4. Refer to the field "Protocol Description" at the top right of the program. You can send
a request command and confirm the response is correct.
(Ex: If the remote Modbus device ID = 1, you send “1 2 0 0 0 4” for reading D/I value,
you may receive response “1 2 1 0 A1 88”) (“A1 88” is the CRC value.)
Note: The response is depending on the connected Modbus device.
