Board : Arduino UNO Additional Hi everyone, I'm newbie in this forum, this is my first post, if I have any mistake, please help me to fix it! Thanks! I'm writing new Modbus RTU library for arduino (master and slave) based on SimpleModbus. Modbus (rtu) network products Modbus rtu master slave Modbus (RS-485) Using Arduino. After the circuit connections are completed and the code is uploaded to the Arduino UNO, it’s time to connect the USB to RS-485 module with the PC where the Simple Modbus Master software is installed. The rs485 bus inlcudes one master (my pc via usb adapter), one opta and one energy meter. The different elements are highlighted, compatible libraries and boards Use Modbus equipment with your Arduino. Serial communication concerns the transmission of data in a serial manner, meaning it is sent and received one bit at a time. In Modbus RTU and Modbus Using TCP or RS485 shields, like the MKR 485 Shield. Improved by Łukasz Ślusarczyk.
