(?) That seems very strange. Could you show a screen capture so that we can be 100% sure where it asks this.

Try "logo" or "LOGO".

 Thank you, it was LOGO

it is incredible: Siemens deliver new items a not a piece of paper or instruction to tell you the dafault password.

thanks again

You can download the user manual for Siemens logo. There, the password is described with access protection for the menus.

Chapter 3.5.
