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

2.调用FBD编辑器

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

7.定义功能块参数
8.编译FBD程序
9.纠正语法错误

梯形图(LAD)也是1EC61131_ 3规定的一-种图形化组态语言,它起源于传统的由继电器线圈和触点
组成的反映逻辑电路电流状态的逻辑梯形图。梯形图的左右边界线分别称为供电母线和公共母线,梯
