Issue Details

I have two controls in my front panel and I would like to be able to set them to the same value by modifying just one of them.

How can this be done?

Solution

  1. Select one control and Right click>>Create>>Property Node>>Value.
  2. Change this property node to write by Right Click>>Change to Write.
  3. Wire the output of another control to the input of the property node.
  4. The value of the first indicator should update when you change the second control.

Once you apply these steps, you will see a structure closely similar to the following image shown below:

 

Note: This image is a LabVIEW snippet, which includes LabVIEW code that you can reuse in your project. To use a snippet, right-click the image, save it to your computer, and drag the file onto your LabVIEW diagram.  

With this structure, you will be able to set the value of the first control updated by just modifying the second control. This solution also applies to additional controls by creating property nodes for them.

Additional Information

The involvement of Flat Sequence Structure in the image provided is to avoid the occurrence of a race condition when executing this snippet. It might not be needed in your application.
