON or OFF! It seems fine now but I would like to do something more complicated. I would like to link a message, like a warning to the OFF state of the LED. So, if a user turns the breaker to OFF, I want a warning to appear with a string which says: "Breaker #.. is open!".

Is this possible to do in LabView. How can I link the LED state to a string? Any help is appreciated. Thanks!

• Yes, it's possible.
• Use a case structure (or even better a Select node) to "link" the LED/button/switch to your string indicator…

As a "new user to LabVIEW" you really should take those Training resources as offered at the top of the LabVIEW board!
