Chapter 11 Using microSD Cards
Project Backup and Restore Project backup and restore on Micro830, Micro850, and Micro870 controllers
are mainly supported through the microSD card. Both backup and restore can
be initiated or manually triggered and configured through the Connected
Components Workbench software, and the ConfigMeFirst.txt file in the
microSD card. These backup files are not the same as Connected Components
Workbench project files.
Backup and restore can only occur when the controller is in PROGRAM mode.
On controller power-up, restore automatically occurs if the Load Always or
Load on Memory Error option has been configured in the Connected
Components Workbench software.
In Connected Components Workbench software version 20.01.00 or later,
when you use the Micro850 (2080-L50E) and Micro870 (2080-L70E) controllers
with the microSD card plug-in module, the encryption functionality option is
added to help enhance the encryption capability on your programs for better
security protection.
If you select the option “Enable Encryption on user backup project”, the time it
takes to restore the program can increase up to 10 times, depending on the size
and content of the program.
IMPORTANT
Do not remove the microSD card or power down while operations such as
upload, download, delete, search, backup, and restore are ongoing to
prevent data loss. A blinking SD status LED indicates that these operations
are ongoing.
Note the following:
• The SD status LED will not blink when flash upgrading the firmware from the
microSD card.
• The SD status LED does not blink continuously for the entire duration of the
restore operation.
IMPORTANT
To prevent data loss, recipe and data log function blocks must indicate Idle
status before microSD card is removed.
IMPORTANT
To learn about restore and backup using the Connected Components
Workbench software, see the software Online Help.
