B15趋势视图
Trend（趋势）视图用于查看Exasmoc输入/输出数据的实际DCS趋势。此视图每页可以显示8笔，最多可显示40页。Pen Assignment Panel（笔分配面板）用于选择趋势数据。
由于Exasmoc控制器内部存储了所有趋势数据，即使它们未被选择，也可以在不丢失瞬时数据的情况下更改笔的分配。
趋势显示面板
prediction trend（预测趋势）用于绘制每个控制执行周期中SMOC控制器计算的时间序列中的预测值函数。可以通过将函数添加到现有的historical trend（历史趋势）面板的形式支持预测趋势。每个面板都可选择使用历史趋势或预测趋势。

B15. Trend View
Trend view is used to see actual DCS-like trends for Exasmoc input/output data. This view can display 8 pens per page and maximum of 40 pages can be displayed. Pen Assignment Panel is used to select the trend data.
As the Exasmoc controller stores all the trend data internally even if they are not selected, it is possible to change the pen assignment without loosing the transient data.
Trend Display Panel
The prediction trend is a function to graph the predicted values in the time series that the SMOC controller calculates each control execution period. The prediction trend is supported in the form of adding the function to the existing historical trend panel. Each panel is selectable for historical trend or prediction trend use.
