C#上位机与欧姆龙PLC的通信09----开发专用的通讯工具软件(Winform版)

1、介绍

上节文章已经完成了通讯库的开发，可以看到库还是蛮厉害的，在项目中就可以直接拿来应用，这节要做的就是做一个工具软件，形成自己专业的通讯工具，也是对通讯库的直接利用，本节要写的工具软件是一个winform程序，因为控制台程序是单调的，不方便操作，不直观。

2、开始干

1、添加窗体程序

2、引用通讯库文件.dll

将上节生成的dll文件复制到本项目中

3、连接代码

using Omron.Communimcation.Fins.Omron;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace OmronFinsFormApp
{
    public partial class Form1 : Form
    {

        /// <summary>
        /// finstcp对象
        /// </summary>
        FinsTcp finsTcp;

        public Form1()
        {
            InitializeComponent();
        }

        /// <summary>
        /// 连接Plc
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void btnOpen_Click(object sender, EventArgs e)
        {
            string ip = txtIPAddress.Text.Trim();
            string port = txtPort.Text.Trim();
            finsTcp = new FinsTcp(ip, Convert.ToInt32(port), (byte)10, (byte)04);// 创建连接 
            var result = finsTcp.Connect();// 开始连接PLC
            if (!result.IsSuccessed)
            {
                MessageBox.Show(result.Message);
                return;
            }
            lblMessage.Text = "PLC连接成功";
            SetTextDisable(true);
            this.btnOpen.Enabled = false;
            this.btnClose.Enabled = true;
        }

        private void SetTextDisable(bool v)
        {
            txtIPAddress.ReadOnly = v;
            txtPort.ReadOnly = v;
        }

    }
}

4、读取代码

  /// <summary>
  /// 读取数据
  /// </summary>
  /// <param name="sender"></param>
  /// <param name="e"></param>
  private void myread_Click(object sender, EventArgs e)
  { 
      //内存地址
      string plcAddr = txtMemoryAddr.Text.Trim( ); 
      //读取数量
      ushort readCount = ushort.Parse(txtRCount.Text.Trim( ));
      //数据类型
      string dataType = cbodatatype.Text.Trim();
      switch (dataType)
      {
          case "ushort":
              var datas= finsTcp.Read<ushort>(plcAddr, readCount);
              if (!datas.IsSuccessed)
              {
                  MessageBox.Show(datas.Message);
                  return;
              }
              txtReadDatas1.Text = string.Join(",", datas.Datas);
              break;
          case "short":
              var datas2 = finsTcp.Read<short>(plcAddr, readCount);
              if (!datas2.IsSuccessed)
              {
                  MessageBox.Show(datas2.Message);
                  return;
              }
              txtReadDatas2.Text = string.Join(",", datas2.Datas);
              break;
          case "float":
              var datas3 = finsTcp.Read<float>(plcAddr, readCount);
              if (!datas3.IsSuccessed)
              {
                  MessageBox.Show(datas3.Message);
                  return;
              }
              txtReadDatas3.Text = string.Join(",", datas3.Datas);
              break;
          case "bool":
              var datas4 = finsTcp.Read<bool>(plcAddr, readCount);
              if (!datas4.IsSuccessed)
              {
                  MessageBox.Show(datas4.Message);
                  return;
              }
              txtReadDatas4.Text = string.Join(",", datas4.Datas);
              break;
      }
  }

通讯报文

5、写入代码

  /// <summary>
  /// 写入数据
  /// </summary>
  /// <param name="sender"></param>
  /// <param name="e"></param>
  private void btnWrite_Click(object sender, EventArgs e)
  {
      //PLC地址
      string plcAddr = txtWPLCAddr.Text.Trim();
      //数据类型
      string dataType = cmddatatype2.Text.Trim();
      //实际数量
      string objWriteVals = "";
      switch (dataType)
      {
          case "ushort":
              objWriteVals = txtWriteDatas1.Text.Trim();
              break;
          case "short":
              objWriteVals = txtWriteDatas2.Text.Trim();
              break;
          case "float":
              objWriteVals = txtWriteDatas3.Text.Trim();
              break;
          case "bool":
              objWriteVals = txtWriteDatas4.Text.Trim();
              break;
      }
      //写入数量
      ushort writeCount = ushort.Parse(txtWPLCCount.Text.Trim());
      ushort objWCount = (ushort)objWriteVals.Split(',').Length;
      //实际数量与要求数量不一致，不允许操作
      if (writeCount != objWCount)
      {
          MessageBox.Show("写入值的数量不正确!");
          return;
      }
      List<string> vals = objWriteVals.Split(',').ToList();
      switch (dataType)
      {
          case "ushort":
              //实际数值转换成list集合ushort类型
              List<ushort> objushort = new List<ushort>();
              vals.ForEach((x) =>
              {
                  objushort.Add(ushort.Parse(x));
              });
              var finish1 = finsTcp.Write<ushort>(objushort, plcAddr);
              if (finish1.IsSuccessed)
              {
                  MessageBox.Show(finish1.Message);
              }
              break;
          case "short":
              //实际数值转换成list集合 short类型
              List<short> objshort = new List<short>();
              vals.ForEach((x) =>
              {
                  objshort.Add(short.Parse(x));
              });
              var finish2 = finsTcp.Write<short>(objshort, plcAddr);
              if (finish2.IsSuccessed)
              {
                  MessageBox.Show(finish2.Message);
              }
              break;
          case "float":
              //实际数值转换成list集合 float
              List<float> objfloat = new List<float>();
              vals.ForEach((x) =>
              {
                  objfloat.Add(float.Parse(x));
              });
              var finish3 = finsTcp.Write<float>(objfloat, plcAddr);
              if (finish3.IsSuccessed)
              {
                  MessageBox.Show(finish3.Message);
              }
              break;
          case "bool":
              //实际数值转换成list集合bool
              List<bool> objbool = new List<bool>();
              vals.ForEach((x) =>
              {
                  if (x == "1")
                  {
                      objbool.Add(true);
                  }
                  else
                  {
                      objbool.Add(false);
                  }
              });
              var finish4 = finsTcp.Write<bool>(objbool, plcAddr);
              if (finish4.IsSuccessed)
              {
                  MessageBox.Show(finish4.Message);
              }
              break;
      }
  }
