Visualizing BACnet Trends

If you have configured logging trends for a BACnet channel or for individual devices, you can visualize the collected trend data using the Trend Viewer in GraphWorX™ or the Data Explorer in GraphWorX or as a stand-alone tool. The following procedure describes displaying the trends in the Data Explorer in GraphWorX.

To view the trends in Data Explorer in GraphWorX:

1. Open GraphWorX in the configuration mode.
2. On the Controls ribbon, select Data Explorer, and then drag the mouse diagonally across the canvas to make a rectangle for inserting the Data Explorer control.

3. Double-click anywhere inside the control to activate its options. The activated mode is indicated by a violet rectangle around the display.

   

4. In the left pane, go to Data Connectivity > BACnet, and then expand the desired channel and device.

5. Expand the desired TrendLog or TrendLogMultipleobject, and double-click the .history data point (tag) to subscribe to it.

   

   Multiple trend data points are displayed as .history0 to .history<X> where <X> is the number of configured trends in the TrendLogMultiple object.

   

6. Select one of the options below the graph to determine the period for which you want to display the trends (from 30 minutes up to 1 week).

7. Change the default Interpolative filter (aggregate) to Raw Data to make sure you see the real values. Do the following:

   1. Double-click anywhere in the graph section to open the configuration.
   2. In the left pane of the Configure Your Control dialog, select Pen.

   3. In the right pane on the General tab, click next to the Connection field, and select Configure.

      

   4. In the Connection Configuration dialog, select Use HDA Connection.
   5. In the Filter drop-down menu, select (raw data), and then click OK. Then close the configuration dialog.
8. Use and at the bottom of the left pane to switch between a grid view with details about the data point and a graphic trend view.
