Redirecting Files to
Other File Groups
GID1 is the default system mode setting for performing downloads. Using the
system mode menu options, you can select another file group (GID 2–15) as the
target group for the application download. If you select another group, files
download directly into the SRAM of that file group.
To redirect files from the selected target file group to another file group as part of
the download operation, insert a zero-length SETGROUP.n file in the batch
download list (the same as SETDRIVE.x). The syntax of this convention is
SETGROUP.n, where n = 1–15 for GIDs 1–15.
To create a zero-length SETGROUP file on the download computer, use the DOS
command REM as in the following example:
REM >SETGROUP.2
If you do not insert SETGROUP.n special files into the download list, all files
download into the target group selected in system mode. If no number is added to
the SETGROUP filename, SETGROUP.1 (GID1) is assumed.
Restrictions on File
Redirection
The V
x
810 file system restricts how you can redirect files to other file groups. Here
are the important points to remember:
•
The main application must always be downloaded onto GID1.
•
Because of the way file groups are managed in the V
x
810 file system, only two
schemes are available for redirecting files during a batch application
download:
•
If using system mode menu options, select Group 1 (default) as the target
group for the download; files can be redirected to any other file group,
including GID15.
•
If using system mode menu options, select a file group other than Group 1
(GIDs 2–14) as the target group for the download; files can be redirected
only into the selected file group or into GID15.
In the following example, GID1 is selected as the target group for the download.
The download list loads FOO.OUT into Group 1 SRAM, GOO.OUT into GID2, and
COMN.LIB shared library into GID15. When the device restarts after the
download, the file authentication module is invoked for all three files, based on the
certificate data that authorizes them to be stored in their respective file groups.
