Modbus RTU means that the Modbus protocol is used on top of a serial RS232 or RS485 interface connection, meanwhile Modbus TCP is used over the network. In this configuration example we will show you how to transmit data between these connections. To understand the setup better, here is connection topology:

Here you can see that the Slave device is connected to the Serial port and Master is connected to LAN port and it sends it's commands through TCP.
