Receiving data via modbus tcp

[Boobert21]

I have a PLC that broadcasts data. I tried to get this data using "easy modbus tcp", but I get ex "Starting address invalid or starting address + quantity invalid"

static void Modsim()
{
    ModbusClient modbusClient = new ModbusClient("10.7.0.2", 502);
    modbusClient.Connect();

    modbusClient.ReceiveDataChanged += ModbusClient_ReceiveDataChanged;
    Console.WriteLine("Receiving data:");

    int startingAddress = 49000;
    int quantity = 9;
    while (isChatRunning)
    {
        try
        {
            for (int i = startingAddress; i < startingAddress + quantity; i++)
            {
                modbusClient.ReadHoldingRegisters(startingAddress, quantity);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }
}

static void ModbusClient_ReceiveDataChanged(object sender)
{
    ModbusClient modbusClient = (ModbusClient)sender;

    string receivedData = BitConverter.ToString(modbusClient.receiveData.ToArray());

    if (receivedData.Length > 0)
    {
        Console.WriteLine(receivedData);
    }

    Thread.Sleep(1000);
}

So far I'm training on modsim32. These are the values I have set:
Address: 9000
Length: 10
Device id: 1
Modbus Point Type: 03: Holding Register
IP: 127.0.0.1, Port: 502

Please tell me what I did wrong. Or what I didn't. I would be glad for any information)

I see 49000 in place of 9000? That might have an impact?
