Simulation, Development and Test of ISO11783 Systems

The simulation of individual attachments is simplified greatly through specific functionality. The different network nodes are simulated by the ISO11783 interaction layer based on the communication relationships in the database. This means that the network management, the transfer of the object pool to the VT and the transfer of the device description to the task controller are already taken care of – without a single line of code. Measurement data requested by the task controller is also provided automatically by the interaction layer. For further functions, such as application-specific processing of user input via the VT, there is a ISO11783 library for the CAPL programming language available.

TIM Server and TIM Client

With the CANoe.ISO11783 you can simulate both the TIM Server and the TIM Client. The ISO11783 Interaction Layer provides a comprehensive set of CAPL functions for this purpose, which make it possible to configure a TIM simulation as required. Among other things, the following is possible:

• configuring AEF certificates, CRL and keys,
• simulation of user input and control of TIM functions,
• error injection.

Specialized filters and intelligent interpretation in the trace window enable a clear and informative presentation of the message flow.

Sequential execution of test units and evaluation of the results in the CANoe Test Report Viewer

CANoe .ISO11783 provides several libraries with which each ISOBUS-relevant component can be simulated. All these libraries can be easily integrated into a test environment (such as vTESTstudio). Thanks to a comfortable programming interface, no detailed knowledge of the ISO11783 specification is necessary for the test development.

From the individual test cases, any complex tests can be compiled. Test results are presented in a clear way, causes of the failure are explained in detail.

ISO11783 specific windows for diagnostic

The components DTC Monitor and Diagnostic Memory Accesswindow make it easy to work with the diagnostic protocol defined in ISO 11783-12.

• DTC Monitor
  With the DTC Monitor in the Measurement Setup you can easily display and request error codes (DTC – Diagnostic Trouble Codes) and diagnostic messages. With the support of Freeze Frames (extended information from fault memory) you can use the DTC Monitor for emission related or power train diagnostics.
• Diagnostic Memory Access
  With the Diagnostic Memory Access (DiagMemAcc) in the Measurement Setup you can read and write parts of the memory as well as execute a boot load procedure. For this the diagnostic messages DM14, DM15, DM16, and DM18 are used.

For OEM-specific diagnostic protocols, the Diagnostic Feature Set (KWP2000 and UDS) is available. This enables support of networks with dynamic ECU addresses as well.
