Chapter 10 Using microSD Cards
Restore Project from Backup
The last step is to restore the project to your controller from the microSD card.
There are two methods to restore the backup, depending on the configuration
of the controller.
Existing Controller - Load Always / Load on Error
For this example, the Load on power up setting was configured to “Load
Always”. This means that the controller loads the project from the memory
card whenever it is powered on.
1. Insert the microSD card into the microSD card slot.
2. Cycle power to the controller.
3. When the SD LED displays a steady green light, the project restore is
complete.
This method is used for an existing controller that has been configured and
you want to update the program.
New Controller
If your controller is new, you can use the ConfigMeFirst.txt file to restore the
project backup.
Figure 15 - Example Configuration for Project Restore
In the example shown above, the ConfigMeFirst.txt file configures the IP
address, subnet mask, and gateway of the controller, and restores the project
from the location specified on the microSD card.
The ConfigMeFirst.txt file must be placed in the same root directory as the
backup folder in the microSD card.
1. Insert the microSD card into the microSD card slot.
2. Cycle power to the controller.
3. When the SD LED displays a steady green light, the project restore is
complete.
Data Log
The data logging feature allows you to capture global and local variables with
timestamp from the Micro800 controller into the microSD card. You can
retrieve the recorded datasets on the microSD card by reading the contents of
the microSD card through a card reader or by doing an upload through the
Connected Components Workbench software.
