5.1 Power Failure/Data Protection/Warm Start/Cold Start
5.1.1 General Information
The calibration data and parameters of the internal weighing electronics system are saved to the EAROM on the
weighing electronics board. Additional write protection is also available for calibration data and parameters as
well as application programs (see Chapter 5.1.5.1).
The event logger is saved to the SPI flash memory.
The flash PROM include
-
BIOS
-
firmware
-
application program
-
alibi memory
-
XML configuration files (for user management, setup, calibration, and application data)
Backups are saved to the SD card (secure digital card) (see Chapter 4.3.4).
5.1.2 Power Failure
The entire content of the SD-RAM is stored to a Nand flash memory and remains there permanently when the
power is interrupted or the device is disconnected from the power. When power is restored, all data are reloaded
from the Nand flash memory to the SD-RAM and the device is restored to the operating status before the
interruption. Dosing programs are stopped/started depending on user settings.
The SD card and the USB stick are both buffered by a battery.
If a HUB (splitter) is inserted into the USB slot and turned off, the USB stick is not buffered by a battery.
5.1.3 Warm Start
After a warm start all data remain unchanged, behaviour as after power failure, see Chapter 5.1.2.
