Adding a Trending Display

You can use the Trend Viewer to create, configure, and plot real-time or historical data trends from various sources, such as alarms and historical data, through OPC UA and other data point connections through the FrameWorX™ server.

For the Start-Up Guide, you will create a graph that displays the Tank Temperature.

Verify the Historical Data Logger service is running. ClosedLearn how

  3. Double-click the chart to display the Configure your Control dialog.

  4. Select Pen to open the General tab. Do the following:
    1. Click the Data Source ellipsis to open the Data Browser.
    2. From the Data Points tab, expand Assets > Tank Farm Management System > Tanks > Tank 01.
