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
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
控制策略组态方法_顺序功能圉(SPC)
利用顺序功能图SFC可以方便地生成清晰的、图形化的顺序控制程序。要建立- -个SFC,需组态
要被执行的任务(命令)步(step)和允许执行下-步的步进条件(transition),并为步和步进条件分配
功能块图、指令表或梯形图程序.顺序功能图的另-特性是能够产生选择性或并列性分支及对顺序结
构进行同步。完成一个顺序功能图(SFC)控制程序组态的同时,也自动生成- -个用于操作站上显示的
SFC画面。
控制策略组态方法_指令衰(IL)
指令表与计算机汇编语言比较类似,系统所有的过程处理功能均可由指令表编程实现.它能实现
诸如程序跳转和循环等FBD、LAD 及SFC所无法实现的功能。操作符可被显示和键入,并提供一个符
合IEC61131 3标准的带有下拉条的操作符列表框供直接输入。指令表中也可调用功能块和FBD图中
的其它操作,功能块参数定义方法与在FBD中完全-样。

控制鐐略組态方法_梯形图(LD )
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
级由链接线、触点和线圈等梯形图元素构成。梯形图中同样也可调用功能块,功能块参数定义方法与
FRD中完全-样。梯形图最适于组态逻辑控制功能。

The engineering application software cost of the automation project accounts for about the entire project.
About 50%, it is not difficult to see that the migration of cost structure creates a lot of innovation for users.
Create an opportunity to optimize project investment, therefore, it is necessary to start from engineering programming
Think about lowering costs in the first place!
This is what we developed the Freelance 800F system for:
Keeping hardware prices consistent with those of programmable logic controllers
In this way, cost efficiency can be improved by reducing user engineering costs.
