Passing VI handle

[VI_Joe]

How do you pass a VI handle (reference number) from one TestStand step to another?

Thanks in advance.

Basically in your step (i.e.intialize) you would take the output handle and create a teststand local variable of LabVIEWIO control type. Click on the expression browser button when you are configuring your step module output. Also see here .

I would instead use a local variable of type 'Number' not a LabVIEW IO Control type:

When I mapped a VI that outputs a VI Reference, TestStand automatically gave it a type of Number ( U32 ). 

See attached picture.

It depends on your usage of the handle, it actually may be beneficial to save the Reference in a FileGlobal if you intend to use it within multiple sequences.

Thanks,
