DataTree_ControlArea is a project designed to demonstrate how to use the Data Tree component for the visualization of the control area tree structure. Tags of all basic data types listed in the tree structure (the Tags subtree) are defined within the System device. Two data tables are defined via the Data Table Manager to log the System device's tags. Two trends and two reports are also defined via the Trend Manager and the Report Manager to visualize historical data. In addition, actions to display current and historical alarms/events, tables, and trends are defined via the Action Manager. These actions are connected to the data tree nodes. The Data Tree component's structure simulates the structure of the control area.

The Display cell is used to view the tag parameters (the Tags subtree). At runtime, you can also edit tag values using the displays located to the right of the tree. To activate commands or change the structure of the Data Tree component, it is required to log on. If you log on as the Edit user, you are allowed to edit the Data Tree structure (no password is required). If you log on as the Command user, you can execute actions, such as view trends, reports, or alarms/events list.
