How do I get a property value from my PreUUTLoop callback into my MainSequence?

[tman]

I am trying to get a propety value (it's a VISA session number) from my PreUUTLoop callback into my MainSequence so that I can then contol my piece og GPIB equipment. How do I do that? Do I use a parameter or local variable, or something else? What mechanism do I use to pass it?
Thanks

Hi,

You will need to write it to a variable in the FileGlobals, that way it will be accessible to both sequences.

As Ray Mentioned using Sequence File Globals would be the easiest method. But if you trying to stay away from Globals, you can directly pass the value from a local variable in the PreUUT callback sequence to a local variable in the MainSequence by using a Post Expression in one of your steps in the callback sequence.

RunState.SequenceFile.Data.Seq["MainSequence"].Locals.VAR = Locals.PreUUT_VAR

Hope this helps
