有个用Ｖ6.2中文版版做的程序，但现要用Ｖ7.1英文版的来修改，结果打开修改都正常，但是编译就是不通过，提示有个错误，W: SIMATIC 400(1) (---) is not supported.
E: Necessary files are missing for block CH_AI. Please note that you have to install exactly the same version of the library as the one this block was imported from..这个6.2版做的项目如何升迁到Ｖ7.1解决这个问题呢？先谢谢了！
