Modbus RTU ⇒ Modbus TCP/UDP Gateway Arduino-based Modbus RTU to Modbus TCP/UDP gateway with web interface. Allows you to connect Modbus RTU slaves (such as sensors, energy meters, HVAC devices) to ...

1. Send Modbus-RTU command to the device through RS-485 via Serial3. 2. Get responses from the device through RS-485. 3. Send the device responses to the human-machine interface (HMI) via Serial1. 4.

In the Arduino automation area, the Modbus RTU protocol is a means of communication that allows the exchange of data between programmable logic controllers (industrial PLC controller Arduino) and ...

Abstract: This paper presents the design and implementation of a multipurpose networked control system using Arduino and Modbus RTU over RS-485 communication. The system enables robust and scalable ...
