Example applications

You have several Web-Thermometers (e.g. Web Thermometer Pt100/Pt1000) in your network and want to archive their measurement values centrally. To do this, configure regular sending of the current measurement values for each Thermograph via FTP. Specify your SD Data Station as the FTP server. In this way you can create central measurement data archives in the internal memory of the Box or on the SD card. This archive is then available at any time for further processing.

In "Data Filling Station" mode files saved on the Box can be moved to an inserted SD card by pressing a key. Use this function for example to retrieve measurement archives from mobile equipment at regular intervals without a network connection.
