Как читать 4 байтовый данных в Easymodbus tcp

Span<byte> span = GetFromNetwork();
span.Reverse();
int val = BitConverter.ToInt32(span);

int networkValue = GetFromNetwork();
var hostValue = IPAddress.NetworkToHostOrder(networkValue);

namespace EasymodbusTCP

    public partial class Form1 : Form

        private int[] read_packed = new int[32];
        ModbusClient modbusClient = new ModbusClient("10.0.6.10", 502);

        public Form1()
        {
            InitializeComponent();
           
            modbusClient.Connect();
            modbusClient.ConnectionTimeout = 50;
            
        }
 
        private void timer1_Tick(object sender, EventArgs e)
        {
            read_packed = modbusClient.ReadInputRegisters(0,24);
         }

            int intreg = ModbusClient.ConvertRegistersToInt(modbusClient.ReadHoldingRegisters(22, 2), ModbusClient.RegisterOrder.LowHigh);
            int intreg2 = ModbusClient.ConvertRegistersToInt(modbusClient.ReadHoldingRegisters(24, 2), ModbusClient.RegisterOrder.LowHigh);
