Buffer memory

When the number of the warning history exceeds 15, the newer warning information is stored from pointer 0 again and the

previous warning information is overwritten.

Warning history pointer

Stores a pointer number that comes next to the number assigned to

the latest warning history record.

• 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.
