|
“Avg Δt [s]” |
Average change of time intervals for successive values |
|
“Median Δt [s]” |

Click a column head in the table. |
CODESYS sorts the table by that column, changing the order from ascending to descending and back. Default: The table is sorted ascending by the “Index” column. The signals are then sorted in the same order as in the signal tree. |
