DNC Plant/DNC Cell (FBDN1)
4 NC data management
Uploading NC data
When NC data is uploaded, the release identifier is assigned on the basis of the
configured version/identifier strategy in the DNCGLOBALSETTINGS database
table.
You can choose one of six strategies (see also: Section 10.7.2), default is
strategy 1.
Inserting NC data
When you insert NC data, the release identifier is reset and the change date is
updated. If necessary, the version is also incremented to the next free version
(see below). All other NC data properties remain unchanged.
NC data from Cut/Paste or Copy/Paste only retains its respective versions in the
node environment when it is inserted into a different group, which does not contain
any NC data file with the same name type, and version. When you copy and paste
data to the same group, the version is incremented to the next free version
number.

Note
If the parameterized maximum number of versions has been exceeded, the
"Delete Version Dialog" appears so that you can delete an old version.
