If a function code is used on Modbus registers that are not listed (gray), a value of 0 or an exception code will be
returned.
Please note that little-endian is used when converting bytes to words in
an easyE4. If you want to implement Modbus communications with big-
endian, you will need to make the necessary adjustments.
