First, deduct 100 from 195 and get 95. Next, invert 95 to hexadecimal H5F. Finally, convert 5 and F to ASCII
CODE H35 and H46.
Step4. After the inverter receiving the information and processes it correctly, the inverter will send
the value of P.195 to the computer via format E:

Example 4.
Change the value of P.195 to 50 (the initial value is 60):
Step1 and 2 of this example are similar to Step1 and 2 of Example 3.
Step 3. The computer requests the inverter to enter 50 into P.195 via format A:
