SFC编程又被称为顺序功能图编程,它是根据国际电工委员会IEC标准化的一种图形编程语言,其标准编号为IEC 61131-3。SFC的特点在于通过顺序步骤(Steps)和转换(Transitions)的方式,将复杂的控制流程分解成易于管理的单元。每个步骤可能包含一个或多个动作,而转换则决定何时步骤应该结束,并触发下一个步骤的开始。这种方法非...
SFC编程的核心是其直观的图形表示,它允许开发者通过顺序图的形式直接构建程序逻辑。每个顺序图包含多个步骤(Steps)、转移(Transitions)和动作(Actions),通过这些元素的有机组合来实现程序控制流的设计与实现。 二、步骤与动作 在SFC编程中,步骤是基本的执行单元,可以看作是程序中的一个状态或阶段。每个步骤可以关联一...
Clear the SFC step status of one or more routing steps, as though a SFC number was never worked on at the routing step Mark routing steps as bypassed You can also view information about the SFC numbers in the SFC report Note You cannot change status of SFC number, if it is a member ...
SFC图形由一个或多个连续的步骤(steps)组成,每个步骤代表一个特定的状态或操作。步骤之间通过转变(transition)连接,转变表示系统从一个状态转换到另一个状态的触发条件。 SFC类型中的组态概念是指使用SFC图形来描述和定义系统的状态和控制流程。组态是系统集成和配置工程师在系统设计和实施过程中创建的一个图形界面,用...
4)Transition 1:等待开关14接通。 5)Step 2:打开4号灯。 6)Transition 2:等待开关15接通。 7)Step 3:关闭4号灯。 8)Transition 3:始终为真,所以没有等待 刚刚添加了Action,因此现在需要编写让2号灯和3号灯打开的代码。 10.双击“操作”(Action)框中的问号,并按如图14-7所示输入逻辑。
