Some time this week, somebody changed PEM corner station model, and as a result it seems like one of the baffle diode channels, H2:PEM-CS_CHAN_30, is gone. The channel doesn't exist any more.

Please give us the baffle diode back. You don't have to revert the model back, all we need is another PEM channel (e.g. H2:PEM-CS_CHAN_26) and we'll fix our MEDM screen.
