Password security
Note
Assigning secure passwords
Observe the following rules when assigning new passwords:
● When assigning new passwords, never choose passwords that can be easily guessed, e.g.
simple words, sequences of consecutive keys on the keyboard, etc.
● Passwords must always contain a combination of upper-case and lower-case letters as well
as numbers and special characters. Passwords must comprise at least 8 characters. PINS
must comprise an arbitrary sequence of digits.
● Wherever possible and where it is supported by the IT systems and the software, a
password must always have a character sequence as complex as possible. You can use a
password management program to assist you when dealing with passwords. With its help,
you can save passwords and PINs in encrypted form, manage them and generate secure
passwords.
Note
Changing passwords between SINUMERIK Commissioning and NC
The access levels for SINUMERIK Commissioning and the NC have been merged. If you
change a password for SINUMERIK Operate, this simultaneously changes the corresponding
NC password and vice versa. It is important to note the following behavior:
● When a general NC reset is performed, no passwords are reset to the default passwords.
● Following a software upgrade, the SINUMERIK Commissioning passwords apply to the NC.
● Once changed, a password can no longer be reset - not even by SIEMENS service.
Therefore, make sure that you store the changed password in a safe place.
Set password
Procedure:
1. Open the application SINUMERIK Commissioning.
2. Select the "Commissioning" operating area and press the "Password" softkey.
