Modbus error
#4
Physical connection might not be correct. Check A/B: sometimes they are marked incorrectly and have to be swapped. Check if GND is connected between LM and ModBus device because it might not work without it in some cases. Another thing to check is correct baud rate, parity/stop bits and slave address.
