The article describes how to set up a Modbus gateway to transfer data from Modbus TCP to Modbus RTU using Teltonika devices. The gateway functionality allows a Master device connected to the LAN port to send commands to a Slave device connected to the serial port (RS232, RS485 or USB). Steps are provided to configure the router, including enabling the serial interface, setting up the listening IP, port number, and slave ID, and adding IP addresses to the IP filter options. The article also provides steps to set up two PCs, one running a Modbus Master simulator and the other running a Modbus PLC simulator, to test the functionality.
