1648 +
1649 +
1650 +Users can use below the structure to fast debug the communication between RS485BL and RS485-LN. The principle is to put the PC in the RS485 network and sniff the packet between Modbus MTU and RS485-BL/LN. We can use this way to:
1651 +
1652 +1. Test if Modbus-MTU works with PC commands.
1653 +1. Check if RS485-LN sent the expected command to Mobus-MTU
1654 +1. Check if Modbus-MTU return back the expected result to RS485-LN.
1655 +1. If both b) and c) has issue, we can compare PC’s output and RS485-LN output.

Because the sensor to which the user is connected is custom, the read device data bytes also need custom parsing, so there is no universal decoder.
