Transfer specifications and start timing of the data logging file
Data logging files are transferred at the file switching timing in the data logging function.
■Transfer specifications of the data logging file
• Data logging files are transferred one by one from each setting number (folder).
• If multiple files exist in multiple setting numbers, a file which has the smallest serial number in the lowest setting number is
transferred.
• Only one file per setting number can be the standby file.
For example, in the following data structure, files are transferred from the file . (Files are transferred in order from   
...   .)

LOG03

• If an error occurs during a file transfer, the data logging file caused the error is omitted from the standby files. A following file
in the same setting number becomes a new standby file.
• If the file switching timing occurs during a file transfer, the file that has been being transferred becomes a standby file.
• If the data logging operation is completed or the user has operated CPU Module Logging Configuration Tool to stop data
logging, the data logging file transfer is stopped at the completion of the transfer of the stored data logging files.
