As the description states, this simply reports the state of the bin. Before trusting the OTU error and quality counters sitting in the rest of this same History row, checking this enumerated PmBinState value is how an operator confirms the bin actually ran its full interval rather than being partial, suspect, or invalid because of a mid-interval reset or a card reload. For example, if this State value on a History row comes back as anything other than a normal 'complete' indication, the averages and totals sitting beside it in that same row should be treated as only partially representative of that interval.
