Hi all!
I have connected a temperature sensor that supports RS485, I have tested it with modbus poll and it works ok. But when I connect to LM, it gives an error when I receive the command, I send the command also the error, did I configure the rs485 Bus correctly as the document and like modbus poll ?
I don't know where the error is, please help me!
