First, you posted to the wrong board. This has nothing to do with NI Switches. Should have posted to the Instrument Control Board.
Second, I have no idea what you have seen on the Forum since you did not provide any links but associating your error and a tag configuration makes no sense. You are getting an instrument specific error and has nothing to do with queues in LabVIEW. The error would be listed in the instrument manual.
Third, since the driver is not from NI and is an IVI driver, you really should contact the vendor since it is their code.
