Data
The Data window displays the history of value changes for the selected
object as a table with the following columns:
| Column | Description |
|---|---|
| Source Timestamp | The value’s time at its source, with millisecond precision |
| Value | Object value |
| Quality | Value quality flag |
| Server Timestamp | Time when the Server received the value |
Each row is one change of the value recorded in the archive. The window is built from the Server’s archive: an object without a value archive shows no rows for past periods (see Reports and analysis).
Clicking the first column header toggles the sort order by time between ascending and descending.
Period
The period is set with the Period commands on the command bar — see Choosing a period. A new window starts with Day. The period is saved with the window.
If you select two or more rows and choose Graph or Summary, that window opens over the span from the first to the last selected row.
Printing and export
The window can be printed and exported to CSV with the Print and Export to CSV commands. The printout and the file contain the rows in the current sort order, but not the object name or the period — add them yourself.
