Appendix-2: Modbus List
While reading data through MODBUS, the following addresses can be used. "03 - Read Holding Registers"
must be selected to read the MODBUS data.
We can send commands by using MODBUS. To do that function 06 – Write Single Register must be used.
The data is defined as unsigned words (2 bytes).
