CBA总决赛战报(稠州金租称坚决抵制歧视)

查询代码如下:

片头:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.IO.Ports;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

using 与变频器V90;

namespace 台达变

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

this.comboBox1.DataSource = SerialPort.GetPortNames();//获得端口

}

• ModbusRTU modbus = new ModbusRTU();

连接代码:

private void lianjie_Click(object sender, EventArgs e)

{

bool result = modbus.Open(this.comboBox1.Text);

if (result == false)

{

MessageBox.Show("串口连接失败", "建立连接");

}

else

{

modbus.prsSetSingleReg(1, 8193, Convert.ToInt16(Convert.ToSingle(this.knob_FreSet.Value) / 50.0f * 5000));

MessageBox.Show("串口连接成功", "建立连接");

}

• 正转代码:

private void buzhengzhuan_Click(object sender, EventArgs e)

{

if (!modbus.prsSetSingleReg(1, 8192, 0X22))

//if(!modbus.prsSetSingleReg(1, 99, 0x047F))

{

MessageBox.Show("正转失败");//这样就可以有返回值了

}

• 反转代码明细:

private void fanzhuan_Click(object sender, EventArgs e)

{

if (!modbus.prsSetSingleReg(1, 8192, 0x012))

{

MessageBox.Show("反转失败");

}

• 停止代码详细:

private void buSTOP_Click(object sender, EventArgs e)

{

//if(!modbus.prsSetSingleReg(1, 99, 0x047E)) //站号 寄存器地址 写入数据

if (!modbus.prsSetSingleReg(1, 8192, 0x01))

{

MessageBox.Show("停止失败");//这样就可以有返回值了

}

• 频率设置:

private void knob_FreSet_ValueChanged(object Sender)

{

//if (!modbus.prsSetSingleReg(1, 8193, Convert.ToInt16(Convert.ToSingle(this.knob_FreSet.Value) / 50.0f * 16384)))

if (!modbus.prsSetSingleReg(1, 8193, Convert.ToInt16(Convert.ToSingle(this.knob_FreSet.Value) / 50.0f *5000)))

{

MessageBox.Show("频率设置失败");

}

• 最后是要写一个类:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.IO.Ports;

using System.Threading;

namespace 与变频器V90

{

public class ModbusRTU

{

//创建对象

private SerialPort serialport = null;

//public 是可以给别人用的

public bool Open(string PortName)

{

//串口设置

serialport = new SerialPort(PortName, 9600, Parity.Even, 8, StopBits.One);

try

{

serialport.Open();

}

catch(Exception )

{

return false;

}

return true;

}

public void close()

{

if(serialport != null)

{

if (serialport.IsOpen)

{

serialport.Close();

}

}

}

public bool prsSetSingleReg(byte slaveld,short address,short value)

{

//发送报文 往40100这个地址写0X047E

List<byte> Sendcommand = new List<byte>();

Sendcommand.Add(slaveld);//站地址

Sendcommand.Add(0x06);//功能码

Sendcommand.Add((byte)(address / 256));//寄存器地址（0x00）

Sendcommand.Add((byte)(address % 256));//寄存器地址（0x63）实是99

Sendcommand.Add((byte)(value / 256));//写入数据（0x04）

Sendcommand.Add((byte)(value % 256));//（0x7F）

//CRC校验 的返回值

byte[] crc = CalculateCRC(Sendcommand.ToArray(), Sendcommand.Count);

Sendcommand.AddRange(crc);

serialport.Write(Sendcommand.ToArray(), 0, Sendcommand.Count);

//让正转哪些有反回数据

Thread.Sleep(50);

byte[] respOnse= new byte[count];

serialport.Read(response, 0, response.Length);

//让正反转有返回值作对比

return Encoding.ASCII.GetString(Sendcommand.ToArray()) == Encoding.ASCII.GetString(response);
