Application data backup
I need to save the applications with current cold retain values.
Is it possible to save the backup of applications along with current status from AC800M Controller?

There is no way to take the application backup from controller (AC800M) to a flash card.
If your requirement is to save the data as backup, you can do that in two parts.
1) Application Backup
As soon as you download the application to controller, you can use the option "Download to Removable Media" from control builder to create the application backup in CF Card.
2) ColdRetain Values
The cold retain values can either be saved periodically via the settings in the control builder or from the code in application using "SaveColdRetain" function block.
