Call AUTOSAR Diagnostic Event Manager (Dem) service interface
AUTOSAR Blockset / Classic Platform / Basic Software / Diagnostic Event Manager (Dem)
For the AUTOSAR Classic Platform, the AUTOSAR standard defines important services as part of Basic Software (BSW) that runs in the AUTOSAR Runtime Environment (RTE). Examples include services provided by the Diagnostic Event Manager (Dem), the Function Inhibition Manager (FiM), and the NVRAM Manager (NvM). In the AUTOSAR RTE, AUTOSAR software components typically access BSW services by using client-server communication.
To support system-level modeling and simulation of AUTOSAR components and services, AUTOSAR Blockset provides an AUTOSAR Basic Software block library. The library contains preconfigured blocks for modeling component calls to AUTOSAR BSW services and reference implementations of the BSW services.
The DiagnosticEventAvailableCaller block calls the Dem service interface
EventAvailable to initiate the
SetEventAvailable operation. A component uses
SetEventAvailable to temporarily disable and enable a specific
event, for example, an event of the same name associated with an existing Dem
SetEventStatus caller block. Typically you connect a true/false
Boolean constant block to the
SetEventAvailable input, so that you
can switch the event off (false) or on (true). When disabled, the event fired by the
SetEventStatus block has no effect.
Client port name — Name of client port AUTOSAR component uses to call Dem service interface
EventAvailable (default) | character vector
Enter the name of the client port the AUTOSAR software component uses to call the
Dem service interface
Operation — Specify operation defined in Dem service interface
This block supports the Dem operation
generates inports and outports for the operation. You can use this operation to
configure events as unavailable. An unavailable event is treated as if it is not
configured in the system and returns E_NOT_OK when accessed by other operations.
The Operation parameter must be set to an operation supported by the schema currently specified by the model. The list of operations on the block parameters dialog reflects the operations supported by the current schema.
Sample time — Block sample time
-1 (default) | scalar
Block sample time. The default sets the block to inherit its sample time from the model.

Version HistoryIntroduced in R2020a
R2023a: Basic Software caller blocks support all AUTOSAR schema versions
Starting in 23a, 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.
