6. MAP OF MODBUS REGISTERS
In N20Z PLUS meter the data is placed in 16- and 32-bit registers. Parameters
and measured values of the meter are located in the address space of registers in a
manner dependent on the type of the variable. Bits in 16-bit registers are numbered
from the youngest to the oldest (b0-b15). 32-bit registers contain floating point
numbers. The list of available registers is shown in Table 3. The ranges of changes
in the value of registers are presented in tables 4 and 5.
