Register layout:
Register addresses are specified as decimal numerals.
Input registers are placed in the address area 30001..39999.
Holding registers are placed in the address area 40001..49999.
NOTE:
In the following tables, the register addresses applied in the MODBUS messages are without the
global offset. This means that if you read input register 100 with function code 04, you will get the
global address 30101.
NOTE:
All input registers can also be read as type holding register with function code 03 by adding the
offset value 10000 to the register address. No writes will be accepted in this range.
Register groups
The protocol data is grouped into the following address ranges with 100 registers in each group.
This applies to both input and holding register types:
