Introduction
You can access signal data files, or any target PC system file, in one of the
following ways:
• If you are running the target PC as a stand-alone system, you can access
that file by rebooting the target PC under an operating system such as DOS
and accessing the file through the operating system utilities.
• If you a re running the target PC in conjunction with a host PC, y ou
can access the target PC file from the host PC by representing that
file as an
xpctarget.ftp object. Through the MATLAB interface, use
xpctarget.ftp methods on that FTP object. The xpctarget.ftp object
methods are file transfer operations such as
get and put.
• If you are running the target PC in conjunction with a host PC, you can
access the target PC file from the host PC by representing the target PC file
system as an
xpctarget.fs object. Through the MATLAB interface, use
the
xpctarget.fs methods on the file system and perform file system-like
methods such as
fopen and fread on the signal data file. These methods
workliketheMATLABfileI/Omethods.The
xpctarget.fs methods also
include file system u tilities that allow you to collect target P C file system
information for the disk and disk buffers.
This topic describes procedures on how to use the
xpctarget.ftp and
xpctarget.fs methods for comm on operations. See “Function Reference” and
“Functions” for a reference of the methods for these objects.
Note This topic focuses primarily on working with the targ et PC data files
that you generate from an xPC Target scope object of type
file.
For a demo of how to perform data logging with file scopes, see Data Logging
With a File Scope.
