Chapter 10 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.
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.
Backup and restore can be configured to trigger through the following ways:
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.
