Find if element has property
Find Property on Component
weight property from a component with the
sysComponent stereotype applied.
Create a model with a component called
model = systemcomposer.createModel("archModel",true); arch = get(model,"Architecture"); comp = addComponent(arch,"Component");
Create a profile with a stereotype and a property, then apply the profile to the model.
profile = systemcomposer.profile.Profile.createProfile("sysProfile"); base = profile.addStereotype("sysComponent"); base.addProperty("weight",Type="double",DefaultValue="10",Units="g"); model.applyProfile("sysProfile")
Apply the stereotype to the component, then set a new weight property.
Find if the weight property exists on the component.
result = hasProperty(comp,"sysProfile.sysComponent.weight")

A System Composer™ architecture represents a system of components and how they interface with each other structurally and behaviorally.
Different types of architectures describe different aspects of systems. You can use views to visualize a subset of components in an architecture. You can define parameters on the architecture level using the Parameter Editor.
A System Composer model is the file that contains architectural information, including components, ports, connectors, interfaces, and behaviors.
Perform operations on a model:
A System Composer model is stored as an SLX file.
|Create Architecture Model with Interfaces and Requirement Links|
A component is a nontrivial, nearly independent, and replaceable part of a system that fulfills a clear function in the context of an architecture. A component defines an architectural element, such as a function, a system, hardware, software, or other conceptual entity. A component can also be a subsystem or subfunction.
Represented as a block, a component is a part of an architecture model that can be separated into reusable artifacts. Transfer information between components with:
A port is a node on a component or architecture that represents a point of interaction with its environment. A port permits the flow of information to and from other components or systems.
There are different types of ports:
Connectors are lines that provide connections between ports. Connectors describe how information flows between components or architectures.
A connector allows two components to interact without defining the nature of the interaction. Set an interface on a port to define how the components interact.
A stereotype is a custom extension of the modeling language. Stereotypes provide a mechanism to extend the architecture language elements by adding domain-specific metadata.
Apply stereotypes to model elements such as root-level architecture, component architecture, connectors, ports, data interfaces, value types, functions, requirements, and links. Functions only apply to software architectures. You must have a Requirements Toolbox™ license to apply stereotypes to requirements and links. A model element can have multiple stereotypes. Stereotypes provide model elements with a common set of property fields, such as mass, cost, and power.
|Extend Architectural Design Using Stereotypes|
A property is a field in a stereotype. You can specify property values for each element to which the stereotype is applied.
Use properties to store quantitative characteristics, such as weight or speed, that are associated with a model element. Properties can also be descriptive or represent a status. You can view and edit the properties of each element in the architecture model using the Property Inspector.
A profile is a package of stereotypes that you can use to create a self-consistent domain of element types.
Author profiles and apply profiles to a model using the Profile Editor. You can store stereotypes for a project in one or several profiles. When you save profiles, they are stored in XML files.
|interface data dictionary|
An interface data dictionary is a consolidated list of all the interfaces and value types in an architecture and where they are used.
Local interfaces on a System Composer model can be saved in an interface data dictionary using the Interface Editor. You can reuse interface dictionaries between models that need to use a given set of interfaces, elements, and value types. Linked data dictionaries are stored in separate SLDD files.
A data interface defines the kind of information that flows through a port. The same interface can be assigned to multiple ports. A data interface can be composite, meaning that it can include data elements that describe the properties of an interface signal.
Data interfaces represent the information that is shared through a connector and enters or exits a component through a port. Use the Interface Editor to create and manage data interfaces and data elements and store them in an interface data dictionary for reuse between models.
A data element describes a portion of an interface, such as a communication message, a calculated or measured parameter, or other decomposition of that interface.
Data interfaces are decomposed into data elements:
A value type can be used as a port interface to define the atomic piece of data that flows through that port and has a top-level type, dimension, unit, complexity, minimum, maximum, and description.
You can also assign the type of data elements in data interfaces to value types. Add value types to data dictionaries using the Interface Editor so that you can reuse the value types as interfaces or data elements.
|Create Value Types as Interfaces|
An owned interface is an interface that is local to a specific port and not shared in a data dictionary or the model dictionary.
Create an owned interface to represent a value type or data interface that is local to a port.
|Define Owned Interfaces Local to Ports|
An adapter helps connect two components with incompatible port interfaces by mapping between the two interfaces. An adapter can act as a unit delay or rate transition. You can also use an adapter for bus creation. Use the Adapter block to implement an adapter.
With an adapter, you can perform functions on the Interface Adapter dialog box:
A physical subsystem is a Simulink® subsystem with Simscape™ connections.
A physical subsystem with Simscape connections uses a physical network approach suited for simulating systems with real physical components and represents a mathematical model.
|Implement Component Behavior Using Simscape|
A physical port represents a Simscape physical modeling connector port called a Connection Port (Simscape).
Use physical ports to connect components in an architecture model or to enable physical systems in a Simulink subsystem.
|Define Physical Ports on Component|
A physical connector can represent a nondirectional conserving connection of a specific physical domain. Connectors can also represent physical signals.
Use physical connectors to connect physical components that represent features of a system to simulate mathematically.

A physical interface defines the kind of
information that flows through a physical port. The same interface can be assigned to multiple
ports. A physical interface is a composite interface equivalent to a
