Description: This value represents a bit-field of the various operational states of the PDU. The value is a logical OR of all of the following potential states of the PDU. Note the bit-position is given parenthetically next to the operational state in the description below. The bit position is assumed to be a big-endian format (least significant digit is the right-most digit). The state is present in the PDU when the bit is on (value = 1).

normalOperation(1) The PDU is operating normally with no active warnings or alarms. startUp(2) The PDU is in the startup state (initializing). Control and monitoring operations maybe inhibited or unavailable while the PDU is in this state. This state will clear automatically when the PDU(s) are fully initialized and ready to accept control and monitoring commands. normalWithWarning(8) The PDU is operating normally with one or more active warnings. Appropriate personnel should investigate the warning(s) as soon as possible and take appropriate action. normalWithAlarm(16) The PDU is operating normally with one or more active alarms. Appropriate personnel should investigate the alarm(s) as soon as possible and take appropriate action. abnormalOperation(32) The PDU is operating abnormally. That is there is some failure within the system that is unexpected under normal operating conditions. Appropriate personnel should investigate the cause as soon as possible. The normal functioning of the system is likely inhibited.
