C# modbus Tcp协议数据抓取和使用
基于Modbus tcp 协议的数据抓取,并解析,源码使用C#开发
using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Net.Sockets; using System.Text; namespace modbus { class Program { #region 字节转换为16进制字符 /// <summary> /// 字节转换为16进制字符 /// </summary> /// <param name="data"></param> /// <returns></returns>jiang static string ByteToHexString(byte[] data) { string strTemp = ""; for (int i = 2; i < data.Length; i++) { string a = Convert.ToString(data[i], 16).PadLeft(2, '0'); strTemp = strTemp + a; } return strTemp.Substring(0, 100); } #endregion #region 16进制字符转换为字节 /// <summary> /// 16进制字符转换为字节 /// </summary> /// <param name="hs"></param> /// <returns></returns> static byte[] HexString(string hs) { hs = hs.Replace(" ", ""); string strTemp = ""; byte[] b = new byte[hs.Length / 2]; for (int i = 0; i < hs.Length / 2; i++) { strTemp = hs.Substring(i * 2, 2); b[i] = Convert.ToByte(strTemp, 16); } return b; } #endregion #region 发送、接收报文并返回报文 /// <summary> /// 發送或接受風機指令 /// </summary> /// <param name="sendCodeMeg">指令</param> /// <param name="IpAddress">IP地址</param> /// <param name="panelIP">面板IP</param> /// <returns></returns> static string SendPack(string sendCodeMeg, string IpAddress, int port) { IPAddress ip = IPAddress.Parse(IpAddress); Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); try { Console.WriteLine("開始發送數據。。。"); clientSocket.Connect(new IPEndPoint(ip, port)); //配置服务器ip和端口 //TcpClient tcpClient = new TcpClient(); Console.WriteLine("服务器连接成功"); } catch { Console.WriteLine("连接服务器失败\n"); return null; } try { string sendMessage = sendCodeMeg; // "6B 00 00 00 00 06 02 06 05 10 00 01"; //发送到服务端的内容 var sendData = HexString(sendMessage); string recvStr = null; int bytes; try { Console.WriteLine("发送报文:{0}", sendMessage); clientSocket.Send(sendData);//向服务器发送数据 byte[] recvBytes = new byte[1024]; //连接时长500ms clientSocket.ReceiveTimeout = 5000; bytes = clientSocket.Receive(recvBytes, recvBytes.Length, 0); //服务端接受返回信息 recvStr += ByteToHexString(recvBytes); } catch (Exception ex) { Console.WriteLine("出现错误!\n{0}\n\n", ex); recvStr = null; } if (recvStr != null) { Console.WriteLine("获取成功!\n 获得数据:{0}\n\n", recvStr); } clientSocket.Close();//关闭连接释放资源 //Console.ReadLine(); return recvStr; } catch { Console.WriteLine("出现错误!\n"); return null; } } #endregion //主函数 static void Main(string[] args) { Console.WriteLine("开始!"); string IP = "10.139.49.61"; int port = 502; int fnu = 4; string a = fnu.ToString("x2"); string sendCodeMeg1 = "02 00 00 00 00 06 01 03 01 10 00 02"; string sendCodeMeg2 = "03 00 00 00 00 06 01 03 01 0A 00 02"; string data1 = null; string data2 = null; for (int num = 0; num < 5; num++) { Console.WriteLine("第{0}次调用Get_Fan函数!\n", num + 1); data1 = SendPack(sendCodeMeg1, IP, port); if (data1 != null) { break; } } for (int num = 0; num < 5; num++) { Console.WriteLine("第{0}次调用Get_Fan函数!\n", num + 1); data2 = SendPack(sendCodeMeg2, IP, port); if (data2 != null) { break; } } Console.WriteLine("结束"); Console.ReadKey(); } } }
C# modbus tcp读写数据
1.引用-添加引用-HslCommunication.dll
2.ModBus组件所有的功能类都在 HslCommunication.ModBus命名空间,所以再使用之前先添加
using HslCommunication.ModBus; using HslCommunication;
3.在使用读写功能之前必须先进行实例化:
private ModbusTcpNet busTcpClient = new ModbusTcpNet("192.168.3.45", 502, 0x01); // 站号1
上面的实例化指定了服务器的IP地址,端口号(一般都是502),以及自己的站号,允许设置为0-255,后面的两个参数有默认值,在实例化的时候可以省略。
private ModbusTcpNet busTcpClient = new ModbusTcpNet("192.168.3.45"); // 端口号502,站号1
4.
- 模拟器模拟的是西门子PLC 有四种类型
- 地址以0开头的是可读可写线圈
- 地址以1开头的是只读线圈
- 地址以4开头的是可读可写寄存器(string/float/int/ushort/short等都可以放在这里面)
- 地址以3开头的是只读寄存器
- 我们读取的时候只看后四位0001,就是1,但是库里面是从0开始读的,所以对应的就要减一
5.读取寄存器的一个值
private void button1_Click(object sender, EventArgs e) { bool coil100 = busTcpClient.ReadCoil("0").Content; // 读取线圈1的通断 int int100 = busTcpClient.ReadInt32("0").Content; // 读取寄存器1-2的int值 float float100 = busTcpClient.ReadFloat("0").Content; // 读取寄存器1-2的float值 double double100 = busTcpClient.ReadDouble("0").Content; // 读取寄存器1-3的double值 }
6.读取寄存器的一组值(一组线圈)(一组float值)
private void button3_Click(object sender, EventArgs e) { //读取地址为0,长度为3的线圈数量 OperateResult<bool[]> read = busTcpClient.ReadCoil("0", 3); if (read.IsSuccess) { for (int i = 0; i < read.Content.Length; i++) { Console.WriteLine(read.Content[i]); } } else { MessageBox.Show(read.ToMessageShowString()); } //读取(一组)寄存器数据 OperateResult<float[]> result = busTcpClient.ReadFloat("0", 4); if (result.IsSuccess) { //Console.WriteLine(result.Content[0]); //Console.WriteLine(result.Content[1]); //Console.WriteLine(result.Content[2]); for (int i = 0; i < result.Content.Length; i++) { Console.WriteLine(result.Content[i]); } } else { MessageBox.Show(result.ToMessageShowString()); } }
7.写入一个(线圈)(寄存器)
private void button2_Click(object sender, EventArgs e) { busTcpClient.WriteCoil("0", true);// 写入线圈1为通 busTcpClient.Write("0", 123.456);// 写入寄存器1-2为123.456 }
8.批量写入一组(线圈)(寄存器)
private void button9_Click(object sender, EventArgs e) { //写入一组线圈 bool[] value = new bool[] { true, true, false, true, false }; busTcpClient.WriteCoil("0", value); } private void button10_Click(object sender, EventArgs e) { //写入一组寄存器 float[] value = new float[] {1.1F, 1.2F, 1.3F, 1.4F, 1.5F }; busTcpClient.Write("0", value); }

以上为个人经验,希望能给大家一个参考,也希望大家多多支持我们。
