4.1.7 Scopes and Data Point Access
Assigning Scopes to Graphic Objects
Scope is a grouping of system objects, or nodes with specific scope definitions
used for the purpose of assigning access rights. You can create scopes and assign
access rights to any of the graphic nodes in the Graphics system tree. For more
information, see Scopes.
You can apply scopes to the following graphic nodes:
 Graphics
 Symbols
 Templates
 Manual and Automatic Pages
Data Point Access Privileges
Data points are integrated into a graphic by associating them with elements. These
data points and elements can be evaluated by creating expressions that result in a
graphic that allows you to view dynamic values of a facility, building, or piece of
equipment. Data points, therefore, always display using the elements they are
associated with.
Depending on the your access rights, which are set in the System Manager, certain
data points can be inaccessible. In this case, if one or more data points associated
with an element is inaccessible, then the associated element will not display in the
graphic while in Runtime mode or in the Graphics Viewer. However, the parent of
an element, such as a Symbol instance or a group, and any other associated
children (elements), are not affected and will display on the graphic. This is
considered the
Hide-Rule for data points in a graphic.
The Hide-Rule does not apply to Object References and Link Reference since
there are no COV subscriptions involved in these scenarios.
When a data point with an existing address is subscribed for COV’s, the data
point’s status and value are updated automatically in the Value Simulator view. If
the Status for the data point displays, General AccessDenied, this indicates
that the data point is inaccessible and therefore not readable for COV
subscriptions.
