Backing up log files, Data access via FTP

Operation and Data Access

Backing up log files

The old data is located in the compact flash card. If you have a standard card reader for the PC, you can copy the *.txt files to your PC. The path is WEB \ ARCH. You can copy the Files with the name *.txt to your PC and then you can delete them from the compact flash card. After this you have memory space free.

Do not plug in and out the flash card while Webserver is running - switch off before.

With the browser you can only look to the old data for example http://172.24.51.92/arch/0406A03.txt This will show you the archive data of year 2004 and month 6 (June) of bus member with address 3 You can only download this file to your PC with the Browser. It is not possible to delete with the browser.

With an FTP program (for example PSFTP1.3) it is also possible to download or to delete the stored txt-files with telephone line. First you have to call the Webserver, and then you have to install an FTP connection with login name and password (with PSFTP1.3). Change to drive b:\web\arch.

Then you can download or delete the txt files

Data access via FTP

The CF card must also include the firmware of the ChemWeb Server. Therefore it is not allowed to modify or delete any other files from the CF card than the log files described above! This would cause data loss and failure of the ChemWeb Server!

The stored log files can be transmitted from the CompactFlash card to own drives with any FTP program via any network connection. For this purpose, a connection must be established to the ChemWeb Server using the FTP program. The defined login name and the password must be entered. Only one simultaneous connection is possible!
