DiagnosticInfoCaller

Call AUTOSAR Diagnostic Event Manager (Dem) service interface DiagnosticInfo

• 

Libraries:
AUTOSAR Blockset / Classic Platform / Basic Software / Diagnostic Event Manager (Dem)

Description

The AUTOSAR standard defines a Diagnostic Event Manager (Dem) service as a part of Basic Software (BSW) that runs in the AUTOSAR Runtime Environment (RTE). AUTOSAR software components access Dem services through client-server calls. The DiagnosticInfoCaller block calls the Dem service interface DiagnosticInfo to initiate a specified operation.

Parameters

Client port name — Name of client port AUTOSAR component uses to call Dem service interface DiagnosticInfo

DiagnosticInfo (default) | character vector

Enter the name of the client port the AUTOSAR software component uses to call the Dem service interface DiagnosticInfo.

Programmatic Use

Block Parameter: PortName

Type: character vector

Values:'DiagnosticInfo' | unique name

Default: 'DiagnosticInfo'

Operation — Specify operation defined in Dem service interface DiagnosticInfo

GetEventStatus (default) | GetMonitorStatus | GetEventFailed | GetEventTested | GetDTCOfEvent | GetFaultDetectionCounter | GetEventExtendedDataRecord | GetEventFreezeFrameData

Select the operation that the AUTOSAR software component calls from the Dem service interface DiagnosticInfo. The AUTOSAR standard defines the operations. After you select the operation, the inports and outports for the block are generated to support the operation.

Programmatic Use

Block Parameter: Operation

Type: character vector

Values: 'GetEventStatus' | 'GetMonitorStatus' | 'GetEventFailed' | 'GetEventTested' | 'GetDTCOfEvent' | 'GetFaultDetectionCounter' | 'GetEventExtendedDataRecord' | 'GetEventFreezeFrameData'

Default: 'GetEventStatus'

Data type for DTCFormat — Specify data type to represent Dem format type

Enum:Dem_DTCFormatType (default)

Specify an enumerated data type to represent a Dem format type required for some operations. For more information, see the AUTOSAR standard Specification of Diagnostic Event Manager.

Dependencies

Specify this parameter when Operation is set to GetDTCOfEvent.

Programmatic Use

Block Parameter: Datatype

Type: character vector

Values: 'Enum: Dem_DTCFormatType' | enumerated data type

Default: 'Enum: Dem_DTCFormatType'

Sample time — Block sample time

'-1' (default) | scalar

Block sample time. The default sets the block to inherit its sample time from the model.

Programmatic Use

Block Parameter: st

Type: character vector

Values: real scalar

Default: '-1'

More About

Enumerated data types Dem_DTCFormatType and Dem_EventStatusType

For some Dem operations such as GetDTCOfEvent and GetEventStatus, the block parameters dialog box displays a data type parameter. The parameter specifies an enumerated data type for a function input that represents a Dem format type or event status. Default data types Dem_DTCFormatType or Dem_EventStatusType defined by the AUTOSAR standard are provided by the software.

When you generate code for a model configured to use one of these enumerated data types then their standardized definitions are included in generated header file Rte_Type.h.

For enumerated data type Dem_DTCFormatType the generated code includes this definition:

typedef uint8 Dem_DTCFormatType;

#ifndef DEM_DTC_FORMAT_OBD
#define DEM_DTC_FORMAT_OBD             (0)
#endif

#ifndef DEM_DTC_FORMAT_UDS
#define DEM_DTC_FORMAT_UDS             (1)
#endif

#ifndef DEM_DTC_FORMAT_J1939
#define DEM_DTC_FORMAT_J1939           (2)
#endif

For enumerated data type Dem_EventStatusType the generated code includes this definition:

typedef uint8 Dem_EventStatusType;

#ifndef DEM_EVENT_STATUS_PASSED
#define DEM_EVENT_STATUS_PASSED        (0)
#endif

#ifndef DEM_EVENT_STATUS_FAILED
#define DEM_EVENT_STATUS_FAILED        (1)
#endif

#ifndef DEM_EVENT_STATUS_PREPASSED
#define DEM_EVENT_STATUS_PREPASSED     (2)
#endif

#ifndef DEM_EVENT_STATUS_PREFAILED
#define DEM_EVENT_STATUS_PREFAILED     (3)
#endif

#ifndef DEM_EVENT_STATUS_FDC_THRESHOLD_REACHED
#define DEM_EVENT_STATUS_FDC_THRESHOLD_REACHED (4)
#endif

Version History

Introduced in R2016b

R2025a: Use operations with any supported schema version

Starting R2025a, you can use any operation that is associated with the block, regardless of the configured schema version of the model and other blocks in the model.

R2024a: Use operation GetMonitorStatus

Starting in R2024a, use Diagnostic Event Manager (Dem) operation GetMonitorStatus. To use this operation your model must be mapped to an AUTOSAR component.

R2023a: Basic Software caller blocks support all AUTOSAR schema versions

Starting in R2023a, Basic Software caller (BSW) blocks support all AUTOSAR schema versions supported by AUTOSAR Blockset. The BSW blocks inherit the same schema version specified by the model. Code and ARXML generated from the component reflect the schema version specified on the model. When you change the schema version specified by the model, the software automatically replaces software calls to the correct operation.

In some cases, the software may prompt you to confirm a change when moving between schema versions. The software may also display a warning as you update to new schema versions as some modeling patterns are no longer compliant with the configured AUTOSAR schema version.
