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 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 References 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. If the status for the data point displays General Access Denied, the data point is inaccessible and therefore not readable for COV subscriptions.
