Data backup
16.10 Network settings
Basic procedure
● Backup of network settings
After activation, the network settings can also be backed up when a commissioning archive
is created when a check mark is set, see Creating a start-up archive (Page 356).
● Importing network settings
The saved archives can be imported in the same manner as a commissioning archive, see
Reading-in a start-up archive (Page 359).
Note
Importing network settings for replacement components
Disconnect the replacement components from the system network before you import the
saved network settings.
NCU
Only the NCU settings are saved with the HMI on the NCU. The following data is backed up:
● /user/system/etc/basesys.ini
● /user/common/tcu (complete directory)
The network settings of an NCU can be backed up and read only from an HMI on the PC/PG.
This means the NC address in mmc.ini on the PC/PG is always 192.168.215.1.
PCU
PCU and, if applicable, NCU settings saved with the HMI on the PCU. The following data is
backed up:
● PCU
– /user/system/etc/basesys.ini
– mmc.ini for SINUMERIK Operate
● NCU (when present as master)
– /user/system/etc/basesys.ini
– /user/common/tcu (complete directory)
The following archives are created: Archivename_pcu.arc and Archivename_ncu.arc
Importing an archive for a configuration with NCU as master (DHCP) and PCU (on_low):
1. Import the archive for Archivename_pcu.arc on a PCU with SINUMERIK Operate.
2. Depending on the replaced parts of the NCU, note the following:
– If the NCU was not replaced, the system restarts.
– The NCU has been replaced, Archivename_ncu.arc must be imported via the X127
370
interface with a separate HMI.
