Although the file system is case insensitive, the case is preserved to maintain file
checksums. The compact flash directory only appears when the compact flash is
inserted into the system. To reference files on the compact flash, prefix the "\CFØ\"
to any fully qualified path from the Windows environment. For example, if the file in
Windows is "\MyDirectory\MySubdirectory\MyFile.ext", the complete 2-Series path
for a file on the first Compact Flash slot (onboard) is:
"\CFØ\MyDirectory\MySubdirectory\MyFile.ext"
You do not have to create subdirectories for general files; you can put them in the
root of the Compact flash (\CFØ).
The only time subdirectories are required is when putting bootable projects on the
Compact Flash (\CFØ\SIMPL, \CFØ\SPLUS), but SIMPL Windows takes care
of that for you when you do the File | Copy to CF function. SIMPL Windows
makes the appropriate subdirectories. The same is true when you put web pages on
the Compact Flash. The tools create the appropriate directories.
Flash
The 4MB flash memory consists of approximately 1.5MB used for firmware, and
approximately 2.5MB available for SIMPL and SIMPL+
flash conform to a flat directory structure.
1. SIMPL+ Modules.
2. SIMPL Program.
3. Operating System.
Non-volatile (NVRAM)
1. SIMPL+ Variables (using "nonvolatile" qualifier or
#DEFAULT_NONVOLATILE).
2. Signals explicitly written to NVRAM (by symbols such as Analog RAM,
Analog RAM from database, Serial RAM, Serial RAM from database,
Analog Non-volatile Ramp, Digital RAM, etc.).
3. Portions of the NVRAM may be set aside for implementing an "NVRAM
Disk". This can be used to provide file system access from SIMPL+.
