PLC archive data
The following settings are available for the "PLC archive data" and are activated when the
package is executed:
Origin of data Note
This selection can be blocked by the project engineer in order to prevent changes by the operator
during the package execution.

Preselection of the offline archive

If in the package configuration, "Package" > "Data areas" > "Use NCU/PPU"
has been activated in the tab, the archive data can be loaded directly from the
control with the "initial state" setting.
Note
No data is reset when upgrading the CNC software. The archive that is available
in the system after data migration is used.
If this option is used, the PLC memory is overall reset and then the archive data
is backed up.
If this option is used, the output data for the PLC area is taken from a stored
SINUMERIK archive.
If this option is used, no output data for this area is made available by the dialog
page.
More information is provided in the notes in the Archive data transfer (package
execution) (Page 218) section.
The selection at "Origin of data" can be blocked by the project engineer via this
option in order to prevent changes by the operator during the package execution.
At "Preselection of the offline archive", a SINUMERIK archive with PLC data
(blocks) can be preselected, pasted, or inserted as link from the list.
Alternatively, enter the path of a file which is located next to the package "/
<Path>/<File>",
e.g. "./sdb.arc".
Note
When data for "Offline archive" is entered in the step tree via components, an
archive from the overall reset state must be saved here or the "Origin of the
data" must be set to "Overall reset".
