You export a trend log list to XML format if you want to open it in an XML editor for viewing and processing.
When you are exporting log data and then importing it to another EcoStruxure BMS, change the time zone to UTC before the export to make sure the imported time stamps show the correct time
In WorkStation, in the System Tree pane, select the trend log list you want to export.
On the Trend Log List toolbar, click the Export to .XML button
Browse to the folder where you want to save the file.
In the File name box, type a name.
Click Save .
The trend log list is now exported to XML format.
