ASAM OTX Extensions

ASAM Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX in conjunction with International Organization for StandardizationISO 13209 (Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX) can be used in any application area where the definition of test procedures for documentation purposes or in an automation system is required. Typical application areas in the automotive industry are in ECU The subsystem of an ECU or ECU networks, which performs error detection, handling and communication.diagnostics testing, ECU The process of ECU parameter tuning. Tests with ECU hardware and software in the loop are carried out. ECU internal variables and external sensor data is recorded and analyzed. The values of internal ECU parameters are determined as a result of this process.calibration and EOL-testing.

In 2012, International Organization for StandardizationISO published the new A public specification, which has been developed by experts in a defined consensus-driven development process and was released by officials that represent a significant share of the industry for which it is targeted, giving the specification the necessary legitimacy to be called a 'Standard'.standard International Organization for StandardizationISO 13209 "Open Test Sequence Exchange" (Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX), part 1 to 3, which has the main purpose to define a language and exchange format for the A document, which describes in detail the interfaces and behavior of a technical system for the purpose of implementing, integrating and operating the system.specification of executable test sequences. Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX has originally been developed for the area of ECU The subsystem of an ECU or ECU networks, which performs error detection, handling and communication.diagnostics testing, but is not limited to this area. Soon after the first Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX-based systems appeared on the market, end users required additional functionality, which were promptly implemented by tool suppliers. Some of the requested functionality, such as file processing or specific complex data types, impeded the exchangeability of Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX files and the interoperability of test systems. Consequently, there was a need to further standardize the additional functionality.

ASAM Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX fills those functional gaps of International Organization for StandardizationISO 13209. Overall, 23 extensions are defined in ASAM Open Test Sequence Exchange Format (ISO & ASAM Standards)OTX, which include:

• Ensuring otx sequence quality 
• transport customer specific data types 
• Collection of communication data at runtime 
• Handling of communication interfaces and Diagnostic over IP 
• Dialogs for common use cases 
• Definition of of user defined structure and enumeration data types 
• Support of different ECU responses for hex service and com channel controlling 
• Configuration of project and vehicle information 
• Browsing of ODX database properties 
• ECU variant coding 
• Support for deep change monitoring in a List or Map 
• Provides actions, terms, events and data types for an access to external services. 
• General read and write access to files
• Enable late binding of flash files 
• Store runtime information of an equal run-time system 
• Read and write access to a SQL data base 
• Description of a behavior model with states, transactions and actions 
• Mechanism to transport status information from inside a sequence to the environment 
• Evaluated and structured storage of result Information (e.g. for statistics) from test sequences 
• Advanced convenience functionality 
• Access to information about the vehicle network architecture 
• Read and interpret XML documents, modification of existing and creation of new documents 
• Compressed data exchange 

The A public specification, which has been developed by experts in a defined consensus-driven development process and was released by officials that represent a significant share of the industry for which it is targeted, giving the specification the necessary legitimacy to be called a 'Standard'.standard is currently being transferred to International Organization for StandardizationISO 13209 as part 4.
