A parameter address is two bytes. Byte2 is the LSB, and Byte3 is the MSB. It indicates the
address of the parameter to be read or modified.
Parameter address representation rules: The MSB is the hexadecimal form of the number
before the dot mark, and LSB is that of the number behind the dot mark. Take P11.05 as
an example, the number before the dot mark is 11, that is, the MSB of the parameter
address is 0×0B; and the number behind the dot mark is 05, that is, the LSB is 0×01.
Therefore, the function code address is 0×0B05.
