3．西门子的S7-300/400的程序结构
S7-300/400将子程序分为功能（Function，或称为函数）和功能块（FunctionBlock）。
S7-300/400的功能与S7-200的子程序基本上相同。它们均有输入、输出参数和临时变量，功能的局部数据中的返回值实际上属于输出参数。它们没有的存储区，功能执行结束后，不再保存临时变量中的数据。
可以用全局变量来保存那些在功能执行结束后需要保存的数据，但是会影响到功能的可移植性。
功能块是用户编写的有自己的存储区（即背景数据块）的程序块，功能块的输入、输出参数和静态变量存放在的背景数据块中，临时变量存储在局部数据堆栈中。每次调用功能块时，都要一个背景数据块。功能块执行完后，背景数据块中的数据不会丢失，但是不会保存局部数据堆栈中的数据。
