As the description states, this simply reports the state of the bin. Before trusting the optical power and DGD readings sitting in the rest of this same Curr 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 Curr 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.
