4.3.1 Version management

General
DNC allows you to parameterize the maximum number of NC data versions to be
stored.
Machine-specific version management uses version zones to define the hierarchy
level within which NC data with the same name, type, and version can occur.
A version zone can contain up to n items of NC data of the same name and type
provided that the version numbers are different.
The default setting is n = 5, but this can be changed depending on the project.
Note
A version zone can only contain one released version.
Machine-specific version management
Machine-specific version management defines where identical NC data can
appear:

Group: Identical NC data must be unique within the group.

Machine: Identical NC data can appear on different machines. The names on
one machine must be unique, however.
Note
Only the selected version zone is taken into account for the release and when
versions are determined.
