(6) Starting data logging during file transfer
Another data logging cannot be started to the same file being transferred. If the start operation is performed, the
following window appears. Select whether to start the data logging or not.
Clicking "Yes" will stop transferring data logging files. (Files not yet completely transferred may remain on the
FTP server. Standby data logging files (including files during retry processing) will no longer be on standby, and
an error will occur.)
(7) Data logging file that results in a file transfer error
If an error caused by communication error, file access error, or file transfer stop error occurs during file transfer,
data logging files not yet completely transferred may remain on the FTP server. Since unreliable, the logging files
should not be referred to (Data logging files in file transfer error can be checked in the "File Transfer Error Log"
window).
(8) Latch clear during data logging file transfer
If latch clear is executed during data logging file transfer, data logging status will be unregistered. The operation
will be in the same status when the data logging stop operation is performed.
(9) Powering off and on or resetting the CPU module during data logging file
transfer
If the CPU module is powered off and on or is reset during data logging file transfer, data logging files not yet
completely transferred may remain on the FTP server. Note that transfer of a standby data logging file (including
a file that were in retry process) and a data logging file that was being transferred will not be resumed.
