Millisecond pause between history calls
The number of milliseconds to pause between history recovery calls.
(
/HRPAUSE=millisecond )
The Use Default button is used to reset the value to the default setting of 0 milliseconds to
pause between history recovery calls.
Use history recovery only (no snapshot data collection)
If this check box is selected, tags do not sign up for exceptions. Each scheduled scan time
(each scan class), history recovery is done from the last snapshot value to the current time.
This box must be checked if you want to enter a History time range. (
/HRONLY )
History time range (dd-mmm-yy:hh:mm:ss,dd-mmm-yy:hh:mm:ss)
Alternately, specifies a range of history to recover before exiting. The times must be specified
using Historian Time string formats with a colon separating the date and the time. For
example:
10-dec-98:10:00:00,10-dec-98:12:00:00
Note that these times are local to where the interface runs.
This will recover two hours of data from the source to receiving system; put it into the
receiving FactoryTalk Historian System snapshot for all points and then exit. This switch will
override the normal checking for the most recent snapshot time in the receiving database, thus
out of order data may result. When time-range history recovery is enabled, the value specified
by the
/RH parameter is overridden. ( /HRONLY=dd-mmm-yy:hh:mm:ss,dd-mmm-
yy:hh:mm:ss )
Start history recovery beginning with the first value prior to the start time.
This will retrieve history for all the points starting from the value immediately prior to the
start time. The default is to begin with the first value after the start time. This can only be
checked if the Use history recovery only check box has been checked.
