The German guideline VDI 2180-5 addresses functional safety with the intention of minimizing complexity while not compromising safety and risk reduction achieved by means of safety instrumented functions.
On the basis of straight forward standardized approaches such as limited choice of architecture and proof test strategies, a consistent “alternative guideline” for safety lifecycle activities is described.
The presentation shortly introduces the referred “Basic concept for implementing functional safety in the process industry” in order to foster an interactive discussion aiming to determining the limits of simplicity and beyond these limits the need for more sophisticated approaches and tools.
