4.6

BACKUP with Valitek streamer/PC link

The function BACKUP backs up all the data on the hard disk using a VALITEK
streamer/PC link, i.e. the system software (SIEMENS), the user software (e.g.
customer UMS), part programs and machine data are all stored on a magnetic
tape cartridge or external PC.
Up to SW 1 it is not possible to store any user data using the VALITEK streamer
(hardware option). With SW 2 and higher user data can be stored separately.
It is necessary to perform a BACKUP after every start-up, otherwise all data
would be lost if there were a fault on the MMC CPU! The choice of VALITEK
streamer or PC link can be made via the menu Set I/O device.
Installation of the VALITEK streamer:
The VALITEK streamer can only be connected to the parallel interface (CEN-
TRONICS interface) of the MMC CPU with Siemens cable 6FC9 344–4XV. It is
not possible to connect another streamer because the software is only suitable
for the VALITEK streamer.

Caution!
The software for the BACKUP function is suitable for use
with the VALITEK streamer or PC link.
Caution! For Valitek streamers only!
Save system data and user data on separate cartridges
since backup overwrites any data already existing on the
cartridge.
If you connect to the interface SERIAL1 or SERIAL2 in-
stead of the interface PARALLEL1, you will destroy the
MMC CPU!
