Upgrading

Upgrade options
You have the following options of upgrading the CNC software:
● Automatic upgrade using USB-FlashDrive
● Upgrade using USB-FlashDrive
● Upgrade using WinSCP on PG/PC
● Upgrade using VNC Viewer on PG/PC
Note
An upgrade is possible as of CNC software 2.xx. An upgrade from other software versions
is not permitted. In this case, a new installation is required.
Before the upgrade, you can backup the complete CompactFlash card. Using Restore, you
can write back this backup to the CompactFlash card.
Data backup before upgrades
Carry out a data backup before each upgrade:
● Commissioning archive of NC/PLC/drive data
● Load the PLC project into the PC/PG (STEP 7)
● License key
When the software is upgraded, all user data is kept on the CompactFlash card in the
directories /user, /addon, /oem. The license key is kept as well.
Prior to overwriting a licensed CompactFlash card, a backup of the license key is absolutely
necessary. The key is available in file 'keys.txt' and is stored under the path keys/sinumerik.
The backup of the key can be performed, for example, with WinSCP, from the PG/PC.
Note
The licenses are permanently assigned to the CompactFlash card (card ID) and can only be
used on this card.
The license key can be read back via Web License Manager (Page 45) using the card number.
Automatic upgrading
For an automatic upgrade with autoexec.sh from the USB-FlashDrive, the CompactFlash card
is first backed up.
The backup file "card_img.tgz" is saved under the following directory:
/machines/[machine name+serial number of the CompactflashCard]
