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。
硬件结构
所需硬件及系统通信可在硬件编辑器(画面)中定义配置,并可得到操作站、过程站/现场控制器及
相应模件的详细信息。在站结构显示画面中,通过下拉式选择表完成操作站、过程站/现场控制器的
配置组态。每个过程站/现场控制器件处理显示规格及1/0 通道或通信接口的分配可分别组态。在硬
件编辑器中还可定义配置现场总线设备。
