8.1.5 Composite Data Message (aR0)
You can define the parameters to be included in the composite data message aR0 in the
parameter selection fields of each parameter (aWU,R, aTU,R, aRU,R, and aSU,R).
When changing the bits 9-16 of the parameter selection of any sensor, you can shorten the
command b
y replacing the bits 1-8 with a single '&' character, see the examples.
