User Data Backup/Series Machine Start-Up

Explanations on data backup
User data are called all data or data areas that can be entered by the user to
achieve the specific functionality of the SINUMERIK 840Di or the
SIMODRIVE 611 universal drives.
In the case of a data backup, e.g. after start-up of the control system, the user
data selected through the user interface are written to a so-called series ma-
chine start-up file.
After the series machine start-up file has been read in, the control system is in
its original status again as it was at the time of data backup.
The past has shown that the following times are recommended to carry out data
backups:
S
After start-up,
S
After changing machine-specific settings,
S
In service cases (e.g. after a hardware replacement, software upgrade, etc.),
to resume production without longer downtimes.
Before activating memory-configuring machine data (a warning appears), a data
backup must be carried out.
A data backup can currently not yet be carried out uniformly for all components
(SINUMERIK 840Di-NC, PLC, HMI Advanced (option) and SIMODRIVE 611
universal).
A data backup must therefore be carried out separately for the following compo-
nents:
S
NC, PLC and HMI Advanced (option)
S
SIMODRIVE 611 universal.
The data backup with respect to the NC, PLC and HMI Advanced (option) user
data is carried out with
S
SinuCom NC (part of the SINUMERIK 840Di installation)
S
HMI Advanced (option).
