Monitor limits consists of lower and upper limits of each monitored
value; the lower limit is first followed by the upper limit. Each
limit is an eight bit unsigned integer; the monitored value is scaled
accordingly before being monitored.

Parameters are constants that describe different characteristics of the
system. In recognition of the fact that we may not know these
"constants" exactly and may want to change them after launch, the
parameters are grouped together in a parameter database.
