Historization Mode

How historical and up-to-date data are brought into the system is defined by the Historization Mode.
Options are:

  • Always - All values are transferred by inserting them as the current value.

  • Recent Values [default] - Only the very last value is inserted as the current value of the item, everything else is transferred as historical data without affecting the current value of the item.

  • Continuous Values - Historical data transfer works as in Recent Values mode, the transfer of up-to-date data works as in Always mode
