Get port from component

Description

example

port = getPort(compObj,portName) gets the port on the component compObj with a specified name portName.

Examples

Create and connect two ports in System Composer™.

Create a top-level architecture model.

modelName = "archModel";
arch = systemcomposer.createModel(modelName,true);
rootArch = get(arch,"Architecture");                  

Create two new components.

names = ["Component1","Component2"];
newComponents = addComponent(rootArch,names);

Add ports to the components.

outPort1 = addPort(newComponents(1).Architecture,"testSig","out"); 
inPort1 = addPort(newComponents(2).Architecture,"testSig","in");

Extract the component ports.

srcPort = getPort(newComponents(1),"testSig");
destPort = getPort(newComponents(2),"testSig");

Connect the ports.

conns = connect(srcPort,destPort);

View the model.

systemcomposer.openModel(modelName);

Improve the model layout.

Simulink.BlockDiagram.arrangeSystem(modelName)

TermDefinitionApplicationMore Information
architecture

A System Composer architecture represents a system of components and how they interface with each other structurally and behaviorally. You can represent specific architectures using alternate views.

Different types of architectures describe different aspects of systems:

  • Functional architecture describes the flow of data in a system.

  • Logical architecture describes the intended operation of a system.

  • Physical architecture describes the platform or hardware in a system.

You can define parameters on the architecture level using the Parameter Editor.

model

A System Composer model is the file that contains architectural information, including components, ports, connectors, interfaces, and behaviors.

Perform operations on a model:

  • Extract the root-level architecture contained in the model.

  • Apply profiles.

  • Link interface data dictionaries.

  • Generate instances from model architecture.

A System Composer model is stored as an SLX file.

component

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:

Components
port

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:

  • Component ports are interaction points on the component to other components.

  • Architecture ports are ports on the boundary of the system, whether the boundary is within a component or the overall architecture model.

Ports
connector

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.
