工艺过程状态的显示画
面,工艺流程画面是典型的自由图形显示。
在自由图形中,当前的过程数据或过程状态可以数字或模拟形式进行显示(如棒图、动态填充或
趋势窗口) .画面显示中的图形符号可根据过程状态进行置换、闪烁、变色以及位置变化,即进行动
态显示。所选择的过程变量可通过流程画面中的面板或通过标准分组画面进行显示操作。
如果组态了画面调用热区或调用按钮,则可在自由画面中设置指定的画面调用体系,它确定彼此

趋势显示和归档
模拟和数字过程变量随时间的变化过程可以趋势画面进行显示并归档存储。ABB Industial”DCS
控制系统的实时趋势显示和历史趋势显示没有限制。
在一个趋势画面中可显示以下内容:
● 最多6个不同颜色的趋势曲线
●带简短注释的相应测量点名称
当前测量点值及其量程和单位
趋势显示可进行如下改变:
●移动时间轴以显示过去值
●暂时取消趋势曲线
●移动和缩放显示画面
●对每 个趋势进行的特殊设定(如颜色、插入值)
●选择不同的时间刻度 范围(从秒到周)
