8.4. "03 (0x03) Read Holding Registers" function
This Modbus request is used to read a value continuously from contiguous inverter parameters.
Communication number of inverter parameter is set in hexadecimal. However, in the case of continuous
reading, communication number is rounded up at 0xA. For example, if you read inverter parameter
continuously from the parameter f109 (Communication No. is 0x0109), the next reading parameter is
f110 (Communication No. is 0x0110).
