Explanation
Files to Transfer via FTP
Display data, event data, report data, alarm summary data, manual sample data and
snapshot data files are automatically transferred at appropriate times to the FTP destination.
Data other than Excel report files and PDF report files are automatically transferred
regardless of whether the external storage medium is available.
File Type Description
Display data file Data files are automatically transferred at each file save interval.
Event data file Files are automatically transferred when the data length of data is recorded.
Report data file When the file division mode is Separate or Combine, data files are
automatically transferred when a report file is closed (or divided). For
example, data files are transferred once per month for daily+monthly reports
when the file division mode is Combine. Report data files based on report
templates (Excel report file, PDF report file) are also automatically transferred
when they are created. 1
For details on Separate and Combine, see page 1-98 in section 1.11.1,
“Setting the Report Type, Creation Time, Data Type, Etc.”.
Snapshot data file Files are automatically transferred when a snapshot is taken. 2
Alarm summary data file Files are automatically transferred when alarms are saved.
Manual sample data file Files are automatically transferred when the next time manual sample is
executed 2 and the file is divided.
1 Files will not be transferred automatically if the remaining space on the SD memory card is low
or if the SD memory card is not connected.
2 Refers to an action triggered through touch screen operation, communication command
(OExecRec), or event action function.
Shifting the Transfer Time
There may be cases when data cannot be transferred from the GX/GP to the FTP server 1
due to too many simultaneous connections to the FTP server. An example is when multiple
files are created and need to be transferred at the same time from multiple GX/GPs. By
shifting the transfer time, you can avoid having too many simultaneous connections to the
FTP server. You can shift the transfer time for display data files, event data files, and report
files.
• Even if a new event that requires an FTP transfer occurs while the GX/GP is waiting to
transfer the data of the previous event, it does not affect the transfer wait time of the
previous event. When the transfer shift time passes, all data files of the same type that
have been created (all of the files that have not been transferred) are transferred via FTP.
The following figure is an example for display data.
• To avoid accumulating too many files that have not been transferred, we recommend that
you set the transfer wait time shorter than the interval at which events that require FTP
transfers occur.
