(1100H～FFFFH)
*Note
In the function table, the MODBUS address coding rules:
high 8 bits HI = (Parameter group number + 1);
low 8 bits LO = (Function Parameter number).
The function parameter P0.11 can be only read. And function group PF can’t be read and
written.
Reading reserved address will return communication error code “02 H”.
