Controlling a push button switch?

[Juan 387]

Excuse my ignorance. One weekend playing with LabVIEW...

Situation: A transmitter controller has two switches:
1) RF output (ON/OFF)
2) Output switch (Antenna-1/Antenna-2)

Rule: When the output power is ON you cannot change the state of the output switch since it might damage the transmitter when the load changes.

Question: How can I freeze the position of the Output Switch when the RF Power switch is in the ON state?

Here's one way using LabVIEW 6 references.

Why bother with a reference when an attribute node can do it in less space
and effort?

True, but references can be used in sub-VIs. Attribute nodes can't.
