According to the operating instructions, the converter can only use Modbus RTU. And the heading of your topic is RTU, not TCP / IP. It will probably not work without a gateway. Modbus TCP / IP and Modbus RTU are different, physical protocols. Modbus TCP / IP is Ethernet, Modbus RTU is RS485.

No sé si esto se ajusta a su VFD, ya que no proporciona ninguna información específica. Después de estas instrucciones, creé un intercambio de datos.
