Softing OTX.runtime – High-performing Runtime Environment

An independent runtime environment for running OTX sequences in compliance with ISO 13209.

Softing OTX.runtime is an ISO 13209 compliant and high-performing runtime environment which also runs complex OTX scripts. It can be integrated in proprietary applications for the automation of test and diagnostic sequences regardless of the operating system.

Areas of Application

  • Test sequences in ECU development
  • Flash sequences in manufacturing
  • EOL tests
  • Setting and verifying diagnostic parameters for open loop test systems
  • Guided sequences for efficient use in the repair shop
  • Diagnostics on embedded devices


  • Process security thanks to standardized format
  • Can be used flexibly over the entire process chain
  • Easy-to-learn API for efficient integration in existing applications
  • Simple handling and exchangeability of OTX sequences
  • Saving of time thanks to reusability of the OTX scripts
  • Suitable for all operating systems regardless of the platform
  • Accessible as a stand alone even with a proprietary application
  • Know-how protection thanks to specific encryption and certificates


OTX - additional intelligence for diagnostics and test tasks

Softing's OTX Runtime runs OTX scripts efficiently and safely. The range encompasses everything from simple test sequences to complex sequences for diagnostic testers and test systems. Tasks from Diagnostics and Testing can be used reliably both within a company and in collaboration with suppliers. The OTX Runtime from Softing is completely ISO 13209 compliant. It thus enables the use of OTX sequences from any authoring system as well as the execution of all extensions in OTX Studio which the standard does not include.

Simple access via OTX RT API and the command line

Softing's OTX Runtime is accessed via an extensive programming interface (API) and enables the direct execution of all OTX extensions - just like all Softing applications. The OTX Runtime API is easy to learn and enables user-friendly access and efficient integration into proprietary applications. Calling functions via the command line also offers even more flexibility when using OTX Runtime in proprietary applications.

Safeguarding expertise - encrypting data

The OTX sequences contain considerable know-how which in many cases should not be able to be read or changed by unauthorized persons. This is why Softing has incorporated encryption. Certificates created specially for every OTX script make it possible for the OTX Runtime to check the integrity of the scripts. OTX Runtime does not allow execution if a check shows any problems with the integrity of the scripts. Furthermore, OTX scripts can be converted into a customized encrypted binary format.

Can be used with all conventional operating systems

Softing's OTX Runtime can be used with various applications independent of the platform. End devices thus include Android or iOS smartphones or tablets. But the sequences can also be used on a PC with Windows or Linux as well as in embedded devices without any changes having to be made.
