PCE-ND10 meter register map
PCE-ND10 meter has data contained in 16-bit and 32-bit
registers. Process variables and meter parameters are placed
in the address area of registers in a way depended on
the variable value type. Bits in 16-bit registers are numbered
from the youngest to the oldest (b0-b15). 32-bit registers include
num-bers of float type in IEEE-754 standard. Sequence of
3210 bytes – the oldest is transmitted as the first.
