The module serial number.
Set by the manufacturer when the module passes final test during the manufacturing

The module software revision number.
Set by the software compilation process. This variable may be written to, but it is not
stored in non-volatile memory, so its value will revert to the ROM value on a power
cycle. In general, you can only use analyzers of a given revision level with control
modules of the same or higher level revision, at least up to revision 3.0..

Stores the values of the power supply voltages at manufacturing check out time.
Compare the present values to this in order to see what has changed. Only write into
this if the electronic hardware has been changed. There is a special function in the
manufacturing data screen which automatically stores this and other such variables.
