Trend Log Lists
The trend log list numerically displays the records of a trend log or an extended trend log. The records of the trend log can be processed by a calculation method before they are presented in the trend log list.
The trend log list can only display one trend log at a time and must be manually refreshed to display recently recorded values.
You can manually add records to a trend log list for any type of trend log.
Time Zone Modes in a Trend Log List
In a trend log list, you can present the records of a trend log in different time zones: local time zone, SmartStruxure server time zone, and UTC time zone.

Calculation Methods
Use a calculation method to process the records of the trend log before presenting them in a trend log list or a trend chart. The original records in the trend log are not affected by the calculation method. The calculation method is applied to the trend log records grouped by a specific time interval.
