The boolean variables seem to be indicated by "Yes". I think the "meter map" is 
the source of the numeric variables:

   0.566550     Index   Offset  Format  NUT
   0.566617     0027    0000    51      output.frequency

Maybe Alf has some additional insights?

I think Settings are what you would see from "upsrw <ups>", and Commands are 
listed by "upscmd -l <ups>". You're going to make me actually install the CGI 
programs, aren't you? Everything else I have been able to just look up in the 
source :-)

Right, or that the protocol doesn't expose the settings or commands.

The part that confuses me is why they would have the same firmware revision for 
what seem to be different sets of capabilities. Usually, the only internal 
difference between a 500 VA UPS and a 700 VA UPS is the size of the battery 
string and maybe the power electronics module.
