The analyzed time range and duration are displayed in the title bar.

The table contains one line per signal.

Signal	Name of the trace variable Example: `PLC_PRG.S1`
Index	0-based index of the signal order
N	Number of measurements for the calculations
Min	Minimum value
Avg	Average
Median	Value which is located in the middle position when the values are ordered by their size
RMS	Root mean square
StdDev	Standard deviation
Max	Maximum value
Integral	Integral
Min Δt [s]	Minimum value of the time intervals of successive values
Avg Δt [s]	Average of the time intervals of successive values
Median Δt [s]	Median of the time intervals of successive values
StdDev Δt [s]	Standard deviation of the time intervals of successive values
Max Δt [s]	Maximum value of the time intervals of successive values

Click a column heading in the table

CODESYS sorts the table by that column, toggling the order between ascending to descending.

Default: The table is sorted by the Index column in ascending order. The signals are then sorted in the same order as in the signal tree.

Click in the line

The line is selected. You can select or deselect other lines by pressing Shift+Arrow.

Ctrl+C

CODESYS copies the selected lines as text to the clipboard. The values of the individual columns are tab-separated, and the lines are delimited with the control character CR or LF.

Requirement: You have selected one or more lines.
