Chapter 12 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.
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 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.
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
software and NOT via Controller Lock feature.
IMPORTANT
If the Load Always setting is enabled and power is lost when restoring a
project from the microSD 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, or the wrong project will be loaded.
The default project name is the name of the controller, for example
“Micro850”, and the default directory is “Micro850\USERPRJ”.
If you change the name of the controller from the default, you must
configure the UPD setting in the ConfigMeFirst.txt file.
