The available security items are Screens: Allows users to enable or disable access to Screens. In an application, all users or groups have access to the main Screen, Alarms: Enables or disables alarm acknowledgment and removal of unbound alarms for a user or a group. In a project, users can display alarm information to several subscribers of that information by using a Screen object, such as an E3Alarm, Domains: Allows users to configure permissions to execute, stop, or edit a Domain, and remotely access a Domain, among other permissions, and Viewer: Allows users to use an Elipse Power Viewer in Viewer Control or Viewer Only mode, according to its settings |

Options for a list of permissions
Status |
Description |
---|---|
Allowed |
The selected command on this list of permissions is granted to the selected user or group, regardless of all groups to which they belong |
Not Allowed |
The selected command on this list of permissions is not granted to the selected user or group, regardless of all groups to which they belong |
Allowed by this Group |
The selected command on this list of permissions is granted to the selected user or group, if it is granted on groups to which the selected user or group belongs |
Not Allowed by this Group |
The selected command on this list of permissions is not granted to the selected user or group, if it is not granted to at least one of all groups to which the selected user or group belongs |
Not Informed |
The selected user or group uses all configurations from all groups to which they belong, and there is nothing informed on those groups. Therefore, the selected command is granted |
NOTE |
To configure all possible statuses for each security item on the permissions list, use the following options: •Right-click an item or use the shortcut key SHIFT + F10, which corresponds to the application or menu key •Double-click an item or use the space bar to toggle between Allowed, Not allowed, or Not informed statuses. |
For Screens, this configuration of permissions can be performed by Screen specifically. For Alarms, this configuration can be performed by Area.
NOTE |
In an application, all users have access to its initial Screen. In case users want that application to always start displaying a user login dialog box, create a user with no specific permission for its initial Screen. Thus, every time this application starts, it asks for a user login, and after that it displays its initial Screen. |
As for anonymous user permissions, users must notice the following situations:
•If there are no users at all, a permission check is not enabled, or there is no user with restrictions for a certain operation, then a user identification is not required, that is, users can log in as anonymous
•If there are users in an application, a permission check is enabled, and at least one user cannot execute a certain operation, then this operation requires a user identification, that is, users cannot log in as anonymous
NOTE |
Name and description of these restriction options can be viewed using the Legend option. |
In case there is any restriction to execute, stop, edit a Domain, or to configure users or groups, users must be logged in Elipse Power. To do so, use the Login or Logout options, available on the File menu.
User Login or Logout
The Login option opens a dialog box for logging in Elipse Power Studio. Users remain logged in until another login or logout is performed.
The Logout option executes a log out from Elipse Power Studio. In case no user is logged in, this option is then disabled.
