addPhysicalInterface

Create named physical interface in interface dictionary

Since R2021b

Syntax

interface = addPhysicalInterface(dictionary,name)

Description

interface = addPhysicalInterface(dictionary,name) adds the physical interface specified by the name name to the interface dictionary dictionary.

To remove an interface, use the removeInterface function.

Examples

Add Physical Interface

Create a data dictionary, then add a physical interface newInterface.

dictionary = systemcomposer.createDictionary("new_dictionary.sldd");
interface = addPhysicalInterface(dictionary,"newInterface")

Create a new model and link the data dictionary. Then, open the Interface Editor to view the new interface.

arch = systemcomposer.createModel("newModel",true);
linkDictionary(arch,"new_dictionary.sldd");

Input Arguments

dictionary — Data dictionary

dictionary object

Data dictionary, specified as a systemcomposer.interface.Dictionary object. You can specify the default data dictionary that defines local interfaces or an external data dictionary that carries interface definitions. If the model links to multiple data dictionaries, then dictionary must be the dictionary that carries interface definitions. For information on how to create a dictionary, see createDictionary.

name — Name of new physical interface

character vector | string

Name of new physical interface, specified as a character vector or string. This name must be a valid MATLAB^® identifier.

Example: "newInterface"

Data Types: char | string

Output Arguments

interface — New physical interface

physical interface object

New physical interface, returned as a systemcomposer.interface.PhysicalInterface object.

Term	Definition	Application	More Information
physical subsystem	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
physical port	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
physical connector	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.	Architecture Model with Simscape Behavior for a DC Motor
physical interface	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 Simulink.ConnectionBus object that specifies any number of Simulink.ConnectionElement objects.	Use a physical interface to bundle physical elements to describe a physical model using at least one physical domain.	Specify Physical Interfaces on Ports
physical element	A physical element describes the decomposition of a physical interface. A physical element is equivalent to a Simulink.ConnectionElement object.	Define the Type of a physical element as a physical domain to enable use of that domain in a physical model.	Describe Component Behavior Using Simscape

Term	Definition	Application	More Information
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.	Manage Interfaces with Data Dictionaries Reference Data Dictionaries
data interface	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.	Create Architecture Model with Interfaces and Requirement Links Define Port Interfaces Between Components
data element	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: Pins or wires in a connector or harness. Messages transmitted across a bus. Data structures shared between components.	Create Interfaces Assign Interfaces to Ports
value type	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
owned interface	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
adapter	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: Create and edit mappings between input and output interfaces. Apply an interface conversion UnitDelay to break an algebraic loop. Apply an interface conversion RateTransition to reconcile different sample time rates for reference models. Apply an interface conversion Merge to merges two or more message or signal lines. When output interfaces are undefined, you can use input interfaces in bus creation mode to author owned output interfaces.	Interface Adapter Adapter
