The “Services” area provides you with an overview of all programs and data
stored on the NC, PLC, drive and hard disk. In order to view all of the directo-
ries, you must first call up the Select file display and then set the display as
required. Only then are the required data displayed.

The operating sequence for data output via the V.24 interface applies to all data.
Proceed as follows:
1. Position the cursor on the desired data
2. Press SK Data out
3. Press SK V24 or PG
4. Press SK OK
5. Read the log (only if errors occur)
It is not practical to back up all directories for a data backup via V.24. You
should only output data required for a new start-up. The streamer should be
used to create a complete copy of all data.
