我的WINAC basicV4.1、STEP7 V5.4和一块CP5611卡安装在一台工控机上，为什么PC station无法下载。我在PG/PC 设置中也选中了PC internal方式，可怎么样也无法下载，总是提示“A station name has to be assigned in the component configurator for online connections via the PC-internal interface.
This name has to be identical with the name of the pc station which represents your programming device in the Step7 project.”这到底是怎么回事啊？
