one indicator for several different parts of multiple vi

[lvuser333]

I have multiple sub VI's that all go into one higher level VI. The sub VI's occur in a sequence and they all read the same voltage off a device. I want to have only one indicator on the upper level that shows the voltage in each sequence. I tried using global variables but it is not working, I think it might have something to do with the while loops. I have attached one of the subVI's

Thanks

Pass a reference to the main vi control to the subVI and use the value property node to update it.

You may want to consider using a state machine to implement your code. It can make updates to the same controls/indicators easier since your data would flow through the state machine. All of your updates can occur after the case structure for the state machine. In addition, a state machine will make it much easier to add new functionality.

I generally do not like passing references to items on the UI to processing subVIs. Doing so couples your processing code with the UI code and makes reuse more difficult. If I do pass references it is to subVIs specifically used for the user interface.
