6.2 What You Should Know About Access Protection
Programming with STEP 7
Manual, 05/2010, A5E02789666-01 157
Note
• To disable access protection, you must be authorized in SIMATIC Logon as project administrator.
• The first time you enable access protection, the project format is changed. You will receive a
message indicating that the modified project can no longer be edited with older STEP 7 versions.
• The Options > Access Protection >Remove Access Protection and Change Log function
allows the project or the library to be used with a STEP 7 version lower than V5.4. You do,
however, lose the information on the users that are allowed access to this project or library and all
change logs.
• The user currently logged on is displayed in the status bar of the SIMATIC Manager.
• The currently logged on Logon user who enables access protection is entered as the project
administrator and is requested to assign the project password the first time access protection is
enabled.
• To open an access protected project, you must be authenticated in SIMATIC Logon as project
administrator or project user or you must know the password.
• Remember that a logged-on user is entered in the project as project administrator when a project
is opened with the project password.
• If the project/library access protection is active, the icon has a red key. If the multiproject only
contains projects/libraries with active access protection, the icon also has a red key.
• If the project/library access protection is disabled, the icon has a white key. If the multiproject
contains projects/libraries both with active and deactivated access protection or projects/libraries
with deactivated access protection, the icon is also displayed with a white key.
