When I was debugging, I ran into a confusing problem.
When I edited the plantform, the IDE indicated that the modification was successful, but when I viewed the plantform, the modification did not take effect.
On this computer, I was able to complete the debugging of 6678 through CCS IDE, which means that all functions of CCS are normal except that plantform cannot be modified.
But the plantform was successfully modified when I used another computer.
I think it could be a software configuration problem. Because in the previous, due to a misoperation to format the CCS installed disk, it is not a regular uninstall.
I look forward to your help.
