Flow of data collection
Collected data is stored in the internal buffer, where the data is partitioned at END processing and saved in the SD memory
card.
The size of data to be collected per END processing is determined according to the capacity setting of the internal buffer (
Page 188 Internal buffer capacity setting) and the individual area size of devices to be collected. Data is collected and
partitioned into the groups per END processing, as in the table below. If the capacity of an individual area exceeds the internal
buffer capacity, collected data in the individual area is further partitioned. The first 1K byte in the internal buffer is used as the
system area, and thus the collection size per END processing is determined to a value of the internal buffer capacity minus 1K
byte.
Effect on the scan time
The greater the number of collected points, the longer the scan time. For the increase in scan time due to the collected points,
refer to the processing time. ( Page 910 Memory dump function)
Partition area Remarks
Device area If the total value of devices exceeds the internal buffer capacity, the amount by which the internal buffer
capacity is exceeded is collected at the next END processing in order from the top device, not collected
at the current END processing.
Local device (at each program) If the total value of local devices of programs concerned exceeds the internal buffer capacity, the
amount by which the internal buffer capacity is exceeded is collected at the next END processing in
order from the top device, not collected at the current END processing.
