C#上位机与三菱PLC的通信11---开发自己的通讯工具软件(WPF版)

1、先看颜值

2、开始干

1、创建项目

2、引入前面的通讯库

创建目录将前面生成的通讯库dll文件复制到项目的目录

本项目引入dll文件

3、创建命令基类

RelayCommand.cs代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Input;

namespace MitsubishiMcToolWPF.Common
{
    /// <summary>
    /// 命令实现类
    /// </summary>
    public class RelayCommand : ICommand
    {
        public event EventHandler CanExecuteChanged;
        /// <summary>
        /// 要执行的操作
        /// </summary>
        private Action<object> executeActions;
        /// <summary>
        /// 是否可以执行的委托
        /// </summary>
        private Func<object, bool> canExecuteFunc;
        /// <summary>
        /// 构造函数 无参构造
        /// </summary>
        public RelayCommand() { }
        /// <summary>
        /// 通过执行的委托构造
        /// </summary>
        /// <param name="execute"></param>
        public RelayCommand(Action<object> execute) : this(execute, null)
        {

        }
        /// <summary>
        /// 通过执行的操作与是否可执行的委托
        /// </summary>
        /// <param name="execute">要执行的操作</param>
        /// <param name="canExecute">是否可以被执行</param>
        public RelayCommand(Action<object> execute, Func<object, bool> canExecute)
        {
            this.executeActions = execute;
            this.canExecuteFunc = canExecute;
        }

        /// <summary>
        /// 命令是否可以执行
        /// </summary>
        /// <param name="parameter"></param>
        /// <returns></returns>
        public bool CanExecute(object parameter)
        {
            if (canExecuteFunc != null)
                return this.canExecuteFunc(parameter);
            else
                return true;
        }

        /// <summary>
        /// 要执行的操作
        /// </summary>
        /// <param name="parameter"></param>
        public void Execute(object parameter)
        {
            if (executeActions == null)
                return;
            this.executeActions(parameter);
        }

        /// <summary>
        /// 执行CanExecuteChanged事件
        /// </summary>
        public void OnCanExecuteChanged()
        {
            this.CanExecuteChanged?.Invoke(this, new EventArgs());
        }
    }
}

4、创建PLC实体类

PLCMemoryModel.cs代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MitsubishiMcToolWPF.Model
{
    /// <summary>
    /// PLC内存模型类
    /// </summary>
    public class PLCMemoryModel
    {
        /// <summary>
        /// 存储区
        /// </summary>
        public string Area { get; set; } = "";
        /// <summary>
        /// 地址
        /// </summary>

        public string Address { get; set; } = "";
        /// <summary>
        /// 数据类型
        /// </summary>

        public string DataType { get; set; } = "";
        /// <summary>
        /// 读取或写入数据
        /// </summary>

        public string Count { get; set; } = "";
    }
}

5、添加资源字典，即样式文件

CommonResource.xaml完整代码

 <!--读取写入Button按钮样式--> 
 <Style x:Key="ButtonStyle" TargetType="Button">
     <Setter Property="Background" Value="#3F85FF"></Setter>

 </Style>

6、创建viewmodel

viewmodel是视图模型，wpf采用的是mvvm的渲染模式，即控件绑定对象的属性，属性发生更改时，驱动控件的数据显示，而控件动作是由命令command执行

1、模型基类

ViewModelBase.cs代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Runtime.CompilerServices;
using System.Text;
using System.Threading.Tasks;
using static MitsubishiMcToolWPF.MsgBoxWindow;

namespace MitsubishiMcToolWPF.ViewModel
{
    /// <summary>
    /// 视图模型基类
    /// </summary>
    public class ViewModelBase : INotifyPropertyChanged
    {
        /// <summary>
        /// 属性值发生更改时触发
        /// </summary>
        public event PropertyChangedEventHandler PropertyChanged;



        /// <summary>
        /// 执行更改
        /// C#5.0中的新特性CallerMemberName
        /// </summary>
        /// <param name="propertyName"></param>
        protected void OnPropertyChanged([CallerMemberName] string propertyName = "")
        {
            if (PropertyChanged != null)
            {
                PropertyChanged.Invoke(this, new PropertyChangedEventArgs(propertyName));
            }
        }


        /// <summary>
        /// 成功消息提示
        /// </summary>
        /// <param name="message"></param>
        /// <param name="title"></param>
        /// <param name="buttons"></param>
        public void ShowMessage(string message, string title = "提示", CustomMessageBoxButton buttons = CustomMessageBoxButton.OK)
        {
            Show(message, title, buttons, CustomMessageBoxIcon.Infomation);
        }

        /// <summary>
        /// 错误消息框
        /// </summary>
        /// <param name="message"></param>
        /// <param name="title"></param>
        /// <param name="buttons"></param>
        public void ShowError(string message, string title = "错误", CustomMessageBoxButton buttons = CustomMessageBoxButton.OK)
        {
            Show(message, title, buttons, CustomMessageBoxIcon.Error);
        }

        /// <summary>
        /// 询问消息框
        /// </summary>
        /// <param name="message"></param>
        /// <param name="title"></param>
        /// <param name="buttons"></param>
        /// <returns></returns>
        public CustomMessageBoxResult ShowQuestion(string message, string title = "询问", CustomMessageBoxButton buttons = CustomMessageBoxButton.OKCancel)
        {
            return Show(message, title, buttons, CustomMessageBoxIcon.Question);
        }



    }
}

2、主页模型mainviewmodel

MainViewModel.cs代码

using Mitsubishi.Communication.MC.Mitsubishi;
using MitsubishiMcToolWPF.Common;
using MitsubishiMcToolWPF.Model;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Input;

namespace MitsubishiMcToolWPF.ViewModel
{
    /// <summary>
    /// 视图模型
    /// </summary>
    public class MainViewModel : ViewModelBase
    {
        /// <summary>
        /// mctcp对象
        /// </summary>
        A3E mctcp;

        #region 属性

        PLCMemoryModel readPLCModel = SetInitModel();
        /// <summary>
        /// 读取PLC
        /// </summary>
        public PLCMemoryModel ReadPLCModel
        {
            get { return readPLCModel; }
            set
            {
                readPLCModel = ReadPLCModel;
                OnPropertyChanged();//属性通知
            }
        }

        PLCMemoryModel writePLCModel = SetInitModel();
        /// <summary>
        /// 写入PLC
        /// </summary>
        public PLCMemoryModel WritePLCModel
        {
            get { return writePLCModel; }
            set
            {
                writePLCModel = WritePLCModel;
                OnPropertyChanged();
            }
        }
        /// <summary>
        /// 初始化页面参数
        /// </summary>
        /// <returns></returns>
        private static PLCMemoryModel SetInitModel()
        {
            PLCMemoryModel model = new PLCMemoryModel();
            model.Area = "D";
            model.DataType = "short";
            model.Address = "100";
            model.Count = "1";
            return model;
        }

        private string hostName = "192.168.1.7";
        /// <summary>
        /// PLC地址
        /// </summary>
        public string HostName
        {
            get
            {

            }
            set
            {

            }
        }

        private string hostPort = "6000";
        /// <summary>

            }
        }

            }
        }

        private string readWords = "";

8、启动MC服务器

9、异常错误处理

10、操作测试

1、连接PLC

2、读取数据，short,float,bool

3、写入数据，short,float

写入short

写入float

3、小结
