ata ：
03H ： Read data from registers ， can read several registers with the numbers less than 31 and only can read the data in the
same group every time.
06H : Write data into the register.
08H : Diagnosis
10H: write several data to register
（ 1 ） Function code 03H ： read register
For example ： Read data from address2104H （ Output current
） ：
RTU Mode ：
（ 2 ） Function code 06H ： Write to register
For example ： 01H ， write function code P0.02=50.00HZ .
RTU Mode ：
（ 3 ） Comm and mode ： 08H Diagnosis
This command is used for testing that if the communication between the client device ( master ) and inverter (slave) is
normal.Inverter will sent the d ata to control device.
