C# 与欧姆龙CIP通信 C#读写代码

要在C#中与欧姆龙CIP进行通信，可以使用Socket进行读写，以下是一个简单的示例：

using System;
using System.Net.Sockets;

namespace CIPCommunication {
    class Program {
        static void Main(string[] args) {
            // 连接到PLC
            Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            socket.Connect("192.168.1.100", 44818);

            // 读取数据
            byte[] readBuffer = new byte[1024];
            byte[] command = new byte[] { 0x00, 0x00, 0x00, 0x02, 0x00, 0x04, 0x01, 0x0C };
            socket.Send(command);
            int bytesRead = socket.Receive(readBuffer);
            byte[] response = new byte[bytesRead];
            Array.Copy(readBuffer, response, bytesRead);

            // 写入数据
            byte[] writeBuffer = new byte[1024];
            byte[] command2 = new byte[] { 0x00, 0x00, 0x00, 0x02, 0x00, 0x06, 0x01, 0x0E, 0x00, 0x01 };
            socket.Send(command2);
            bytesRead = socket.Receive(writeBuffer);
            byte[] response2 = new byte[bytesRead];
            Array.Copy(writeBuffer, response2, bytesRead);

            // 关闭连接
            socket.Shutdown(SocketShutdown.Both);
            socket.Close();
        }
    }
}

这个示例连接到IP地址为192.168.1.100的PLC，然后发送读取和写入命令，最后关闭连接。具体的命令格式需要根据具体的PLC型号和通信协议来确定。
