Default Trend Pages

A project created using the Situational Awareness Starter Project will include a default trend page that is accessible from the runtime Header Bar. Click on the icon below to display a trend page in the page content area (see Default Layout).

The default trend page allows you to analyze specific trends and alarms for equipment. The layout of the default trend page features the following sections:

Behaviors that you will observe when you navigate between pages include:

• Navigating to a different page within the Workspace will not affect the trend page. Your pens, currently selected object in the Object Tree and any text entered in the Search box will be retained.

• Navigating to a different page and selecting a different equipment and then navigating back to the trend page will clear the entry in the Search box and also select the equipment in the equipment tree.

• Navigating to a different page and selecting a different equipment and clearing that selection before navigating to the trend page will retain your configuration on the trend page.

  Note: You can launch the trend page from other pages using the buttons in the Information Zone's Trend tab. This will launch the trend page with the trend for the object selected on that page.

Tree View

The tree view provides a hierarchical view of a project’s equipment hierarchy.

The tree view displays:

• Check marks for objects that have an active trend.

• Gray check marks for objects whose children have an active trend.

• Alarm counts that indicate the number of associated alarms in the top three alarm priorities, as well as the number of shelved alarms.

• Buttons to expand (+) and collapse (-) the tree.

• Search box that you can use to filter the displayed list of objects.

Trendable Items

The Trendable Items section lists the items associated with each piece of equipment that you can add to the trend chart.

The following icons indicate the 'type' of an item (tag):

A check box is displayed for each applicable type. Select the required check boxes to add them to the chart. Up to 16 trends can be added. When the limit is reached, the check boxes are hidden.

Trend Chart

Displays the trend chart based on the selected equipment and options.

Main Toolbar

The Main toolbar is located above the chart. It contains commands that allow you to perform general operations, such as save and open views, print reports, and so on. The table below describes the buttons that are included on the main toolbar.

Navigation Toolbar

The Navigation toolbar contains commands to allow you to navigate forward or backward through trends, as well as other navigation-related tasks.

A Start Time Picker is located on the left-hand side of the navigation toolbar, an End Time Picker is located on the right. You can use these to Specify a Start Time and End Time. If a time picker control is using Daylight Savings time, the clock to the left of the control will have a shaded segment.

The Span Picker contains commonly used predefined time spans that you can select from a drop-down menu. The time span of the trend display represents the difference between the start time and the end time. Selecting a time span adjusts the start time and leaves the end time as it is. To set a time span that is not included in the list of predefined times, see Set a Nonstandard Time Span. See Also Lock/Unlock the Time Span.

The Navigation toolbar also includes a set of command buttons. You can use these buttons to perform the following tasks:

• Navigate Time

• Synchronize to Now

• Toggle Autoscrolling

• Zoom In/Zoom Out

• Undo Last Zoom

• Toggle Box Zoom

• Edit Vertical Scale.

Object View

The Object View displays the list of objects (equipment) displayed in the trend chart along with properties of the pens such as name, color, scale and so on. The following properties are displayed:
