-46 SINUMERIK 840Di System Overview (SYI) - 02.2001 Edition
Non-Siemens drives
If drives from competitors are used, the sole responsibility for the start-up and
integration lies with the OEM or the user.
5.3 Service information
To record and visualize service information, the SINUMERIK 840Di keeps a
continuos log book recording all events pertaining to the NC and PLC. These are,
e.g.:
• Installation of NC and PLC software updates
• Messages with regard to the NC/PLC SRAM data handling
• Exceeding of temperature limit values
• Voltage dips and power failure events
5.4 Data backup
For reasons of the general data integrity, the hard disk of the SINUMERIK 840Di
has been divided into 4 different partitions with the following contents:
• 1st partition / drive C: MS DOS 6.2, Service menu
• 2nd partition / drive D: contains, e.g. the "Images" directory with the
preinstalled and self-created images
• 3rd partition / drive E: Windows NT 4.0
• 4th partition / drive F: SINUMERIK 840Di system software and possibly further
Windows NT applications, such as SIMATIC STEP7, OEM applications, etc.
For user-friendly and comprehensive data backup and recovery, the SINUMERIK
840Di includes the Service menu (MS-DOS application created by Siemens and
the backup software Norton Ghost already in the standard version.
Using the Service menu, the data to be saved, individual partitions or even the
entire hard disk are selected with menu assistance, and the backup software is
parameterized. Norton Ghost will then create the appropriate, naturally packed
images. These can be transferred either to an external computer or be stored
locally on the hard disk of the PCU.
In case of servicing, for test purposes or during the start-up, the images can be
reloaded to the hard disk of the PCU via the Service menu, thus providing an
optimum and consistent handling of large data volumes.
