12.2.4 Backing up NC active controller data

NC active data
The auto archive function can only archive controller data that can also be saved in
a file in the file system at the operator interface. The Backup NC active data
function can be used to partially rescind this restriction.
Data that is located exclusively in the NCU/NCK is stored in a data archive that is
regenerated by DNC during each archive run and saved there in ASCII format. This
data, which cannot be entered individually (e.g. drive data or GUD variables), is
called NC active data.
During the auto archive run, a data archive containing the NC, PLC, and file system
data can be created prior to the archive run using a predefined subset. This archive
is stored in the archive directory of the data management system (ARC.DIR) and
archived too via the auto archive mechanism.
One archive file, which is created in the archive directory prior to the archive run,
can be defined for each machine. If it already exists, it will be overwritten.
An input file is used to define which data is included in this archive file.
Settings for this function must be made both on the controller and on the DNC
master computer.
This function allows you to create standard archive files.
You can define which sub-areas of the NC active data are to be taken into account
and then read and stored in the archive file via the DNC Cell/Plant auto archive
function.
This function is based on the service server interface (ARServer.EXE).
Note
You cannot create a series startup archive or an upgrade archive.

Important
The Backup NC active data of the controller function is realized only for
PCU 50.
