Use the following procedure to read a setting value.
1. Set the command "0" in the "Command" area on PLC.
2. When AD-4411 accepts the command "0", it echoes back "0" in the "Response" area and waits for a
command from PLC.
3. Set a valid read command in the "Command" area on PLC.
4. If AD-4411 successfully reads the data, it echoes back the command in the "Response" area and updates
the read data in the "Response value" area. If it fails, the "Response" area is updated to 65535: Error.
