Viewer Groups Tab |
Users can specify, according to Elipse Power Viewer's IP address, if it can connect, and with which license type, Viewer Control or Viewer Only.
With this resource, users can completely block a connection, or limit the number and type of licenses to use simultaneously by a certain group of IP addresses.
To access groups of Elipse Power Viewers, right-click the E3 Admin icon on Windows Notification Area, select the Domain - Options option to open the window on the next figure, and then click Viewer groups tab.
Viewer groups tab
The available options on this tab are described on the next table.
Available options on the Viewer groups tab
Option |
Description |
---|---|
Name |
Lists names for all groups of Elipse Power Viewers |
Add and Remove |
Adds or removes groups of Elipse Power Viewers |
Group name |
Enables creating or changing the names of groups of Elipse Power Viewers |
IP list |
Specifies which IP addresses belong to a group, and thus share the same connection limits. When an Elipse Power Viewer tries to connect to an E3 Server, its IP address is compared to the existing groups. After determining to which group it belongs, a license restriction is applied to this Elipse Power Viewer, configured to that group |
Add, Edit, and Remove |
Adds, edits, or removes IP addresses. When a group is created, it contains no specified IP address, except for the first group, which is always *.*.*.* and cannot be created by a user. If users try to save these settings, and a group contains an empty list of IP addresses, Elipse Power Studio then displays a warning message. If this group is kept that way, it is useless |
Allow Viewer Control connections |
When selected, it allows Viewer Control-type connections for this group |
Limit simultaneous license use |
When selected, it limits using simultaneous Viewer Control-type licenses down to a certain number. If the previous option is selected, but this one is not selected, using simultaneous licenses is unlimited |
Allow Viewer Only connections |
When selected, it allows Viewer Only-type connections for this group |
Limit simultaneous license use |
When selected, it limits using simultaneous Viewer Only-type licenses down to a certain number. If the previous option is selected, but this one is not selected, using simultaneous licenses is unlimited |
Users must notice that these limits are applied after E3 Server's limit, as configured on the protection device. For example, if a protection device contains ten Elipse Power Viewer licenses and a group specifies a maximum of five connections, only these five connections are used. However, if a protection device contains five Elipse Power Viewer licenses and a group specifies a maximum of ten connections, the limit of five connections on the protection device is used. That is, an Elipse Power Viewer group always has an additional limitation of licenses to apply during Elipse Power Viewer's connection.
Elipse Power Viewer group configurations must be performed preferably when a Domain is stopped. If they are performed while a Domain is executing, they are not effective until all Elipse Power Viewers are disconnected.
NOTES |
For connections identified as E3AccessLayer and E3DataAccess, which by default do not consume licenses from an E3 Server, Elipse Power Viewer groups' behavior is the following: •If a group of Elipse Power Viewers does not allow Viewer Control- nor Viewer Only-type connections, then connection is denied •If a group of Elipse Power Viewers allows Viewer Control-type connections, then connection is allowed and obeys the requested access type. For example, for Viewer Only-types a connection is read-only, and for Viewer Control-types a connection is for reading and writing •If a group of Elipse Power Viewers allows only Viewer Only-type connections, then connection is allowed and read-only, even for Viewer Control-type connections |
