Data buffering/backup in
the event of voltage
failures
In the event of a supply voltage failure, the AXC F 3152 saves control data, e.g., retain data
and log files, on the inserted parameterization memory (SD card).
The device firmware recognizes the voltage failure. The retain data (variables of the control-
ler that are marked as “Retain” in the PLCnext Engineer project) and log files are automati-
cally backed up on the parameterization memory.
Change: Operation with-
out SD card  Operation
with SD card
When changing from operation without SD card to operation with SD card, note the follow-
ing:
If there already is an overlay file system on the internal parameterization memory, it will be
copied to the SD card.
If there already is an overlay file system on the SD card, the controller will access it. The
overlay file system on the internal parameterization memory will be deleted.
Furthermore, all application-specific data will be deleted from the internal parameterization
memory. PLCnext Engineer projects and IP configurations stored on the parameterization
memory are no longer available. The controller accesses the data stored on the SD card.
Please note:
You can activate or deactivate support of the SD card via the WBM of the controller, see
Section 9.
Recommended:
• Deactivate the support of the SD card if you run the controller without SD card.
You thereby avoid the risk of data theft and manipulation.
NOTE: Startup of the AXC F 3152 not ensured
For proper startup of the device, the supply voltage may be switched on at the earliest 30
seconds after the diagnostic and status indicators go out.
NOTE: Data loss due to removing the SD card
If you remove the SD card during operation, data will be lost.
• Do not remove the SD card during operation.
NOTE: Damage to the SD card after formatting
The SD card is already formatted (ext4 format) and is intended for use with
Phoenix Contact controllers of the PLCnext Control product family. If you format the SD
card, certain information on the SD card that is required for use with Phoenix Contact de-
vices will be lost. After formatting, you can no longer use the SD card to operate the con-
troller.
• Ensure that the SD card is not formatted.
• If you want to delete the overlay file system from the SD card:
Reset the controller to default setting type 1.
