9 MAP OF REGISTERS OF ND30PNET METER
In ND30PNET meter the data is placed in 16- and 32-bit registers. Process variables and
parameters 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 in IEEE-754 standard. Bytes sequence
3210 – the oldest is sent first.
