Arduino Modbus Server that converts Arduino Board to Modbus RTU server. Use any Modbus RTU Client (Master) to poll Arduio IO or Analog Value. Example of using ModbusMonitor XPF programto read IO from Arduino IO. More information atwww.QuantumBitSolutions.com ...
I am a beginner. I am trying to communicate (read values) with a device and the modbus address is ranging from 40200 to 40380. I am using max 485 ic to convert rtu to ttl. But on the serial monitor it is showing some garbage value. Is something missing in the code. I have seen...
ESP32 modbus RTU程序。 用arduino IDE开发的ESP32 modbus RTU slave程序。 不是库文件,直接用子程序编写,已注释了代码,容易看懂和移植。 已通讯连接成功。 程序已在多个项目上应用,不用怀疑:有气压检测设备,风机加热器控制箱,恒温控制箱,拉挤设备。 细心调试代码你可以快速成功的。
