EN 50128 configurable Systems: Chapter 8 of EN 50128 specifies the requirements for systems that are configured by application data or application algorithms (EN 50128 configurable Systems). This blog summarizes the essential requirements of the standard and the practice-oriented challenges of software-configurable embedded systems.
At the first glance the configurability offers only advantages. The functional behavior of the entire system can be adjusted by simple and rapid changes in the application data to the desired behavior. The source code of the generic software is not to changed. A multiple reuse is possible thereby. If it is well done, even the unit tests should be reuseable, without any change. The EN 50128 also states that proven, generic software can be reused repeatedly in this way. These are important advantages. Read more

The EN 50128 Functional Safety standard describes together with the EN 50126 and EN 50129 the functional safety in the railway industry. These standards implement the IEC61508 for this industry.
The peculiarity of the rail industry with regard to functional safety is that the systems are to be certified by an governmental authority (in Germany the federal railway authority), before they are allowed to be placed into a railway system. So, the manufacturer must provide proof of compliance with the functional safety standards already during the development of the product. In this point the aviation and rail industry are very similar.
