Bit Bit Weight Bit Name Description
0 1 Operation
Complete
(OPC) Set if KOPC command has been received
and all pending operations have been
completed. The message, Event –800

4 16 Execution Error
(EXE) Set if a program data element, following a
header, was evaluated by the power
supply as outside of its legal input range,
or is otherwise inconsistent with the power
supply’s capabilities. Suggests that a valid
