This read-only Integer32 is a 32-bit bitmap dedicated to the PDU's receptacles rather than its overall phase/environmental sensors, where bit0 through bit31 each correspond to receptacle 1 through receptacle 32 and are set when that receptacle has dropped below its minimum current threshold, per the object's own description. An admin uses this single value to scan all 32 receptacles for threshold problems at once instead of checking each outlet's current reading individually. For example, if bit9 is set in recep1To32AlarmsMinMap, receptacle 10 is drawing less current than expected, which could mean the plugged-in device has lost power internally even though outlet10State still reads ON.
