12.4.3 SINUCOPY–FFS (SW 4.4 and higher)
The SINUCOPY–FFS program can be used to read or write either the SINUM-
ERIK system software (NC) or a flash file system (FFS) from or to NC cards of
the NCU installed on a PC with an active PCMCIA slot.
A flash file system is similar to a DOS data storage medium, such as a floppy
disk. The system must be formatted before data can be stored. Directory struc-
tures can then be created and files stored in any format.
The data storage medium is an electrically erasable EPROM. That means that
the corresponding area always has to be deleted before data are written. Algo-
rithms adapted in accordance with the block identification are required in order
to delete and write data. You can determine the speed of data write transfers to
a large extent.
An FFS system can usually be read directly by DOS/WINDOWS. Since the
NC system software, which is not saved in FFS format, is also stored on the
card, this is only possible with SINUCOPY–FFS.
S The following PCMCIA card drivers/hardware are supported:
– CSM OMNI97 (external PCMCIA device operated on the parallel inter-
face of the PC)
– PG740 /PG720C (with CSM driver CISIO–S)
– Laptops with PCMCIA slots (with Intel driver ICARDRV3 – only for cards
up to 4 MB)
– CSM PCJB slots (only for cards up to 4 MB)
S The program will run under Windows 95. If CSM OMNI97 is used, it will also
run under Windows NT.
SINUCOPY–FFS can manipulate the FFS area of the NC card using the follow-
ing functions, independent of the SINUMERIK system software (NC):
S Read
S Modify
S Write new data
S Reformat
S Create new directories
S Copy a file into the directories and subdirectories
S Read and write system software
