Call AUTOSAR Diagnostic Event Manager (Dem) service interface DiagnosticMonitor

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

  • DiagnosticMonitorCaller block


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 DiagnosticMonitorCaller block calls the Dem service interface DiagnosticMonitor to initiate a specified operation.

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