WinCC中基于C脚本和OCX的数据搜索方法

The method to realize data-searching by using C-Script and OCX based on WinCC

为了解决WinCC中查询历史数据难以确定具体时间范围的问题,本文提出了利用产品信息搜索实现数据快速查询的方法。利用C-Script将与产品相关的的时间信息写入文件,通过产品编号搜索,从文件中读出相应的信息并显示在ListView控件中。点击显示在ListView中的某产品信息所在的行,就可以将与该产品相关的数据显示在WinCC在线趋势或在线表格中。

Since it is difficult to fix a specific time range in historical data inquiry in Wi＇nCC , this paper brings forward a new method of quick data-searching by means of product-information-searching. With the help of C-Script, we can write in the document the time information related to the product. By looking up the serial number of the product, we can read the relevant information shown in the ListView control. These detailed data of the product will be demonstrated in WinCC Online Trend or WinCC Online Table if we click the line where the product information is displayed in ListView.
