9.5.2 Restore data
This funcon allows you to restore the PLC runme system (rmware) and project data using a
previously created data backup. Data recovery can be carried out either by switching the
controller to power or via a device parameter.
You can also restore an older data backup. To do this, copy the corresponding
data backup on the USB sck from the "rmware\archive__" to "rmware
\acve" directory. However, the directory "rmware\acve" may only contain
one le at a me.
Do not switch o the device or remove the USB sck during data recovery!
