The work of preparing International Standards is normally carri
11、ed out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. I
12、SO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare Internati
13、onal Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the el
14、ements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13209-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. ISO 13209 consists of the fo
15、llowing parts, under the general title Road vehicles Open Test sequence eXchange format (OTX): Part 1: General information and use cases Part 2: Core data model specification and requirements Part 3: Standard extensions and requirements ISO 13209-2:2012(E) vi ISO 2012 All rights reserved Introductio
16、n Diagnostic test sequences are utilized whenever automotive components or functions with diagnostic abilities are being diagnosed, tested, reprogrammed or initialised by off-board test equipment. Test sequences define the succession of interactions between the user (i.e. workshop or assembly line s
17、taff), the diagnostic application (the test equipment) and the vehicle communication interface as well as any calculations and decisions that have to be carried out. Test sequences provide a means to define interactive, guided diagnostics or similar test logic. Today, the automotive industry mainly
18、relies on paper documentation and/or proprietary authoring environmments to document and to implement such test sequences for a specific test application. An author who is setting up engineering, assembly line or service diagnostic test applications needs to implement the required test sequences man
19、ually, supported by non-uniform test sequence documentation, most likely using different authoring applications and formats for each specific test application. This redundant effort can be greatly reduced if processes and tools support the OTX concept. ISO 13209 proposes an open and standardized for
20、mat for the human- and machine-readable description of diagnostic test sequences. The format supports the requirements of transferring diagnostic test sequence logic uniformly between electronic system suppliers, vehicle manufacturers and service dealerships/repair shops. This part of ISO 13209 repr
21、esents the requirements and technical specification for the fundament of the OTX format, namely the “OTX Core“. The Core describes the basic structure underlying every OTX document. This comprises detailed data model definitions of all required control structures by which test sequence logic is desc
22、ribed, but also definitions of the outer, enveloping document structure in which test sequence logic is embedded. To achieve extensibility the core also contains well-defined extension points that allow a separate definition of additional OTX features without the need to change the core data model.
23、ISO 13209-3 extends the Core by a set of additional features, using of the Core extension mechanism (which may also be applied for proprietary extensions). This part of ISO 13209 is the most generic and stand-alone part of ISO 13209. In principle, it is also applicable in other areas for any sequent
24、ial logic description, even outside the automotive domain. Automotive-specific features are therefore contained solely in ISO 13209-3. INTERNATIONAL STANDARD ISO 13209-2:2012(E) ISO 2012 All rights reserved 1 Road vehicles Open Test sequence eXchange format (OTX) Part 2: Core data model specificatio
25、n and requirements 1 Scope This part of ISO 13209 defines the OTX Core requirements and data model specifications. The requirements are derived from the use cases described in ISO 13209-1. They are listed in the requirements section which composes the first major part of this document. The data mode
26、l specification aims at an exhaustive definition of all OTX Core features implemented to satisfy the Core requirements. Since OTX is designed for describing test sequences, which themselves represent a kind of program, the Core data model follows the basic concepts common to most programming languag
27、es. Thus, this part of ISO 13209 establishes rules for syntactical entities like parameterised procedures, constant and variable declarations, data types, basic arithmetic, logic and string operations, flow control statements like loop, branch or return, simple statements like assignment or procedur
28、e call as well as exception handling mechanisms. Each of these syntactical entities is accompanied by semantic rules which determine how OTX documents are to be interpreted. The syntax rules are provided by UML class diagrams and XML schemas, whereas the semantics are given by UML activity diagrams
29、and prose definitions. With respect to documentation use cases, special attention is paid to defining a specification/realisation concept (which allows for “hybrid“ test sequences: human readable test sequences that are at the same time machine-readable) and so called floating comments (which can re
30、fer to more than one node of the sequence). The Core data model does NOT define any statements, expressions or data types that are dependent on a specific area of application. 2 Normative references The following referenced documents are indispensable for the application of this document.
