Chapter 9 Using microSD Cards
Project Backup and
Restore
Project backup and restore on Micro820 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, the
2080-REMLCD module, 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 powerup, restore automatically occurs if the Load Always or Load
on Memory Error option has been configured in Connected Components
Workbench.
The microSD card stores the controller password in encrypted format. When the
password is mismatched, the contents of the microSD card is not restored on the
controller.
IMPORTANT
To learn about restore and backup using the 2080-REMLCD module, see
Using the Micro800 Remote LCD on page 85 .
To learn about restore and backup using the Connected Components
Workbench, refer to the software Online Help.
IMPORTANT
For Micro800 controllers that support microSD cards, IP protection of
user project can only be achieved through the POU password protection
mechanism in Connected Components Workbench (Developer Edition)
and NOT via Controller Lock feature.
IMPORTANT
If the Load Always setting is enabled and power is lost when restoring a
project from the micoSD card, the controller will attempt to load the
project using the default project name and directory after power is
restored. If your project is not using the default name and directory, the
operation will fail and a fault occurs.
