Manual
Draft version 1.2.1 from 2017-09-13, valid from FW Version 02.06.20(09)
The controller has an automatic update function. If this function is activated on a
memory card before the data backup and a controller is booted from this memory
card, this data is restored automatically on the internal memory of the controller.
Only one package may be copied to the network!
If you have specified “Network” as the storage location, only one package may
be selected for each storing process.
No backup of the memory card!
Backup from the memory card to the internal flash memory is not possible.
Account for backup time
Generation of backup files can take several minutes. Stop the CODESYS
program before you start the backup procedure to help shorten the time required.
4.2.2.2 Restore Function
The restore function is used to load the data and device settings from the
memory card to the internal memory during operation.
The restore function can be called via the WBM page “Firmware Restore” or the
CBM menu “Firmware Restore.”
The network or, if it is inserted, the memory card can be selected as the source
medium.
If the memory card is selected as the source medium, the LED above the
memory card slot flashes yellow/orange during the load operation.
When loading the data, the files are copied from the directory media/sd/copy/ of
the source medium to the appropriate directories on the internal memory.
The device has an active and an inactive root partition. The system backup is
stored on the inactive partition. Startup is then performed from the newly written
partition. If the startup process can be completed, the new partition is switched to
active. Otherwise, booting is performed again from the old active partition during
the next boot process.
The boot project is loaded automatically and the settings automatically activated
after a restart. The “Boot project location” setting on the “General PLC Runtime
Configuration Web” page of the WBM determines whether the boot project of the
internal drive or the memory card is loaded.
