Motivation for MBtech today

Feedback from the ETSI perspective Can you imagine working with it? What is missing? What would you expect? Maybe: What are the differences between automotive testing and

telecommunication?

Potential Usability-Test-Persons Get a more detailed feeling for OTX Find out if it would meet your needs or which parts don’t Give detailed input about your design perspective Yes? Contact me!! Stefanie.goetzfried@mbtech-group.com

1. OTX – former motivationOTX is an exchange format for diagnostic sequences which are widely used within the automotive industry for diagnostics, testing and reprogramming of electronic components and systems in vehicles. (Schluesener, Preuschoff, Frisch 2009:92)

Strategic focus on diagnostic domain

OTX-Properties Core data model + Extensions

(e.g. Diagnose-Communication, HMI-Control) Extension Mechanism enables further extensions Unified, formal, machine readable markup-language Abstract description guarantees reusability

Initiator: Daimler, Bosch, VW

Motivation: Different platforms/systems in

different states of automotive lifecycle No exchange possibilities for so called

“Prüfabläufe” (diagnostic-sequences) HiL testing of diagnostic sequences

2. OTX – status

20.12.2008 New Work Item Proposal / ISO (Number 13209)Task Force 14 within ISO/TC22/SC3/WG1-Data CommunicationWill be submitted as a draft international standard by the End of February 2012Current version of the schema is 0.9.5 ISO 13209 (URL: http://www.iso.org/iso/catalogue_detail.htm?csnumber=53507) Part 1: Use Cases

This is part of the preamble and has essentially remained unchanged for the past 18 months

Part 2: Core Data ModelThis has already been submitted for draft international standard

Part 3: Standard InterfacesThis is the last remaining part, and is expected to be submitted by end of February.

3. OTX – future expectations

OTX (Open Test eXchange) format is an emerging ISO standard (ISO 13209) for exchanging vehicle test sequence information that promises to streamline the test authoring process and promote reuse across organizations within your company and between OEMs, suppliers and 3rd party maintenance providers.(URL: http://www.otxcentral.com/OTX-blog/bid/51894/View-Recording-of-Introductory-Webinar-on-OTX (2011))

Broadening strategic focus: not only diagnostic domain!

7. OTX – markup characteristics

Electronics Tools & EquipmentOTX: Open Test sequence eXchange

XML based language Platform independent Great number of off-the-shelf solutions World-wide accepted No own grammar neededSyntax of OTX described in XML Schema Definitions (XSD) One XSD for the core and each Extension Easy validity checking Well defined extension mechanismSemantic description of the elements unspecified Left to Extension provider Core and Standard Extensions use structured prose

Intention: No manual writing of OTX documents, but graphical composing

8. OTX – Example

Electronics Tools & EquipmentOTX: Open Test sequence eXchange

const int UPPER_BOUND = 10;

public procedure main() { int sum = 0; int counter = 0; for counter = 0 to UPPER_BOUND { sum = sum + counter; } showMessageBox("The sum is", toString(sum));}

Benefits by using OTX:

You can easily exchange your test sequences with Tiers and other suppliers “I want these tests to work!” (without exchanging the code)You give your own test-engineers the possibility to choose between graphical or script implementationYou do not depend on expert programmers anymore

Independent from the concrete realization: you can either translate it into C#, Java …or execute it directly (native execution)Abstract description guarantees reusability
