9.0.3 File structure in the robot controller mass storage memory
Files in root
directory, hd0a
The root directory of the mass storage memory is called hd0a. This includes several compo-
nents:
Directories and
subdirectories
Each system directory holds a number of subdirectories, defining for instance language,
options, robots, etc.
"Home" directory The system directory is the "home" directory for the system. When using the address "home:"
in the RAPID program, this directory will be addressed.
"Bin"
subdirectory
The subdirectory bin, containing the storage area for all system data, e.g. at power break. This
means that at warm start, in addition to restoring the operating system from the control system
package, all system data is restored from this directory and reloaded into the working mem-
ory.
Never change
these directories!
Never delete or change the \bin or BootRom.sys directories in the root directory. If this is
done, the controller cannot be restarted and the mass storage memory will be impossible to
use.
