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.

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.

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

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

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.
