IC200UDR440UB2电路板通讯
具有输入、输出参数和局部变量的子程序易于实现结构化编程，对于长期生产同类设备或生产线的厂家尤为有用。这些厂家的编程人员为设备的各组件或工艺功能编写了大量的通用的子程序。即使不知道子程序的内部代码，只要知道子程序的功能和输入、输出参数的意义，就可以通序之间的调用快速“组装”出不同用户要求的控制程序。就好像用数字集成电路芯片组成复杂的数字电路一样。子程序如果没有输入、输出参数，它和调用它的程序之间没有清晰的接口，很难实现结构化编程。子程序如果没有局部变量，它和调用它的程序之间只能通过全局变量来交换数据，子程序内部也只能使用全局变量。将子程序和中断程序移植到别的项目时，需要重新统一安排它们使用的全局变量，以不会出现地址冲突。当程序很复杂，子程序和中断程序很多时，这种重新分配地址的工作量非常大。如程序和中断程序有局部变量，并且它们内部只使用局部变量，不使用全局变量，因为与其他POU没有地址冲突，不需作任何改动，就可以将子程序移植到别的项目中去。
