● Unprocessed buffer size
The size of the unprocessed buffer (internal memory), which temporarily accumulates sampled data from the CPU module, is
stored. (If the size is 20, the buffer can accumulate 20 times worth of data sampling processing.)
The accumulated data is processed by the report creation processing. For details on the unprocessed buffer, refer to the
following:
Page 350 Checking sampling process time
● Unprocessed data count
The amount of data accumulated in the unprocessed data buffer is stored.
Current : The newest unprocessed data count is stored.
Maximum: The maximum value of the unprocessed data count is stored.
If the unprocessed data count reaches the unprocessed buffer size, processing overload count occurs during the next data
sampling process. When the unprocessed data count tends to increase, processing overload count may occur from the
elapsed time. Take corrective actions by referring to the following:
Page 350 Checking sampling process time
● Creation trigger detection count
The number of creation trigger occurrences detected is stored.
The creation trigger reoccurrence count is not included.
● Creation trigger reoccurrence count
After the creation trigger occurred, the number of creation triggers that was ignored due to the recurrence of the trigger during
report creation is stored. (The number of creation triggers is not stored when "At the data logging file switching" is set to the
creation trigger condition.)
Take corrective actions by referring to the following:
Page 350 Checking sampling process time
For operation when the creation trigger continuously occurs, refer to the following:
Page 74 Creation trigger function
● Report creation time
The time required to create a report is stored in seconds unit.
• Newest : The time required to create the newest report
• Maximum: The maximum value of time required to create a report up to the present
