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)。
操作站及工程师站硬件均为标准的PC机(通用型或工业加强型甚至是便携机),采用微软公司
Windows 2000操作系统(中英文版均可)。因此PC机的配置水平与PC市场主流配置及最新的技术发
展保持同步并可根据用户要求确定。
