Use Local Variables to read or write to one of the Controls or Indicators on the Front Panel of a VI.

Usage

Stopping both parallel loops using the same Stop Button.

It is necessary to change Stop Button Control mechanical action from Latch... to Switch...

Best practice

Using Local Variables breaks data flow execution. It is useful when it is not possible to pass data through wires, like parallel processes. In this case, the use of Local variables can be a solution. However, you should be careful when using this resource because it can generate unexpected behavior when you write values in multiple places in your code. A good rule to follow when you use Local Variable is: One Write, Multiple Reads.
