13、(ISO member bodies). The work of preparing International Standards is normally carried 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, g
14、overnmental and non-governmental, in liaison with ISO, also take part in the work. ISO 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/I
15、EC Directives, Part 2. The main task of technical committees is to prepare International 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 mem
16、ber bodies casting a vote. Attention is drawn to the possibility that some of the elements 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 17356-6 was prepared by Technical Committee ISO/TC 22, Road vehicles,
17、Subcommittee SC 3, Electrical and electronic equipment. ISO 17356 consists of the following parts, under the general title Road vehicles Open interface for embedded electronic equipment: Part 1: General structure and terms, definitions and abbreviated terms; Part 2: OSEK/VDX specifications for bindi
18、ng OS,COM and NM; Part 3: OSEK/VDX Operating System (OS); Part 4: OSEK/VDX Communication (COM); Part 5: OSEK/VDX Network Management (NM); Part 6: OSEK/VDX Implementation Language (OIL).

19、opy, (c) BSI v 0 Introduction 0.1 General remarks This part of ISO 17356 refers to ISO 17356-2, ISO 17356-3 and ISO 17356-4. For a better understanding of this document, the reader should be familiar with the contents of these other specifications. 0.2 Motivation To reach the goal of portable softwa
20、re, this part of ISO 17356 defines a way to describe the configuration of an application. This part of ISO 17356 only addresses a single central processing unit (CPU) in an electronic control unit (ECU), not an ECU network. Figure 1 Example of development process for applications Figure 1 shows an e
21、xample of a development process for applications. The ISO 17356-6 description may be handwritten or generated by a system configuration tool. There can be several ISO 17356-6 files, e.g.: files which contain CPU-specific configuration items (created by the supplier); and files which contain configur
22、ation items for the entire network (provided by the OEM). Sub-systems delivered in source code are compiled together with the application; others delivered as a library are integrated by the linker.

24、mentation Language (OIL) concept for the description for ISO 17356 real-time systems, capable of multitasking and communications, which can be used for motor vehicles. It is not a product description that relates to a specific implementation. General conventions, explanations of terms and abbreviati
25、ons are compiled in a glossary, which is part of ISO 17356-1. 2 Normative references The following referenced documents are indispensable for the application of this document.

This means for each CPU there is one ISO 1
29、7356-6 description. All system objects are described using ISO 17356-6 objects. BS ISO 17356-6:2006 Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26 14:25:55 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 2 3.2 General concept The ISO 17356-6 description of the application is considered to be comp
30、osed of a set of ISO 17356-6 objects. A CPU is a container for these objects. This part of ISO 17356 defines standard types for its objects. Each object is described by a set of attributes and references. This part of ISO 17356 defines explicitly all standard attributes for each ISO 17356-6 object.
31、Each implementation can define additional implementation-specific attributes and references. It is possible only to add attributes to existing ISO 17356-6 objects. Creating new ISO 17356-6 objects, or other changes to the grammar, are not allowed. All non-standard attributes (optional attributes) ar
32、e considered to be fully implementation-specific and have no standard interpretation. Each implementation can limit the given set of values for attributes (e.g. restrict the possible value range for priorities). 3.2.1 ISO 17356-6 file structure The ISO 17356-6 description contains two parts one part
33、 for the definition of standard and implementation-specific features (implementation definition), and another for the definition of the structure of the application located on the particular CPU (application definition). The ISO 17356-6 description consists of one main ISO 17356-6 file that can refe
34、r to included files (see 3.2.9). 3.2.2 Syntax The grammar rules for an ISO 17356-6 file are presented in the document using a notation similar to the Backus-Naur Form (BNF) 1, 2, see 6.1. All keywords, attributes, object names, and other identifiers are case-sensitive. Comments in the BNF notation a
35、re written as C+-style comments. 3.2.3 ISO 17356-6 versions Two ISO 17356-6 sets of objects and standard attributes are defined: Full set of objects and standard attributes: ISO 17356-3 and full-featured ISO 17356-4, supporting the conformance classes BCC1, BCC2, ECC1, ECC2, CCCA, CCCB, CCC0, CCC1.
36、Subset of objects and standard attributes: ISO 17356-3 with internal communication only, supporting the conformance classes BCC1, BCC2, ECC1, ECC2, CCCA, CCCB. Refer to ISO 17356-3 and ISO 17356-4 for the features available with each of the abovementioned conformance classes. 3.2.4 Implementation de
37、finition For each ISO 17356-6 object, the implementation definition defines all attributes and their properties for a particular implementation. The implementation definition shall be present in the ISO 17356-6 description and have to contain all standard attributes, which are listed in 4.2. The val
38、ue range of those attributes may be restricted. Attribute definition is described in clause 5. Additional attributes and their properties can be defined for the objects for a particular implementation. Additional attributes are optional.

39、, Sun Nov 26 14:25:55 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 3 The include mechanism (see 3.2.1) can be used to define the implementation definition as a separate file. Thus, corresponding implementation definition files can be developed and delivered with particular implementations and then inc
40、luded with the application definition in users ISO 17356-6 files. An implementation of ISO 17356-6 shall support either all objects and standard attributes or a specific subset defined in 6.2.1. 3.2.5 Application definition The application definition comprises a set of objects and the values for the
41、ir attributes. Except for the ISO 17356-3, ISO 17356-4 and ISO 17356-5 objects, the application definition can contain more than one ISO 17356-6 object of a particular type. Each object is characterized by a set of attributes and their values. No attribute may appear that is not defined in the imple
42、mentation definition. Attribute values shall comply with the attribute properties specified in the implementation definition. Attributes that take a single value shall only be specified once per object. Attributes that take a list of values shall be specified as multiple statements. Example for a mu
43、ltiple statement: RESOURCE = RES1; RESOURCE = RES2; 3.2.6 Dependencies between attributes This part of ISO 17356 allows the expression of dependencies between attributes. To be more open to vendor-specific and standard extensions, the ISO 17356-6 syntax includes conditional attributes (parameters).
44、This part of ISO 17356 allows infinite nesting of those dependencies. To express dependencies, ENUM and BOOLEAN attributes can be parameterized. If attributes in several sets of one conditional attribute have the same name, they shall have the same type. 3.2.7 Automatic attribute assignment Attribut
45、e values may be calculated by the generator. For these attributes, the keyword WITH_AUTO shall be used in the attributes definition in the implementation definition. In conjunction with WITH_AUTO, the attribute value AUTO is valid in the application definition and as a default value. 3.2.8 Default v
46、alues Default values are used by the generator in the case that an attribute is missing in the application definition. Default values are mandatory for optional attributes. Because the syntax of the implementation-specific part requires the definition of default values, a special default value NO_DE
47、FAULT is defined explicitly to suppress the default mechanism. In this case, the attribute shall be defined in the application part. Default values are forbidden for standard attributes except if explicitly stated otherwise in the specification. If a default value is allowed for a standard attribute
48、, it is defined in 6.2. It is an error if a standard attribute that does not have a default value defined in the implementation definition is missing from the application definition. ISO 17356-6 grammar uses assignment in the implementation definition to specify default values. All possible combinat
49、ions of attributes with default values are shown in Table 1. The ISO 17356-6 syntax allows six combinations for the implementation-specific part and three combinations for the application part.
