Issue
Does Continuum support multiple object trend reports?
How can I display a report that shows the trend data for multiple objects.
Environment
- Continuum
- CyberStation
- BACnet
- TrendLogs
Cause
While trend data for a single BACnet point can be reported from the TrendLog object by selecting View Report from the Data page of the TrendLog object editor, it is usually necessary to display comparative trend data from multiple points.
Resolution
- Since BACnet points themselves do not store trend data the way Infinity points do, BACnet requires that another object, the TrendLog object, be used to store this data in the controller.
- The trend data for a single object can be viewed by selecting View Report from the Data page of the TrendLog object editor to which the point is attached.
-
Continuum Report objects can be used to view BACnet trend data.
- Unlike Infinity points, BACnet points are not added to the Report objects member list since BACnet points contains no trend data.
- Instead the TrendLog object which has been configured for, and to which the BACnet point has been attached, is added to the Continuum Report TrendLog member list.
- Multiple TrendLog objects can be added to the member list of a Continuum Report.
- The member list is the Trend Log window found on the Filter page of the Report object editor.
-
The configuration of the Report object editor should be as follows.
- Data Source: Current Value
- Report Type: SnapShot of Trend Log buffer contents.
- Chart Type: Text (data schedule) or Trend (graph)
