Only allow root fault bit to come on, mask resulting subsequent faults

[flylikechris]

Hi all, I have some machines that may fault due to one problem, but because of that fault I get maybe twenty other fault bits as a result. I think it would be nice to mask these nuisance faults and only allow the primary root fault bit to come high. If this were written in a scripted language I might use this structure: while (not "faulted")

If they are actually caused by the first fault they are not really faults and should be ignored. What you have is a poorly written fault routine, or fault reporting routine. I would think this tolerable if the faults are presented in an order that makes it clear which one is the trigger and it must be taken care of first, releasing the others without further operator action.
