NOTE:
Trend log data is preserved upon reload of a device.

Trend view allows logged data from up to 10 trend log objects to be displayed on a single chart. Data trending begins after a time sync from the network. With no time sync, data trending can begin up to the time sync window property of the device object in seconds (default is 300 seconds, or 5 minutes). Trending may begin earlier if it gets the time from the real time clock. In that case, the trend log objects would log a subsequent time change record if a time sync occurred thereafter. For more information about using the Trend Viewer, see the PXC.A Web Interface User Guide(A6V12893115).
