SFTP/FTP push

Last modified:


The SFTP/FTP push blue'Log XM/XC license activates the push function on your blue'Log, allowing you to send measured data to VCOM, or an FTP/SFTP server of your choice.


❗

Warning

For cybersecurity reasons, we strongly recommend using SFTP instead of FTP.

Set up SFTP/FTP push

Prerequisites

  • The FTP/SFTP server must be currently available to save your settings.

Steps

  1. Navigate to Plant > SFTP/FTP Push.

  2. Activate the toggle Push service.

  4. Under Protocol, select FTP or SFTP, and enter the server name.

  5. Select the relevant Port. Use the arrow selector to change the port number.

  6. To push your data to a specific directory, enter the name of the Upload directory.

  7. Enter the username and password for your server.

  8. You have the option to push historical data.

    • VCOM ONLY Navigate to Plant > VCOM.

    • Activate Historical data.

    • Select the period for which to transmit historical data.

SFTP/FTP push is now set up. Check the server for transmissions.

About XML files and the Gzip files

  • An XML file contains 5 x 1 min.

  • All time stamps in the file use the UTC format (example: 2018-01-14T10:00:00Z).

  • For transmission intervals of > 5 minutes, several files will be sent each time (for 60 minutes: 12 XML/gz files).

  • Each XML file is compressed and transferred as a Gzip file.

File name

XML

<Serial number>_<date>_<start time of the data>_<end time of the data>

The XML file is based on our VCOM import specification.

Example of units

As a rule, SI units are used by the data logger. Units that differ from import specifications are found in the area <abbreviations>.
