只有在执行该POU时，定义的临时变量才被使用，POU执行完后，不再保存临时变量的数值。2)IN是由调用它的POU提供的输入参数。3)OUT是返回给调用它的POU的输出参数(子程序的执行结果)。4)IN_OUT是输入_输出参数，其初始值由调用它的POU传送给子程序，并用同一变量将子程序的执行结果返回给调用它的POU。主程序和中断程序的局部变量中只有临时变量TEMP。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。

　　电缆额定电压的选择●电缆的额定电压应适合于电缆系统的运行状况，用Uo/U（Um）KV表示。Uo--电缆设计用的导体对地或金属屏蔽之间的额定工频电压；U--电缆设计用的导体间的额定工频电压；Um--设备可承受的“高系统电压”的大值。
