Note The use of To xPC Target blocks require a connection between the host
and target PC. If there is no connection between the host and target PC,
operations such as opening a model that contains these blocks or copying
these blocks within or between models, will take significantly longer than
normal.
Block Parameters
xPC Target application name — The function xpcsliface automatically
enters a name entry for this parameter. It is the same name as the Simulink
model that xPC Target uses to build the target application.
Path to block in model running on xPC target — The function xpcsliface
automatically enters an entry for this parameter and uses it to access the block
identifier.
Parameter name — The function xpcsliface automatically determines the
entry for this parameter and enters it. Note that the parameter name might
not match the label name for that parameter in the Block Parameters dialog
box. For example, the label name for a gain block is
Constant value, but the
parameter name is
Value.
From xPC Target Block
This block behaves like a source and its output is usually connected to the input
of a display device.
Because only one numerical value per signal is uploaded during a time step,
the number of samples of a scope object is set to 1. The block uses the signal
tracing capability of the xPC Target command-line interface and is
implemented as an M-file S-function. This block is available from the
