DNC Plant/DNC Cell (FBDN1)
4 NC data management

4.2 Download/upload functions

General
In the case of machines connected serially, the interface is only opened for the
download/upload procedure and is then closed again. This means that the same
serial interface can be used for different machines (e.g. when DNC is installed on a
mobile station).
Authorization to download/upload NC data must be assigned to the relevant users
(see also: Chapter 5 - User administration).
Note
The interface is always open if the dialog function is configured. It can, therefore,
only be used for one CNC machine tool.
Marking
A yellow arrow on the user interface on the machine indicates when data is being
downloaded/uploaded.

Note
When a download/upload procedure is initiated, it can take a while for the yellow
arrow to appear.
This can be due to a number of reasons, such as the conversion of end-of-line
characters or code or the insertion of spacers. It can also be due to the size of the
file or the computing power.
