5．S7-300/400与IEC61131-3程序结构的区别
1）S7-300/400的功能可以有多个输出参数，返回值也属于输出参数。IEC61131-3的功能只有一个返回值。
2）IEC61131-3的功能块用于保存局部变量的**存储区是在声明功能块的实例时分配的，它对用户是不透明的，其他POU不能直接访问该存储区。
S7-300/400的功能块的局部变量（不包括临时变量）保存在它的背景数据块中。其他POU可以访问背景数据块中的变量。如果需要多次调用同一个功能块来控制同一类型的被控对象，每次调用都需要一个背景数据块，但是这些背景数据块中的变量又很少，这样在项目中就出现了大量的背景数据块。可以使用多重背景数据块来减少背景数据块的数量。但是需要增加一个用来管理多重背景的功能块。
3）S7-300/400的功能块的局部变量有临时变量和静态变量，IEC61131-3的功能块的内部变量Var相当于S7-300/400的静态变量。
4）S7-300/400将数据区划分为数据块来使用，数据块的大小与数据块中定义的变量的数据类型和变量的个数有关。IEC61131-3没有数据块的概念。
