Automatic data set comparison and newly created data set with manual data transfer, quick filters

IAV Macara

All those who often have to compare application data sets know that this can be a tedious task. How nice it would be if one could simply load an A2L description file and several data set files into a software and then automatically compare them all with each other. If the result is then displayed clearly and you can easily focus on the variables of interest to you using strong filters, that would be a big win.
This is what IAV Macara does.

And IAV Macara can do much more. The user can merge data from several data sets into a new data set and also make changes here, i.e. edit individual values but also characteristic curves and maps and their interpolation points. Of course, this is done in compliance with the rules described in A2L, such as hard and soft limits or interpolation point monotony. Suitable editors and graphic displays help when changing values. The created data sets can then be exported in the formats DCM, CDFX or PaCo and also loaded again.

For the use of various data sources, the cloud functionality provides access to the file system and to interfaces, e.g. to AVL Creta and Eta’s INCA database. Interested? Then contact us via email at RA Consulting is the exclusive reseller for IAV Macara.

Note: IAV Macara is currently only approved for use in the European Union.

Remote control of DiagRA D and Silver Scan-Tool via the optional Web Services API

More and more users of DiagRA D and Silver Scan-Tool are taking advantage of the remote control option via the Webservices API. Via the interface, external applications on the same computer or in the local network can use almost the complete functionality of both applications. For example, flash sequences with subsequent diagnostic tests can be automated via a Python script or special diagnostic tests on HiLs or test benches can be integrated into the experiments. Of course, recurring OBD tests can also be automated very easily.

Technical background: The interface of the web services is given by a machine-processable format, typically by WSDL (Web Services Description Language). The network protocol SOAP (Simple Object Access Protocol) is used for communication. XML is used as the message format and the HTTP protocol for communication within the network. In the case of DiagRA D/Silver Scan-Tool, communication takes place between a client programme and DiagRA D/Silver Scan-Tool, with DiagRA D/Silver Scan-Tool serving as the server application. The web services are implemented as an API for SOAP, so the user does not have to worry about creating the XML messages or HTTP communication.

The example below shows how the communication is first initiated via DiagRA D using a Python script, then all values from mode $01 are read from all OBD ECUs, then the ECU supply voltage PID $42 is specifically read, and finally the MIL status from mode $03 is read. Finally, communication with the OBD system is terminated. In the example, ZEEP is used as the SOAP client. Documentation of the commands can be found directly in existing installations of DiagRA D or Silver Scan-Tool in the Samples folder.
The Webservices plugin is an optional extension of a DiagRA D or Silver Scan-Tool licence and can either be ordered with a licence or added later.

News about DiagRA D and Silver Scan-Tool

Current versions as of December 9, 2020: 7.45.40

  • new recording format MDF4 with selectable MDF version 4.2.0, 4.1.1, 4.1.0 or 4.0.0
  • We have added DiagRA X Viewer to our download server. It is an add-on tool that can open MDF4 files created with DiagRA D’s recording function. We have decoupled it from our DiagRA X application tool for use with DiagRA D. You do not need an additional license for the viewer (just as you do for XML-Convert and XML-to-Excel).
  • The XML-to-PDF help tool has been replaced by the XML-Convert tool. The XML-to-PDF conversion function is again implemented in this new tool and in addition there is an XML-to-HTML function. The reason for this is that there are more and more problems when browsers are supposed to open XML files using a stylesheet. Just install the tool. It removes the XML-to-PDF tool and provides the same functionality plus the HTML conversion feature.
  • XML-to-Excel lets you convert OBD data from XML outputs of DiagRA D measurement runs to Excel. One can convert multiple XML files to one Excel file, simultaneously or sequentially, to compare them.
  • Adaptation work for the new SAE J1979-2 has started. We expect to provide a first version in the middle of Q1 2021.
  • Extensive enhancements for NOx binning and Green House Gas in SAE J1939 and in SAE J1979 Mode $09.

DiagRA D only

  • Support for CAN FD. Many interface types are already supported. Communication with ECUs supporting CAN FD is much faster – especially flash programming via DiagRA D Flash Plugin.
  • Autosar XML for parameterization of FlexRay communication

Also this year we were represented together with our partners Intrepid Control Systems and emotive at the Testing Expo in Stuttgart. We would like to thank all interested parties, customers, partners and (business) friends for the exciting and interesting exchange and look forward to Testing Expo 2020.

On-Board Diagnostics Symposium – Americas

This year’s symposium dealt with OBD topics for passenger cars, light and heavy commercial vehicles, but also for off-road vehicles and motorcycles. As an exhibitor, we were once again able to demonstrate our expertise. The annual event gives us the opportunity to get in personal contact with many users from all areas (OEM, suppliers and authorities) of our software DiagRA D and Silver Scan-Tool. In addition, the symposium offered us the opportunity to meet new customers, exactly those who have to deal with the OBD conformity of their vehicles or those who work on the OBD certification on behalf of the OEM.

We would like to thank everyone for the friendly and interesting discussions and suggestions.

ASAM plans cooperation with CATARC to open up Chinese market
