    Hello.
    Let me start by saying that this is a completely new challenge for me, and all the knowledge I have been able to acquire I have found on various forums.
    The matter is as follows. I decided to connect an air conditioning monitoring device in a building to a computer via Modbus. I communicated the device using a USR TCP232-410s converter. On the RS485 side of the device, an ethernet cable followed. I then set the correct parameters with ModbusTool and started trying to read the register values. Here lies the problem, which I have been pondering for a while now. I cannot read the values for the ModbusTool properly.
    How do I read register values in ModbusTool from an air conditioning monitoring device? .
    Could someone please help me decipher these values.
    Thank you in advance.

    P.S
    Please find attached the documentation of the registers.
