蒙圈了！ 做了一个项目用到西门子的TP177B的触摸屏，挂DP总线，在组态和调机的时候，在Hardware里将屏挂到DP总线时下方的属性对话框里有两层小格，我将模块型号拖放进去时显示两层均可安置，但不知另一层作何用？如果在此窗口直接编译保存则无错误，但返回到工程根目录编译保存“Profibus”时则会有以下错误信息（下载后程序能使用），求高手赐教！ “Warning: Caution: in station PressHMI there are additional nodes that also have to be reloaded.” “Warning: Caution: in station TrimHMI there are additional nodes that also have to be reloaded.” Error: An error occurred creating or interpreting the system SDB.
