Setting on the "File transfer" window
■FTP server connection request timeout time
Set the waiting time from when the connection request from the CPU module to the FTP server is sent to when the response
is received. If no response is received from the FTP server within the connection request timeout time, an error occurs.
■File transfer retry time
Set the time to retry the file transfer when the file transfer fails due to an error caused by communication failure such as the
network error between the CPU module and the FTP server.
The data logging file failed to be transferred is in the standby state and the retry starts. The file is resent until the file transfer
retry time elapses. Even when the file transfer fails again due to a communication error, the file will be on standby for the
reverse transfer again without an error of the data logging file transfer function.
Ex.
When a data logging file of the data logging setting No.1 has not been transferred due to a network failure
The retry ends when the network is recovered and retry of the file transfer succeeds.
■Matching the folder structure of the transfer destination FTP server with the CPU module
When the data logging file is transferred, the directory is automatically created in the specified folder path of the FTP server so
that the structure is the same as the storage destination ( Page 949 Folder configuration).
If the same file exists, the file will be overwritten.
• When the folder structure is matched with the CPU module
The folder path (1) specified in the server setting, folder structure (2), logging files transferred (3).
In the folder structure (2), subdirectories (4) are created.
