Trends

Displaying BACnet Trends can be done by the TrendWorX64 Viewer within GraphWorX64. The control has the capability to view real time or historical OPC data, as well as to visualize BACnet Trends.  

 

An important thing to know here is that all data are initially requested from the Trend Log object buffer (after switching GraphWorX64 to the Runtime mode). When the Notification Threshold hits, then new buffer data are requested. TrendWorX64 Viewer provides an interface for moving this data across to the user so he or she can seek and zoom to a specific portion of any loaded data (described in 'Displaying a specific portion of the data').
