11 DATA LOGGING FUNCTION
11.8 Data Logging File Transfer (Auto Transfer to FTP Server)
File transfer test
Check the communication status and settings by transferring a test file from the CPU module to the FTP server. The file
transfer to the FTP server can be checked before system operation.
■Procedure for the file transfer test
The following describes the procedure for the file transfer test.
1. Configure the transfer destination server setting in CPU Module Logging Configuration Tool. ( Page 979 File
transfer)
2. Click the [File Transfer Test] button in the "FTP Setting" window to execute the file transfer test.
3. Check the execution result.
4. Check that the test file is transferred to the FTP server. ( Page 198 Structure of a test file)
■Structure of a test file
The following table lists structures of a test file to be transferred to the FTP server.
■File transfer test specification
• The FTP server connection request timeout time is fixed to 10 seconds.
• Even if the file transfer test fails due to a communication error, the retry is not executed.
• Even if the file transfer test fails, the error is not stored in the file transfer error history. ( Page 992 File Transfer Error
Log)
■Precautions
• File transfer tests cannot be executed simultaneously with another configuration tool. Execute the file transfer test after the
file transfer test from another configuration tool is completed.
• If the engineering tool is operated or monitored from the same connection destination of the same computer during the file
transfer test, the operation or monitoring will be executed after the file transfer test completion.
