6.2 What You Should Know About Access Protection
As of STEP 7 V5.4, you have the option of restricting access to projects and libraries by assigning
a project password. This functionality is available only if SIMATIC Logon is installed.
You can also enable, disable and display a change log.
If SIMATIC Logon is installed on your computer, the following dynamic menu commands are
available in the SIMATIC Manager. You can use these commands to manage access protection for
a project or library:
• Access Protection, Enable
• Access Protection, Disable
• Access Protection, Manage
• Access Protection, Adjust in Multiproject
• Remove Access Protection and Change Log
You activate access protection in SIMATIC Manager with the menu command Options > Access
Protection > Enable. If you enable access protection for the first time with this menu command, a
dialog opens in which you will need to log on with SIMATIC Logon. You will then be prompted to
assign a project password. The relevant project or library can then only be edited by an
authenticated user or after entering the project password.
The Remove Access Protection and Change Log menu command removes access protection
as well as the change log for a password-protected project or library. After removing the access
protection, you can once again edit projects with a STEP 7 version prior to V5.4.
