"User management" parameter group
Meaning of user management
In user management, you specify which users have which permissions when accessing the
S7 station.
In the alphabetical list, you will find the users that have already been entered under user
name for which passwords have been stored.
The "Everybody" entry is a default entry and is always present. This cannot be modified. It is
also not possible to assign a password to this entry.
User entries are always linked to a password. Exception: The "Everybody" entry is not
password protected.
Note
As default, no permissions whatsoe
ver are assigned under the "Everybody" entry. For
service purposes, however, it is possible to assign permissions.
You should, however, remember that any permissions assigned to the "Everybody" user are
also available to every other user. If you do assign
permissions for service purposes,
remember to cancel these again afterwards! Otherwise, you allow services to be executed
without authorization with every access.
If an access right is set for "Everybody" users, the corresponding check boxes are selected
and visible when you assign permissions to other users.
Security enabled
In security user management, you can create users, roles and rights (configuration- and
module-specific).
3.3.9
"Symbols / Tag declaration" parameter group
Meaning of the tag declaration
To access tags of the CPU using a Web browser and Java applet, the CP must be aware of
the names, addresses, and access rights of these tags.
The tags defined for the CPU are shown in a list. From this list, you select the tags
accessible for Web access.
Assigning access rights
As default, only read-only rights are assigned for the tags. Where necessary, assign write
permissions.
