安装欧姆龙PLC开发软件安装工具CX-Compolet_SGW_Ver1.72在Network Browser》Control Panel》Network Configuration》EtherNet/IP Hardware》Communications Adapter》如果使用网管更改ip地址 启动网关。点击Start如果有对应Open状态就可以负责勾选上下面的Extend the Ethernet ports后再Start PLC上配置IP地址连接成功后更改IP地址 更改后连接的IP地址设置如果这里不更改一致无法实现在线测试更改 上方工具栏》控制器》通信设置》远程IP地址 PLC添加可被外部读取的全局变量 上位机代码实现
依赖项Nuget中搜索CIPCompolet添加
using OMRON.Compolet.CIP;internal class MyCIP
{NXCompolet nXCompolet; // 欧姆龙的CIP通讯Mutex mutex new Mutex(); // 进程间互斥锁public MyCIP() {Conncet(192.168.50.1); // 192.168.50.1; 127.0.0.1}public void Conncet(string ip){Task.Run(() {nXCompolet new NXCompolet(new Container());nXCompolet.PeerAddress ip;while (true){mutex.WaitOne();Console.WriteLine(RunStatus: nXCompolet.RunStatus ; PeerAddress: nXCompolet.PeerAddress);Console.WriteLine(port: nXCompolet.LocalPort);//Console.WriteLine(UnitName: nXCompolet.UnitName ,DontFragment: nXCompolet.DontFragment);nXCompolet.Active true;if (!nXCompolet.IsConnected){nXCompolet.Active false;Console.WriteLine(PLC连接错误);Thread.Sleep(1000);continue;}Console.WriteLine(PLC连接成功);//nXCompolet.RunMode NXCompolet.RunModeTypes.Program;object obj nXCompolet.ReadVariable(gbHMI_CloseDoor);Console.WriteLine(obj.ToString());mutex.ReleaseMutex();Thread.Sleep(1000);}});}
}
运行结果
RunStatus: 1; PeerAddress:192.168.50.1 port: 2 PLC连接成功 True
抓取报文
安装wireshark抓取 使用欧姆龙附带的调试工具
更改IP后勾选上Active进入连接状态
