xPC Target Embedded Option Modes
The xPC Target Embedded Option extends the xPC Target base product with
two modes:
• DOSLoader — Use this mode of operation to start the kernel on the target
PC from a 3.5 inch disk, flash disk, or a hard disk. After the target PC boots
with the kernel, it waits for the host computer to download a real-time
application. You can control the target application from either the host PC or
the target PC. See “DOSLoader Mode Overview” on page 4-4 for further
details.
• StandAlone — Use this mode to load the target PC with both the xPC Target
kernel and a target application. Like DOSLoader mode, this mode of
operation can start the kernel on the target PC from 3.5 inch disk, flash disk,
or hard disk. After starting the kernel on the target PC, StandAlone mode
can also automatically start the target application that you loaded with the
kernel. Thus, this configuration provides complete stand-alone operation.
StandAlone mode eliminates the need for a host PC and allows you to deploy
real-time applications on target PCs. See “StandAlone Mode Overview” on
page 4-6 for further details.
Regardless of the mode, you initially boot your target PC with DOS from any
boot device, then the xPC Target kernel is started from DOS. xPC Target only
needs DOS to boot the target PC and start the xPC Target kernel. DOS is no
longer available on the target PC unless you reboot the target PC without
starting the xPC Target kernel.
Note The xPC Target Embedded Option requires a boot device with DOS
installed. It otherwise does not have any specific requirements as to the type
of boot device. You can boot xPC Target from any device that has DOS
installed. DOS software and license are not included with xPC Target or with
the xPC Target Embedded Option.
Without the xPC Target Embedded Option, you can only download real-time
applications to the target PC after booting the target PC from an xPC Target
boot disk. You must use a target PC equipped with a 3.5 inch disk drive.
