8.6. "16 (0x10) Write Multiple Registers" function
This Modbus request is used to write a value continuously to contiguous inverter parameter.
Communication number of inverter parameter is set in hexadecimal. However, in the case of continuous
writing, communication number is rounded up at 0xA. For example, if you write inverter parameter
continuously from the parameter f109 (Communication No. is 0x0109), the next writing parameter is
f110 (Communication No. is 0x0110).
