Notes:
If there is no need to keep the parameters permanently, it suffices to write the parameters to the RAM area.
However, if the parameters have to be maintained permanently, it is required to write the parameter values
into the ROM area. The service life of ROM area will be shortened if parameters are frequently written to
the ROM area. If value F2.1.13 needs to be written and maintained permanently, the register address
where it should be written to is 0xE213.
When reading/writing controlling characters, it can be achieved via reading/writing to the coil mapped to
each digit of controlling characters, and it can also be achieved via reading/writing to the hold register
corresponding to the controlling characters. Both methods can achieve identical results. If it is needed to
set the value for operation allowed，we can set the value of the digit 1 for controlling character (address
0x1001) as 1 Via functional code 05, we can also set the value of controlling character (address 0x1300)
as 0x0002 via functional code 06. When reading the status characters, the method is similar to that for
reading/writing controlling characters. It can be achieved via reading the discrete input mapped to each
digit of status characters, and it can also be achieved via reading the hold register corresponding to the
status characters. If we need to read the operation direction, we can read the status digit 5 (address
0x1105) via functional code 02, we can also read the status character (address 0x1309) via functional
code 03.
