Data collection, file store time, and storing method
If a monitor screen is displayed, the AD57G collects and stores the data
to the file for each data collection trigger.
The completion of data collection and file storage for each logging report
depends on how the collection freq. and overflow action are set in the
AD57GP Set report parameter window.
The following shows how to collect and store data:
Overwrite
stop
Stores data serially from the head record (record 1).
When the data is stored to the last record corresponding
to the collection freq., the data from the head record is
stored (overwritten).
This is repeated at specified intervals.
Stores data from the head record (record 1) sequentially.
When data is stored to the last record corresponding to
the collection freq., data collection and file storage are
interrupted.
(Hereafter, the data collection trigger is ignored.)
During monitoring, to resume the data collection and file
store for this report, deleting the data correspond~ng to
the report data file is necessary.
