接口等组态)、工程调试和诊断功能为- -体的工具软件包。CBF采用统- -的 系统全局数据库和强大的交
叉参考工具,不仅能方便地完成自动化组态,而且是一个高性能的过程调试工具。Industrial”DCS系
统过程控制站PS所需的各种控制算法和策略都是由CBF来组态的,井采用图形化的组态方法(符合
1EC61131- 3标准)。
CBF也用于对操作站人机接口(HIS)功能的组态并还可直接对现场总线设备进行组态。
控制算法和策略组态可选用以下IEC 61131-3标准组态方法中的一-种或几种:
FBD (功能方块图 )
JD (梯形图)
SFC (顺序功能图 )
IL (指令表)
sT (结构化文本)
CBF安装在Industrial “系统工程师站上,完成后的组态结果由工程师站通过系统网络下载至相应
的现场控制器PS及操作站0S中。组态既可在线也可离线。离线组态仅需-台装有CBF软件的计算机。
系统提供-一个含有220多种功能模块(标准算法程序)的功能块库,除了IEC 61131 _3 标准规定
的基本内容外,还扩充了许多功能强大并经过严格测试的功能块。用户还可自定义功能块和由若千功
能块组成的用户宏。CBF 还提供200 多个标准图形符号(静态和动态)及大量美观实用的立体图例可
供HIS组态选用。
CBF在执行组态编译时能自动查找定位错误源,交叉参考功能可帮助工程师迅速查找对应的变
量位号、功能块及操作画面,大大提高了组态效率。CBF可引入或导出ASCII 程序、显示画面、变
量位号和部分项目树。CONTROL BUILDER F还可输出包括全部组态结果的图形化工程文档。

控制策略自动化功能组态方式
控制鐐略组态方法功能块圜(FBD)
功能块图(FBD)是- -种图形化组态编程语言,用于实现回路调节
控制和逻辑控制功能。FBD 程序是由若干功能块图有机排列而成,
各种功能、功能块及程序输入输出变量之间用信号流向线按照控制
逻辑进行连接。控制某过程所需的信号处理由FED程序完成。由于具备CAD功能,因此可以在图形工
作区轻松实现各功能和功能块的定位及连接。FBD 编辑器的输入输出区用来键入输入输出变量,输入
在左,输出在右,信号流向由左至右。从功能块引脚和信号线的版面形式(粗细、颜色等)可以知道数
据类型。功能块参数定义的方法是在FBD参数对话框中行进行填空。完成后的FBD程序需经编译,检
查错误和语法。查出的错误或警告以列表显示,用鼠标单击表中某–行可直接转到相应的出错源址。
利用交叉参考功能,可迅速调出与错误对应的显示画面和程序并容易地找到相关变量和回路。
FRD的组态步骤如下:
1.定义FBD程序名称
5
2.调用FBD编辑器
功能&功能块
3.选择所需功能或功能块
4.将功能块放置在图形工作区
5.用信号流向线连接各功能块
6.键入输入输出变量
7.定义功能块参数
8.编译FBD程序
9.纠正语法错误
