    1)功能(FC)是用户编写的程序块。功能是一种“不带内存”的逻辑块。属于FC的临时变量保存在本地数据堆栈中。执行FC时，该数据将丢失。为永久保存该数据，功能也可使用共享数据块。由于FC本身没有内存，因此，必须始终给它指定实际参数。不能给FC的本地数据分配初始值。

    2)FC里有一个局域变量表和块参数。局域变量表里有：IN（输入参数）、OUT（输出参数）、IN_OUT（输入/输出参数）、TEMP（临时数据）、RETURN（返回值RETVAL）。IN（输入参数）将数据传递到被调用的块中进行处理。OUT（输出参数）是将结果传递到调用的块中。IN_OUT（输入/输出参数）将数据传递到被调用的块中，在被调用的块中处理数据后，再将被调用的块中发送的结果存储在相同的变量中。TEMP（临时数据）是块的本地数据，并且在处理块时将其存储在本地数据堆栈。关闭并完成处理后，临时数据就变得不再可访问。RETURN包含返回值RET_VAL。

    2.功能(FC)的应用

    功能(FC)类似于C语言中的子程序，用户可以将具有相同控制过程的程序编写在FC中，然后在主程序OB1中调用。功能的应用并不复杂，先建立一个工程，再在管理器界面中选中“块”，接着单击菜单栏的“插入”→“S7块”→“功能”，即可插入一个空的功能。
