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PLCif (!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 floatList<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boolList<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;}}
最后看下报文
3、小结
通讯库100%正确,实现了bool,ushort,short,float类型数据的读取和写入,可以看到封装得超爽,有这个工具,到项目开发中就可以用得上这个工具软件,用来调试测试PLC程序,打通与电气工程师的通讯数据,超强啊。
