LabVIEW
I have a question about how to use property nodes.
As shown in the picture above, there are two ways to use the property.
Is there any difference between these two?
Such as speed or optimization or memory usage.
No difference in the way you are showing them. But you would get a lot more performance from using a Local Variable if all you are doing is setting the value.
The bottom one is linked to a control in the same VI. The top requires a reference so you can operate on the properties from within a subVI as long as the reference is wired to a connector (In that second case you cannot use local variables).
As has been mentioned, property nodes are most useful for properties other that the "value". Values belong in a wire.
