I was completely locked out of my own safety program on an S7-1500 and couldn't access my safety blocks and wasn't able to compile it.
After spending way too much time in digging , I finally managed to remove the password safely—without corrupting or losing any project data.
Now I can modify my safety blocks and recompile it.
Now I can edit my safety blocks again. If you're in the same situation, I can help you regain access too.
