上节开发了一个winform版的通讯测试工具这节再搞个wpf版的wpf是什么请自行百度也可以看前面的博客WPF真入门教程wpf的界面效果是比winform漂亮因为wpf使用了web项目中的css样式来美化界面在这个例子中用到wpf的控件资源样式命令绑定等采用的是mvvm的渲染模式界面如图 前面的winform界面 2、开工干
2.1 创建wpf项目 2.2 创建目录及PLC模型类对象 2.3 创建自定义的消息弹窗 MsgBoxWindow.xaml代码

/Window运行起来效果 3、测试软件
3.1 测试PLC连接 3.2 读取dm区100的short类型 3.3 读取h区100的ushort类型 3.4 读取w区100的float类型 3.5 读取cio区100的bool类型 3.6 写入DM区110的short类型 3.7 写入H区110的ushort类型 3.8 写入W区110的float类型 3.9 写入CIO区110的bool类型 全部通讯报文 4、小结
本例子用到WPF的MVVM模式不是winform中的按钮点击事件是后台绑定viewmodel用数据驱动页面控件跟vue中的mvvm渲染数据方式一样跟微信小程序的MVVM模式一样的这就实现了界面与数据的分离。
