Trends are records of a physical or virtual object's behavior that allow you to monitor changes to the object's present value property over time. The purpose of a trend is to provide historical data about an object's performance. The Trend Viewer displays sequential data in a linear graph and allows you to export trend data. Users with the appropriate access can also add, edit, and remove data points from trended objects from the graph.
NOTICE
Trend log data is lost if a clear application and full load is performed on the device from the ABT Site tool. A partial load will not cause trend log data to be lost.
