斑竹：我新建了一个项目 可以组态 但是组态结束以后 退出来 再进去 就出现no changes can be made in the station ？？这样是不是s7出了问题呢
我看了help！
To Correct or Avoid Error:

?Open the offline configuration of the station (menu command Station > Open Offline) or

?Copy the project to a directory to which you can write or

?Install the necessary optional package or the later version of STEP 7 necessary to edit or configure the station.

怎样看一个项目是不是 写保护的呀？
