Device Tree

The device tree appears on the left side of the main window. It displays all interactive items in the system. Each type of item is represented by one of the following icons:

Alarms - Monitors specified conditions and generates an alarm message and optional email alerts.

Calculations - Reads the value of one or more points and performs a calculation on them. For example, averaging several temperatures.

Devices - Any physical device, panel or I/O unit in the system.

Drivers - A physical network or logical grouping of devices based on the protocol they use. For example, an entire LonWorks network is a single driver.

Folders - Used to help organize other items. Folders may contain other folders.

Graphics - Used to display information from the system and to control equipment.

Points - Any physical or logical control point on a device. Inputs, outputs, setpoints and variables on a device are all considered "points".

Runtimes - Monitors specified conditions and accumulates the amount of time the conditions are true, and generates a message and optional email alerts when a limit is reached.

Schedules - Allows for control of several points based on the time of day.

Site - The root item from which all other items branch.

Trends - Automatically records point values at specified intervals to allow for later viewing.

Navigating the Device Tree

Drivers, devices and folders may contain other items. Click the item to open it and display any sub-items. Click again to close the item and hide the sub-items.

Clicking any other item will display a viewing/editing screen for the item. Click a graphic to view it, click a point to display and control the value, etc.

Right-click any item and select "Collapse" or "Collapse All" to close an open folder or all open folders, respectively.

Editing the Device Tree

Right-click any item and select "Delete Item(s)" to remove them from the tree.

Deleting an item will also delete all sub-items beneath it in the tree.

Clicking and dragging an item allows it to be moved. Note that there are several restrictions on where items may be dropped. Generally, items under a device may only be dropped on a folder under that same device, or on the device item itself. Devices under a driver may only be dropped on folders under the same driver, or on the driver itself.

If an item needs to be moved outside of these restrictions, right-click the item, save it as a template, delete it and then recreate it from the template at the new location. Note that the points attached to items using this method may need to be re-attached

Multiple items may be moved or deleted at the same time. Hold down the Ctrl key and click an item to select multiple items. Hold down the Shift key and click an item to select all items from the highlighted item to the newly clicked item. Note that the restrictions explained above still apply when moving multiple items.

Adding Items

Right-clicking an existing item in the tree will display a pop-up menu with options to create new items. The items available will depend on the type of item clicked.

Editing Items

Right-click any item and select "Properties" to edit that item. An editor screen specific to that item will be displayed.

Save as Template

Right-click any item and select "Save as Template" to save the item, and all sub-items beneath it as a single template. This template may then be restored later to clone the items. See Templates for more information.
