CPU passwords
If a CPU is password protected, this password must be entered in the SIMATIC Automation
Tool to complete many operations. You provide the password in the main grid column titled
Password.
The SIMATIC Automation Tool prevents you from legitimating a connection to a fail-safe
CPU using the fail-safe password. For this reason, whenever you enter a password (in the
"Password" column of the main grid) for a fail-safe CPU, a message box is displayed that
warns you not to use a fail-safe password.
If you ignore this warning (or did not know you used the fail-safe password) and enter the
fail-safe password anyway, the legitimation is rejected and your entry is deleted from the
password field.
