You use trend logs to record values from devices, such as sensors. A trend log can also log consumptions, such as energy consumption or water consumption.
You can view a trend log as a trend log list or as a trend chart.

You can copy trend data between EcoStruxure BMS databases by exporting trend log data from a trend log list to an .XML file and then importing the trend log data from the .XML file to a trend log.
The .XML file contains a time stamp, value, and comment for each record. The file also contains the locale setting that you can edit in the .XML file.
