基于C#的工业机器人上位机控制程序开发（搭配松下PLC + MC协议）

以下是为《基于C#的工业机器人上位机控制程序开发搭配松下PLC MC协议》这篇文章补充的更多实用代码示例覆盖工业现场最常遇到的功能模块。这些代码基于 .NET 8/9 自封装 MC 协议客户端2026年主流工业做法。1. 完整的心跳 自动重连机制工业必备publicclassPanasonicMCClientWithReconnect:IDisposable{privatereadonlystringip;privatereadonlyintport5000;privateTcpClientclient;privateNetworkStreamstream;privateCancellationTokenSourcectsnew();privateTaskheartbeatTask;publiceventActionstringOnConnectionStatusChanged;publicPanasonicMCClientWithReconnect(stringipAddress){ipipAddress;StartHeartbeat();}privatevoidStartHeartbeat(){heartbeatTaskTask.Run(async(){while(!cts.IsCancellationRequested){try{if(clientnull||!client.Connected){awaitReconnectAsync();}else{// 心跳读一个固定寄存器 D0假设始终为固定值vardataawaitReadWordDevicesAsync(D0,1);if(datanull||data.Length0)thrownewException(心跳失败);}}catch{OnConnectionStatusChanged?.Invoke(断开正在重连...);awaitTask.Delay(2000);}awaitTask.Delay(5000);// 每5秒心跳一次}});}privateasyncTaskReconnectAsync(){try{client?.Dispose();clientnewTcpClient();awaitclient.ConnectAsync(ip,port);streamclient.GetStream();OnConnectionStatusChanged?.Invoke(已连接);}catch{OnConnectionStatusChanged?.Invoke(连接失败);}}publicasyncTaskushort[]ReadWordDevicesAsync(stringdevice,intcount){if(clientnull||!client.Connected)returnnull;// 原有读逻辑...// 这里省略参考上一篇完整封装returnnewushort[count];// 简化示例}publicvoidDispose(){cts.Cancel();heartbeatTask?.Wait(1000);stream?.Dispose();client?.Dispose();}}2. 批量读取机器人多状态推荐方式减少通信次数// 假设PLC中机器人状态集中存储在 D1000 ~ D1019privateasyncTaskUpdateRobotMultiStatus(){try{vardataawaitmc.ReadWordDevicesAsync(D1000,20);// 示例映射根据你的PLC程序调整地址introbotRunningdata[0];// 0停止 1运行intcurrentProgNodata[1];// 当前程序号intalarmCodedata[2];// 主报警码intservoOndata[3];// 伺服使能状态intestopActivedata[4];// 急停信号floatcurrentSpeeddata[5]/10f;// 速度百分比放大10倍存储intposXdata[6];// 当前X位置脉冲或mmintposYdata[7];intposZdata[8];intposRdata[9];this.Invoke((MethodInvoker)delegate{lblRunning.TextrobotRunning1?运行中:停止;lblProgNo.Text$程序{currentProgNo:D3};lblAlarmCode.TextalarmCode0?无报警:$报警码{alarmCode:X4};lblServo.TextservoOn1?伺服ON:伺服OFF;lblEstop.TextestopActive1?急停触发:正常;lblSpeed.Text${currentSpeed:F1}%;lblPosition.Text$X:{posX}Y:{posY}Z:{posZ}R:{posR};});}catch(Exceptionex){lblStatus.Text读取状态失败ex.Message;}}3. 手动点动Jog控制带速度调节 安全检查privatefloatjogSpeedPercent10.0f;// 默认10%privateasyncvoidBtnJogAxis_MouseDown(objectsender,MouseEventArgse){if(!awaitCheckSafetyInterlock())return;ButtonbtnsenderasButton;stringaxisbtn.Tag?.ToString();// X, X-, Y, Y- 等// 写点动方向和速度awaitmc.WriteWordDeviceAsync(D300,(ushort)(jogSpeedPercent*10));// D300 速度放大10倍ushortdirectionCodeaxisswitch{X1,X-2,Y3,Y-4,Z5,Z-6,_0};awaitmc.WriteWordDeviceAsync(D301,directionCode);// D301 方向码// 启动点动M200 1 上升沿awaitmc.WriteBitDeviceAsync(M200,true);}privateasyncvoidBtnJogAxis_MouseUp(objectsender,MouseEventArgse){// 停止点动awaitmc.WriteBitDeviceAsync(M200,false);awaitmc.WriteWordDeviceAsync(D301,0);// 清方向}4. 报警历史记录与复位带时间戳 SQLiteprivateasyncvoidLogAlarm(intalarmCode){if(alarmCode0)return;stringdescGetAlarmDescription(alarmCode);// 自建报警码表usingvarconnnewSQLiteConnection(Data Sourcerobot_alarms.db);awaitconn.OpenAsync();usingvarcmdconn.CreateCommand();cmd.CommandText INSERT INTO AlarmLog (Timestamp, Code, Description) VALUES (ts, code, desc);cmd.Parameters.AddWithValue(ts,DateTime.Now);cmd.Parameters.AddWithValue(code,alarmCode);cmd.Parameters.AddWithValue(desc,desc??未知报警);awaitcmd.ExecuteNonQueryAsync();// UI显示最新报警this.Invoke(()lblLatestAlarm.Text$最新报警{alarmCode:X4}-{desc});}// 报警复位按钮privateasyncvoidBtnResetAlarm_Click(objectsender,EventArgse){if(!awaitCheckSafetyInterlock())return;// 写复位标志 M300 1 → 上升沿触发awaitmc.WriteBitDeviceAsync(M300,true);awaitTask.Delay(200);awaitmc.WriteBitDeviceAsync(M300,false);MessageBox.Show(报警已复位);}5. 产量/节拍统计每周期记录一次privateintcycleCount0;privateDateTimelastCycleTimeDateTime.Now;privateasyncvoidTimerCycle_Tick(objectsender,EventArgse){vardataawaitmc.ReadWordDevicesAsync(D500,1);// 假设D500为周期完成计数器intcurrentCycledata[0];if(currentCyclecycleCount){cycleCountcurrentCycle;varnowDateTime.Now;doublecycleTimeSec(now-lastCycleTime).TotalSeconds;lastCycleTimenow;this.Invoke((){lblCycleCount.Text$已完成周期{cycleCount};lblCycleTime.Text$本周期耗时{cycleTimeSec:F2}秒;lblUPH.TextcycleTimeSec0?$UPH{3600/cycleTimeSec:F1}:--;});// 可存入数据库做日报表}}这些代码片段覆盖了工业机器人上位机最核心的几个模块心跳重连、批量状态刷新、手动点动、安全联锁、报警管理、节拍统计。如果你希望进一步补充某个具体功能例如完整的报警码表 描述映射多机器人同时监控多实例 MCClient机器人位置实时曲线图ScottPlot触摸屏适配 高DPI处理离线模式 数据缓存请告诉我我可以继续给出更针对性的完整示例代码。
