MVCI D-Server<br />
• The D-Server is an object-oriented<br />
programming interface for applications<br />
D-PDU API (ISO 22900-2)<br />
written in C/C++ or Java<br />
• The D-Server provides an interface for diagnostic <strong>sequence</strong>s (e.g. for<br />
reprogramming) written in JAVA („JAVA jobs“)<br />
• The D-Server contains a JAVA Job proccessor for the execution oif JAVA Jobs<br />

JAVA Jobs & JRE<br />
Official statement of the automotive industry:<br />
„Since the D-Server API is subject to change and since there is no guarantee that<br />
successive versions of java runtime environments (JRE) used by D-Server<br />
components support JAVA byte code gen erated for previous JRE-versions, longterm<br />
compatibility of Java code is not assured.“<br />
Short Version: „JAVA is not under OEM control…“<br />
Solution: Create a standardized XML <strong>based</strong> data <strong>exchange</strong> <strong>format</strong> for the<br />
documentation and machine-readable description of diagnostic <strong>test</strong> <strong>sequence</strong>s.<br />

ISO 13209 (<strong>OTX</strong>)<br />
• ISO 13209: Road vehicles – Open Test <strong>sequence</strong> eXchange <strong>format</strong> (<strong>OTX</strong>)<br />
consists of three parts:<br />
• -1 (PRF) General in<strong>format</strong>ion and use cases<br />
• -2 (DIS) Core data model specification and requirements<br />
• -3 (DIS) Standard extensions and requirements<br />
ISO 13209 specifies a standardized XML <strong>based</strong> data <strong>exchange</strong> <strong>format</strong> for the<br />
documentation and machine-readable description of diagnostic <strong>test</strong><br />
<strong>sequence</strong>s.<br />

<strong>OTX</strong>-Runtime on D-Server API<br />
• An <strong>OTX</strong> runtime is necessary to process the binary equivalent of the <strong>OTX</strong> data<br />
• If the <strong>OTX</strong> database contains <strong>test</strong> <strong>sequence</strong>s that are solely <strong>based</strong> on diagnostic<br />
communication (e.g. for flash-reprogramming), the MVCI D-Server is used to<br />
process the data<br />
