問題是我是一個(gè)PLC工程師，想用寫一個(gè)上位機(jī)程序和三菱FX3U通訊，PLC的IP地址為192.168.0.250，端口號(hào)為5551.要求顯示X0到X7，輸出顯示Y0到Y(jié)7，還有M0到M9切換按鈕，輸出格式為直接打開的exe文件
以下是使用C#開發(fā)的三菱FX3U上位機(jī)通信程序?qū)崿F(xiàn)方案，包含可直接運(yùn)行的EXE文件生成方法：
一、開發(fā)環(huán)境配置
‌開發(fā)工具‌：
Visual Studio 2022 (社區(qū)版)
.NET Framework 4.8
通信參數(shù)‌
NuGet包：Mx.Component.Melsec（三菱協(xié)議庫）
var config = new MelsecConfiguration {
    ProtocolType = ProtocolType.TCP,
    Host = "192.168.0.250",
    Port = 5551,
    CpuType = CpuType.FX3U,
    ConnectTimeout = 3000
};
二、界面設(shè)計(jì)（Windows Forms）
<!-- MainForm.Designer.cs -->
this.Controls.AddRange(new Control[] {
    // X0-X7狀態(tài)指示燈
    new StatusLight { Name="x0", Location=new Point(20,20) },
    // ...重復(fù)創(chuàng)建x1-x7
    
    // Y0-Y7狀態(tài)顯示
    new StatusLight { Name="y0", Location=new Point(120,20) },
    // ...重復(fù)創(chuàng)建y1-y7
    
    // M0-M9切換按鈕
    new ToggleButton { Name="m0", Text="M0", Location=new Point(220,20) },
    // ...創(chuàng)建m1-m9
    
    // 狀態(tài)欄
    new StatusStrip {
        Items = {
            new ToolStripStatusLabel { Name="lblStatus" }
        }
    }
});
三、核心通信代碼
public partial class MainForm : Form {
    private MelsecFxPLC plc;
    
    // 初始化PLC連接
    private void ConnectPLC() {
        plc = new MelsecFxPLC(config);
        var result = plc.Connect();
        
        if (result.IsSuccess) {
            timer1.Interval = 500;  // 500ms輪詢周期
            timer1.Start();
        }
    }

    // 定時(shí)讀取狀態(tài)
    private void timer1_Tick(object sender, EventArgs e) {
        // 批量讀取X/Y狀態(tài)
        var xStatus = plc.ReadBytes("X0", 1);
        var yStatus = plc.ReadBytes("Y0", 1);
        
        // 更新指示燈
        UpdateLights(xStatus, "x");
        UpdateLights(yStatus, "y");
    }

    // M按鈕點(diǎn)擊事件
    private void mButton_Click(object sender, EventArgs e) {
        var btn = sender as ToggleButton;
        plc.WriteBit($"M{btn.Tag}", btn.Checked);
    }
}
四、可視化組件類
// 狀態(tài)指示燈控件
public class StatusLight : PictureBox {
    public StatusLight() {
        Size = new Size(30, 30);
        BackColor = Color.Silver;
    }

    public bool Active {
        set => BackColor = value ? Color.Lime : Color.Red;
    }
}

// 切換按鈕控件
public class ToggleButton : CheckBox {
    public ToggleButton() {
        Appearance = Appearance.Button;
        TextAlign = ContentAlignment.MiddleCenter;
        Size = new Size(50, 30);
    }
}
五、項(xiàng)目打包部署
‌發(fā)布設(shè)置‌：

項(xiàng)目屬性 → 發(fā)布 → 選擇"從CD/USB安裝"
包含.NET Framework 4.8運(yùn)行庫
生成單文件EXE
‌依賴文件‌
├── MelsecFx.dll
├── Newtonsoft.Json.dll
└── Mx.Component.Core.dll
六、協(xié)議處理流程圖
sequenceDiagram
    participant UI as 上位機(jī)
    participant PLC as FX3U PLC
    
    UI->>PLC: TCP Connect(192.168.0.250:5551)
    PLC-->>UI: 連接成功響應(yīng)
    
    loop 500ms輪詢
        UI->>PLC: 讀取X0-X7(0x00B0命令)
        PLC-->>UI: X狀態(tài)數(shù)據(jù)
        UI->>PLC: 讀取Y0-Y7(0x00B0命令)
        PLC-->>UI: Y狀態(tài)數(shù)據(jù)
    end
    
    UI->>PLC: 寫入M位(0x1401命令)
    PLC-->>UI: 寫入確認(rèn)
七、測試驗(yàn)證步驟
‌PLC準(zhǔn)備‌：
; 測試程序
LD M8000
MOV K85 K1Y0  // Y0-Y7循環(huán)顯示
‌上位機(jī)操作檢查表‌：
