Configure AUTOSAR Adaptive Service Interface Identifier

Service instance identifiers, service interface identifiers, and service versioning facilitate communication and interaction between software components in service-oriented architectures. A service interface defines the type of service, and a service instance defines where a specific service is running. The service interface identifier (also known as Service ID) identifies the interface of a service, and the service instance identifier identifies a specific instance of a service.

AUTOSAR Blockset allows you to

  • Configure the service interface identifier for a deployment object corresponding to the service interface. When you build the model, this information is written to the SERVICE-INTERFACE-ID field in the generated ARXML file.

  • Define service versioning (major and minor) for the SOME/IP service interface deployment object. When you build the model, this information is written to the SERVICE-INTERFACE-VERSION field.

Configure Service ID and Define Service Versioning

These steps show how to configure the Service ID of the SOME/IP deployment object corresponding to a service port in the autosar_LaneGuidance model.

  1. Open the model.

    open_system("autosar_LaneGuidance");

  2. Create an AUTOSAR properties object for the model.

    apiObj = autosar.api.getAUTOSARProperties("autosar_LaneGuidance");

  3. Set the network binding for the model to SOME/IP.

    apiObj.set("XmlOptions","NetworkBinding","SOME/IP");

  4. Find the paths for the deployment objects corresponding to the SOME/IP network binding.

    paths = apiObj.find('/','SomeipServiceInterfaceDeployment', ...
    'PathType','FullyQualified')

  5. Set a Service ID, major version, and minor version for the provided port or required port.

    apiObj.set(paths{1},"ServiceInterfaceId",11);
apiObj.set(paths{1},"MajorVersion",101);
apiObj.set(paths{1},"MinorVersion",102);

  6. Save and build the model.

The model build process writes the specified service interface identifier to the SERVICE-INTERFACE-ID field and service interface deployment versions to the SERVICE-INTERFACE-VERSION field in the generated autosar_LaneGuidance_ServiceInstanceManifest.arxml
