(3) 时序流程图法：时序流程图法使首先画出控制系统的时序图（即到某一个时间应该进行哪项控制的控制时序图），再根据时序关系画出对应的控制任务的程序框图，zui后把程序框图写成 PLC 程序。时序流程图法很适合于以时间为基准的控制系统的编程方法。

(4) 步进顺控法：步进顺控法是在顺控指令的配合下设计复杂的控制程序。一般比较复杂的程序，都可以分成若干个功能比较简单的程序段，一个程序段可以看成整个控制过程中的一步。从整个角度去看，一个复杂系统的控制过程是由这样若干个步组成的。系统控制的任务实际上可以认为在不同时刻或者在不同进程中去完成对各个步的控制。为此，不少 PLC 生产厂家在自己的 PLC 中增加了步进顺控指令。在画完各个步进的状态流程图之后，可以利用步进顺控指令方便地编写控制程序。

2. 经验法编程

经验法是运用自己的或别人的经验进行设计。多数是设计前先选择与自己工艺要求相近的程序，把这些程序看成是自己的“试验程序”。结合自己工程的情况，对这些“试验程序”逐一修改，使之适合自己的工程要求。这里所说的经验，有的是来自自己的经验总结，有的可能是别人的设计经验，就需要日积月累，善于总结。

3. 计算机辅助设计编程

计算机辅助设计是通过 PLC 编程软件在计算机上进行程序设计、离线或在线编程、离线仿真和在线调试等等。使用编程软件可以十分方便地在计算机上离线或在线编程、在线调试，使用编程软件可以十分方便地在计算机上进行程序的存取、加密以及形成 EXE 运行文件。

7.3.2 PLC 软件系统设计的步骤

在了解了程序结构和编程方法的基础上，就要实际地编写 PLC 程序了。编写 PLC 程序和编写其他计算机程序一样，都需要经历如下过程。

1. 对系统任务分块

分块的目的就是把一个复杂的工程，分解成多个比较简单的小任务。这样就把一个复杂的大问题化为多个简单的小问题。这样可便于编制程序。

2. 编制控制系统的逻辑关系图

从逻辑关系图上，可以反应出某一逻辑关系的结果是什么，这一结果又英国导出哪些动作。这个逻辑关系可以是以各个控制活动顺序为基准，也可能是以整个活动的时间节拍为基准。逻辑关系图反映了控制过程中控制作用与被控对象的活动，也反应了输入与输出的关系。
