DigiVis软件有如下特性:
o
系统信息的层次化分布使操作清楚迅速
o
变量的直接快速搜索
采用统- – 信息概念、清晰的信息显示和操作员提示
DigiVis图形显示种类包括自由图形显示(工艺流程等)及大量标准显示，下面将 分别介绍:
自由圜形显示
自由图形显示是按照裴置工艺和操作员的专门需要进行组态的，用以表示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換、闪烁、变色以及位置变化，即进行动
操作管理级主要包括操作站、工程师站、数据网关、管理计算机及相应软件，另外还包括打印
机、操作台等辅助设备。操作站的任务是生产监控，即综合监视来自过程控制级的所有信息，进行监
示、报警、趋势生成、记录、打印输出及人工千预操作(发送命令、修改参数等)。工程师站用于系
统软件组态和调试投运，它无需永久性接入系统，操作站也可兼作工程师站(需按工程师权限登
录)。

S800 and S900 are distributed i/0 for process control stations. They communicate with their controllers through Prof ibusdp Fieldbus
Communication, which can be installed in the controland PA three levels, DP communication rate can be as high as 12Mb. The CAN (DIN/IS011898 standard) bus
The biggest feature is its super sturdiness and data security. The system of course also supports Modbus. The communication with the intelligent field instrument is through
IART protocol or field bus (31. 25Kb ProfibusPA and FF bus).
The system communication between the operation management level and the process control level is realized by Di
