To create a FGV to pass Reference.

[stark8]

Hi....

Can anyone help me to create a FGV to pass reference for the BK precision 9200 Instrument drivers VI's. I didn't understand how to create a reference for those specified VI's.

Thankyou.

Simple way is to create Single Run VI with different State and Enum Defining the States.

Use Shift Register to hold the reference Session.

For what reason do you need a FGV?  What is wrong with just passing the reference around on a wire?

IMHO: Functional Global Variables and "Action Engines" are a thing of the past.

They were workarounds that were useful at the time but I can't say I have needed one in a decade or longer.

The FGV was a workaround before the Global Variable was created.  That is why they are still occasionally called LabVIEW 2 Globals.  I would put Action Engines as an expansion of FGVs by creating explicit things that can be done with the global data.  They still have their place, but I also find myself using less and less Action Engines purely due to its singleton nature.
