How to make an LED have a lable when it is ON and a different labe when it blinks?

[LT42]

Hi,

I have a very simple code using the feedback node to make a LED stay off when both of the push buttons are off; otherwise, the LED starts blinking.  I need like for the LED to show "NO ERROR"  label when it is not blinking, and to show "ERROR" label when it starts blinking. But I have not been able to figure out how to do this without having two different LEDs.

Thanks,

Your description is very confusing.

• What is the significance of the feedback node? A feedback node does typically not decide if a LED is on or off.
• What is the significance of two LEDs? Do they depend on each or are you looking ar a solution for a single LED that then can be duplicated?
• Are there two (Off, blinking) or three states (off, blinking, on)  needed for the LED?
• Are you talking about the blinking property or are you talking about blinking=on,off, on, off... etc in succession.

You can programmatically change the caption or boolean text. You could also use a cluster of a LED and a string indicator for more flexiility. Please show us your code so we can better understand what you need.

Blinking = attention-getter   - got it.  However, if there is no error, I would not use any caption/label, or rather I would make the caption/label invisible (with a property node), and then make it visible again when there is an error. 

Also, just making the ON text read "ERROR" should work too, unless you use steady on for something else.

The attached example shows how you can use property nodes to change the boolean text (as mentioned above) and the blinking property. 

Is this the functionality you were looking for?

Peter D,

I think that is the functionality that I am looking for. The only problem is that I have LabView 9, and the file is in a newer version. Would it be possible for you to uploade it in a different version?

Thanks.

Hi LT42

Here it is in LabVIEW 9.0.

Thank you very much. That was very helpful!
