4.27  Status Subsystem Commands 
This subsystem programs the power source status registers. There are four groups of status registers; 
•  Operation Status Group 
•  Questionable Status Group 
•  Questionable Instrument ISummary Group 
•  Standard Event Group 
The Standard Event group is programmed with Common commands. The Operation, Questionable, 
and Instrument ISummary status groups each consist of the following three registers: 
Refer to chapter 7 for more information about the status registers.
