Redundant data backup on memory card

In conjunction with the "Firmware update via web server" and the associated remote access,
the "Redundant data backup on memory card" provides secure access again to the device in
the event of an interruption of the connection or the power supply. This redundant data backup
cannot be deactivated.
As of firmware version V4.6, the memory cards have a backup partition in addition to the normal
working partition. The most important data is duplicated on this backup partition during ramp-up
of the CU. This ensures that when you update the data on the memory card a data loss cannot
occur due to a power failure. Only the system can access this backup partition. The partition is
not visible for users.
If damage to the file system is detected on the memory card, the system reconstructs the data
on the working partition from the backup partition at the next ramp-up of the CU. The fault
"F01072: memory card recreated from backup copy" is emitted. A running restoration of the
data is indicated via the LEDs (FW Loading). Generally, the restoration of the data takes one
minute.
The duplication of changed project data on the backup partition takes just a few seconds during
ramp-up. After write operations on the working partition (e.g. RAM to ROM), the system
automatically recognizes when an update of the backup copy on the backup partition is
required and issues the message "A01073 (N): POWER ON required for backup copy on
memory card". In this case, perform a POWER ON for the Control Unit or a hardware reset (via
p0972).
As of firmware version V4.6, there may be a substantial data backup at the first ramp-up with
a memory card. Generally, this data backup only takes a minute and is indicated via the LEDs
(FW Loading). Such a data backup is also performed once for a firmware update or hotfix of the
memory card via the card reader (as of V4.6).
Incorrect parameterization due to software manipulation when using exchangeable storage
media
The storage of files on removable storage media involves a high risk of infection, e.g. via
viruses or malware. As a result of incorrect parameterization, machines can malfunction,
which in turn can lead to injuries or death.
● Protect the files on removable storage media against harmful software through appropriate
