I'm wondering the maximum recovery time which PI OPC HDA Interface can support


I read manual and have found this comment


"History Recovery Maximum Time

Specifies the maximum amount of time to go back in history at startup. To use, select the check box, enter a value, and choose a unit of measure. (/HI=#c, where # is a number and c is a unit, like “D” for days, “H” for hours, “M” for minutes, or “S” for seconds.)"


There is no maximum limit of recovery time, however.


How long time does PI OPC HDA Interface support for recovery at interface start-up or at recovery-only-mode?
