OTX ISO 13209 - Open Test sequence eXchange format

Controlling diagnostic sequences

OTX (Open Test sequence eXchange format) describes a sequence language for exchanging diagnostic sequences in the ECU life cycle.

The actual linguistic scope (core) is tailored to the particular diagnostic application with standardized extensions, but is also easy to extend with proprietary solutions for other applications.

Softing experience

Softing actively drove the standard from the beginning and contributed its extensive experience with test sequence languages (e.g. EDIABAS, INPA, TestCASE, DTS). We also accompanied the various evolution stages with implementations that ran concurrently to standardization. Today, our product portfolio includes an OTX Editor and a runtime interpreter. We have also already implemented customized extensions in both the editor and runtime interpreter and compiled first authoring guidelines.
