Reduce Flash Wear By Storing Data On Sd Cards - Beijer Electronics BoX2 base v2 Configuration Manual

When a change in parameters, tasks or other parameter related options are changed, no online
change can be performed. BCS Tools will prompt with a message asking if you want to perform a
download instead. Click Yes or No. Clicking Details... shows the code generation timestamp of the PC
vs the PLC.
Boot Application
The Boot Application is the program code that the CPU will load and execute, after powering on or
resetting the system.
When a download is made with the CPU in STOP mode, the downloaded project will be registered as
a Boot Application.
An online change updates the Boot Application per default.

5.5. Reduce Flash Wear by Storing Data on SD Cards

Beijer Electronics recommend using industrial SD card instead of the built-in flash memory when data
logging is performed. The capability to use external SD card for data logging on BoX2 devices was
introduced in iX Developer 2.40 SP5. Since extensive writing to the flash memory can cause wear
problems and possibly premature failures, the alternative to write to an exchangeable SD card will
potentially lengthen the lifetime of the device. An SD card is easy to replace compared to a built-in
memory. In addition, the memory size of the SD card is normally much larger than the built-in flash
memory.
To set up the SD card database in iX Developer:
Go to Project/Settings. Select Database and select SD Card in the dialog.
1.
Click on the OK Button to confirm the new settings.
2.
When the location of the database is changed from flash to SD card (or vice versa) in an existing
application, the database will be automatically copied to the new location once the project is
transferred to the device. This will be started immediately after the project transfer has taken place
and hence a somewhat slower project start-up time can be noticed.
It is advisable to do a backup of the database in case something happens during the database copy
operation.
If during runtime of the device, the SD card is removed and the chosen location for the database is
the SD card, the panel will close the application and attempt to reboot until either an SD card is
