Commands for sending downlinks from Lorawan to Modbus

Commands for sending downlinks from Lorawan to Modbus

I have an AcuRev 2000 device connected to a UC300 controller via Modbus protocol.
In turn, this controller has the Lorawan protocol in which it can connect and send requested data to a platform.
The conflict is that I have the UC300 controller connected to its connector in Tago via HTTP but when I send the commands so that it reaches the controller and then via modbus it reaches the Acu-Rev 2000 and responds by sending the requested data, what I get is just data controller.
I would like a more practical guide where I can know how to connect and can request the data.
