7.3.3 Operational Group (Status Register) Structure
Operational condition status register group holds a snapshot of the actual status state of the power
supply at a present time. Power supply status might quickly change its condition before the
controlling PC detects it. Events can be stored in the Event register if the Enable register allows it.
Refer to General Status Register Commands (section 5.10.9) set. Table 7-8 describes bit
configuration of the operational group register.

7.3.4 Command Error (“Cxx”)
Power supply responds with a command error if it receives an unrecognized command or a
command, which is recognized, but cannot be executed. Command error response format is
‘Cnn<CR>‘ where ‘nn’ is ‘01’ to ‘05’. The following execution error commands are available:
