4 NC data management

4.7 Consistency check

4.7.1 General

The consistency check is used to check for and rectify inconsistencies between the
NC administrative data records in the database and the NC data files in the DNC
file structure.
A quick consistency check is performed each time DNC Admin is started. If
inconsistencies are found, a message popup is displayed drawing the user's
attention to this.
Inconsistencies can occur, for example, if an old backup of the database is
imported, which means that database entries are missing or that there are too
many entries.
Inconsistencies must not occur under normal operating conditions. In this context,
"normal operating conditions" means that the database is not replaced and that the
DNC file structure is modified using DNC. If inexplicable inconsistencies occur on a
regular basis, however, contact our support team.
Note
With DNC Plant, you are advised to check for consistencies and rectify these
directly on the server because the consistency check covers all the NC
administrative data for all groups and machines.
