Can a Modbus RTU to Modbus TCP Converter Handle Multiple Modbus RTU Devices on a Single Serial Line?

The answer is ‘Yes’, Many converters support multi-drop configurations, where multiple Modbus RTU devices are connected on a single RS-485 serial line. The converter uses the device IDs of the RTU devices to route requests and responses between the Ethernet-based Modbus TCP clients and the correct serial device. However, network performance may depend on the number of devices and polling frequency.
