Hello again
Local variable is the exact copy of your control, but you can read and write to it regardless whether it is indicator or control.
Property node is a special way of setting and getting different properties like: label, position, size, etc. of your oryginal control or indicator.
There is also difference in memory management when using local variables and property node. The property node is generaly slower than local variables, but it gives you more possibility (object oriented programming).
