Warning history pointer
Stores a pointer number that comes next to the number assigned to
the latest warning history record.
Buffer memory
address
• A pointer number is assigned to each group of buffer memory addresses
that stores one complete warning history record.
Example: Pointer number 0 = Buffer memory addresses 1358 to 1361, 1472
Pointer number 1 = Buffer memory addresses 1362 to 1365, 1473
Pointer number 2 = Buffer memory addresses 1366 to 1369, 1474
Pointer number 15 = Buffer memory addresses 1418 to 1421, 1487
• A pointer number 0 to 15 is assigned to each history record and the record is
stored in chronological order. A pointer number 0 is reassigned to the 16th
history record and the 16th record overwrites the oldest history record.
