9.6 Saving Recorded Data on an SD Card
In addition to the internal ring buffer, the Sunny WebBox can also save data on an SD card.
1. Select "WebBox > Settings > Security" in the user interface.
2. Make a selection in the "External memory" field.
3. Insert the SD card into the Sunny WebBox SD card slot.
☑ The SD card is configured. The Sunny WebBox will now save data to the SD card.
When an SD card is inserted into the SD card slot, the Sunny WebBox copies all data from the internal
memory to the external memory (SD card). The Sunny WebBox will save new data to the SD card
until you remove it from the SD card slot. The "MEMORY" LED on the Sunny WebBox flashes orange
to indicate that it is writing to the SD card.
The Sunny WebBox creates a file folder on the SD card. The name of the file folder is
"WebBox_[SerialNumber]". "[SerialNumber]" designates the serial number of the respective
Sunny WebBox. The Sunny WebBox creates a subfolder in the main folder every day.
Each subfolder contains all the data collected by the Sunny WebBox on that particular day.
The Sunny WebBox will not save further data onto the SD card once the SD card reaches its storage
capacity ("MEMORY" LED lights up red). Replace the SD card or format the SD card in your
computer.
Compatibility of the SD cards
To ensure that the SD card works correctly, use SD cards available from SMA.
Compatibility with all SD cards available on the market cannot be guaranteed. The
Sunny WebBox does not support SD cards with storage capacities of more than 2 GB
or SDHC cards.
Formatting the SD card
Only use SD cards which have been formatted with the FAT16 file system.
The Sunny WebBox formats the SD cards with the file system TFAT to increase data
security. If you wish to clear the SD card, you must format the SD card on a computer with
the FAT16 file system.
"Enabled" Plant data is saved on the SD card.
"Disabled" No plant data is saved on the SD card.
Data loss when removing the SD card
Do not remove the SD card while the "MEMORY" LED is flashing orange. This can damage
the file system of the SD card and lead to data loss. Depending on the amount of data, the
writing process can take some time.
