Listen only GPIB Labview

I have an application where I need to listen only on the GPIB bus (NOT be a controller or interfere in any way with the controller).  Then, when I see the information come across that I'm looking for, I need to use that to trigger another portion of my LabVIEW code (trigger another measurement and write to file).  This is why I can't simply use NI spy to listen.

 

I'm having trouble finding the proper block in LabVIEW that doesn't lock up the bus while listening.  Can someone advise what to use?

 

Thank  you!
