• Pointer numbers are assigned to each chunk of buffer memory that
configures one warning history.
Ex.) Pointer number 0 = Buffer memory 1358 - 1361, 1472
Pointer number 1 = Buffer memory 1362 - 1365, 1473
Pointer number 2 = Buffer memory 1366 - 1369, 1474

•
Pointer number 15 = Buffer memory 1418 - 1421, 1487
• History records are stored using pointer numbers labeled "0 -15".
The sequence repeats once the maximum number of history
records is reached, and so the 17th history is stored using pointer
number "0".
The old history record is overwritten by the new record.
