Input registers are not tied to classic 4xxxx and 3xxxx areas. There are also many registers that has
the same register number but the function depends on the register type.
For example, a transmitter with ID1 has an input register for temperature (20051) and holding register
for COV limit (20051). The address is the same, but the register usage depends on the used function
code.
Important: Some BMS systems may need extra configuring to able to use the whole
register space. Contact the system vendor support if needed.
The following figure illustrates how the basic data can be read via base unit Modbus registers.
