modbus programming in c# (tcp/rtu) full example projects

以下是使用C＃编写Modbus TCP / RTU通信的示例项目：
Modbus TCP通信示例项目：
using System;
using System.Net.Sockets;
using System.Threading;
using System.Windows.Forms;
using EasyModbus;
namespace ModbusTCPSlaveExample
    public partial class Form1 : Form
        private ModbusServer modbusServer;
        private Thread serverThread;
        public Form1()
            InitializeComponent();
            modbusServer = new ModbusServer();
            modbusServer.Listen();
            serverThread = new Thread(new ThreadStart(UpdateServer));
            serverThread.Start();
        private void UpdateServer()
            while (true)
                    modbusServer.Coils[0] = checkBox1.Checked;
                    modbusServer.Coils[1] = checkBox2.Checked;
                    modbusServer.Coils[2] = checkBox3.Checked;
                    modbusServer.Coils[3] = checkBox4.Checked;
                    modbusServer.HoldingRegisters[0] = Convert.ToInt32(textBox1.Text);
                    modbusServer.HoldingRegisters[1] = Convert.ToInt32(textBox2.Text);
                    modbusServer.HoldingRegisters[2] = Convert.ToInt32(textBox3.Text);
                    modbusServer.HoldingRegisters[3] = Convert.ToInt32(textBox4.Text);
                catch (Exception ex)
                    Console.WriteLine(ex.Message);
                Thread.Sleep(50);
Modbus RTU通信示例项目：
using System;
using System.IO.Ports;
using System.Threading;
using System.Windows.Forms;
using EasyModbus;
namespace ModbusRTUSlaveExample
    public partial class Form1 : Form
        private ModbusServer modbusServer;
        private Thread serverThread;
        private SerialPort serialPort;
        public Form1()
            InitializeComponent();
            modbusServer = new ModbusServer();
            modbusServer.Listen();
            serverThread = new Thread(new ThreadStart(UpdateServer));
            serverThread.Start();
            serialPort = new SerialPort();
            serialPort.PortName = "COM1";
            serialPort.BaudRate = 9600;
            serialPort.Parity = Parity.None;
            serialPort.StopBits = StopBits.One;
            serialPort.DataBits = 8;
            serialPort.Open();
            modbusServer.SerialPort = serialPort;
        private void UpdateServer()
            while (true)
                    modbusServer.Coils[0] = checkBox1.Checked;
                    modbusServer.Coils[1] = checkBox2.Checked;
                    modbusServer.Coils[2] = checkBox3.Checked;
                    modbusServer.Coils[3] = checkBox4.Checked;
                    modbusServer.HoldingRegisters[0] = Convert.ToInt32(textBox1.Text);
                    modbusServer.HoldingRegisters[1] = Convert.ToInt32(textBox2.Text);
                    modbusServer.HoldingRegisters[2] = Convert.ToInt32(textBox3.Text);
                    modbusServer.HoldingRegisters[3] = Convert.ToInt32(textBox4.Text);
                catch (Exception ex)
                    Console.WriteLine(ex.Message);
                Thread.Sleep(50);
这些示例项目使用EasyModbus库来实现Modbus通信。请注意，这些示例项目是基本的示例，您可以按照您的实际需求进行修改。
