using EasyModbus;

using System.Net.Sockets;

namespace AC_C_Demo

{

/// <summary>

public sealed partial class MainPage : Page

{

private ModbusClient modbusClient;

public MainPage()

{

this.InitializeComponent();

modbusClient = new ModbusClient("192.168.0.3", 502); // Replace with your device's IP address and port

ReadModbusData_Click();

}

private async void ReadModbusData_Click()

{

modbusClient.Connect();

while (true)

{

// Read input 1

bool i1Value = modbusClient.ReadDiscreteInputs(0, 1)[0];"I1"

// Read output 1

bool q1Value = modbusClient.ReadCoils(0, 1)[0];

// Read output 1

bool q2Value = modbusClient.ReadCoils(1, 1)[0];

// Display the values in TextBlocks

InputStatusTextBlock.Text = "I1: " + i1Value.ToString();

//   Q1ValueTextBlock.Text = "Q1: " + q1Value.ToString();

//   Q2ValueTextBlock.Text = "Q2: " + q2Value.ToString();

}

}

}

}

however the linebool i1Value = modbusClient.ReadDiscreteInputs(0, 1)[0];is giving me the following error:

System.IO.IOException:'Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.'

SocketException: An existing connection was forcibly closedbythe remote host

I do not know what is causing it, I have the device connected by Ethernet and have already configured my connection to be in range an i tested if it is connected by opening a browser and going to the device ip and it took me the to web interface of the device and i was able to detect the signals of the program i have installed, and I already tried turning off my firewall and nothing changed.

the program running on it, it is a simple test program that if input i1 is on(true) output 1Q and Q2 will turn one Q1 will turn on after 1 sec and Q2 will turn on after 3 sec, same thin when input i1 is turned off, the point of my program is to detect the status changes in these three registers and put these status on a textblock i have made in visual studio.

or is there a better way to do what am trying to achieve?
