Set Value (Signaling) using Displayed Units

[Hooovahh]

Not sure if you found a solution in the other replies, but I also suggest avoiding LabVIEW built in units.  They meet maybe 90% of the use cases, but this just might be one of the 10% that it won't.  I'm not too surprised mixing VI server stuff with the units stuff has issues.

Based on the test scenario that I presented, setting the text to "Inf" first fixes the problem.

Thanks!
