1 Target and Scop e Objects
sample time is 0.005, the scope will acquire five identical samples for this
signal,andthenthenextfiveidenticalsamples,andsoon.
Understanding the structure of scope objects will help you to use the MATLAB
command-line interface to view and collect signal data.
Refer to Chapter 1, “Target and Scope Objects” for a description of h ow to use
these objects, properties, and methods.
A scope object on the host PC represents a scope on the target PC. You use
scope objects to observe t he signals from your target application d uring a
real-time run or analyze the data after the run is finished.
Tocreateascopeobject,
• Add an xPC Target scope block to your Simulink model, build the model to
create a scope, and then use the target object method
getscope to create a
scope object.
• Use the target object method
addscope to create a scope, create a scope
object, and assign the scope properties to the scope object.
A scope object has associated properties and methods specific to that object.
To read about scope object types, see “Scope Object Types” on page 1-4.
ScopeObjectTypes
You can create scopes of type target, host,orfile. Upon creation, The
xPC Target software assigns the appropriate scope object data type for the
scope type:
•
xpctarget.xpcsctg for scopes o f type target
• xpctarge t.xpcschost fo r scopes of typ e host
• xpctarge t.xpcfs for scopes of type fil e
• xpctarge t.xpcsc encompasses the object properties common to all the
scope object data t ypes . T he xPC Target software creates this object if you
create multiple scopes of different types for one model and combine those
scopes, for ex ample, into a scope vector.
