When I try to download it asks to login (see picture). If I login with what should be the right password it keeps saying that it's the wrong password. Is there a way that I can see what password is the right one? If not is there a way that I can download the hardware config without the password? And if that is not possible is there a way to do a factory reset that doesn't require the password?

If there is still an old project on the CPU, then of course you need the password for the old project. Here is a thread on this topic: https://sieportal.siemens.com/de-de/support/forum/posts/programm-nderung-in-einer-s7-1x00-steuerung-passwort-vergessen-was-nun/309314?page=0&pageSize=10 The thread is in German. Here is another link for the factory reset: Resetting the CPU to factory settings Best regards
