Road vehicles - Open interface for embedded automotive applications - Part 2: OSEK/VDX specifications for binding OS, COM and NM
ISO 17356-2:2005 gives the OSEK/VDX specifications for binding the OS (operating system), COM (communications) and NM (network management) of the open interface for embedded automotive applications. It specifies the variables (error codes, status types, etc.) programmable by the user to ensure that implementation of OS, COM and NM are coherent between each other.

Overview
ISO 17356-2:2005 is an international standard that specifies the OSEK/VDX bindings for the operating system (OS), communication (COM), and network management (NM) layers of embedded automotive applications. It is part of the ISO 17356 series, aimed at defining an open interface for embedded automotive systems. This standard ensures coherence and interoperability between OS, COM, and NM implementations by establishing consistent error codes, status types, and message handling rules.
By providing unified specifications for these core components, ISO 17356-2 supports the integration of software modules from different suppliers, enhancing reliability and reducing development complexities in automotive embedded systems.
Key Topics
OSEK/VDX Bindings
ISO 17356-2 delineates the binding specifications that link the OS, COM, and NM layers. This bonding ensures that these components work seamlessly together within embedded automotive applications.Error Codes and Status Types
A critical element of this standard is the adoption of standardized error codes (StatusType) with explicit value ranges assigned to OS, COM, and NM to avoid conflicts:- 0 represents successful completion (
E_OK). - 1-31 reserved for OS error codes.
- 32-63 for COM error codes.
- 64-95 for NM error codes.
These ranges make it possible to programmatically distinguish error sources, which is essential for debugging and system stability.
- 0 represents successful completion (
Consistency of
StatusTypeDefinition
The standard mandates that theStatusTypeshould be defined asunsigned charconsistently across the OS, COM, and NM modules. This avoids compilation conflicts and ensures interoperability when combining implementations from varied suppliers.Internal Communication Handling
ISO 17356-2 clarifies which kernel (OS or COM) manages internal communication messages depending on the communication conformance class (CCC) being used. This definition prevents message handling conflicts and ensures data type consistency in internal and external communications.
Applications
ISO 17356-2:2005 is primarily intended for developers, manufacturers, and suppliers of embedded automotive software who implement or integrate operating systems, communication stacks, and network management modules within vehicles. Practical applications include:
Automotive Embedded Systems Development
Ensures that OS, COM, and NM modules adhere to a common binding, facilitating modular design and simplifying software integration.Supplier Interoperability
Enables vehicle manufacturers to combine components from different suppliers with a guarantee of compatibility due to standardized error codes and data types.Networked Vehicle Communication
Supports consistent internal and external communication protocols within automotive networks, increasing system reliability and maintainability.Software Toolchains
Tool developers generating system configurations from OIL (OSEK Implementation Language) files rely on this standard for generating compliant and consistent communication and OS bindings.
Related Standards
ISO 17356-2 is part of a broader series addressing open interfaces for automotive embedded systems:
- ISO 17356-1 – General structure, terms, definitions, and abbreviations for embedded automotive applications.
- ISO 17356-3 – OSEK/VDX operating system (OS) specifications.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(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, governmental 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/IEC 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 member 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 17356-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3,
