Modbus RTU is typically RS485 as you mention. A Programmable Logic Controller, PLC or Programmable Controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. As such, this discussion will pertain solely to the RTU standard. Programming Arduino Uno as MODBUS Master. Modbus RTU is a relatively simple serial protocol that can be transmitted via traditional UART technology. PLEASE TRY OUR SCADA SOFTWARE WINTR. A primary goal was to enable industrial communication for the Arduino in order to link it to industrial devices such as HMIs, CNCs, PLCs, temperature regulators or speed drives. Modbus is a serial communications protocol, first used in 1979. 以下のライブラリを使用してarduinoコードを開発しました。私は、modbus RTUスレーブ上で正常に動作するコードをテストしました。今私は有線接続の代わりに無線LANにRS485を使用する予定です。.
