Abstract: The dependability of an automation system is a quality that depends on all the systems components. The introduction of non-deterministic networks to the automation field leads to new questions in the analysis of the resulting systems. For the analysis of systems containing non-deterministic components, probabilistic model checking (PMC) is a promising formal approach. This paper investigates the application of existing techniques and tools from PMC to the analysis of delay times in networked automation systems under the consideration of component failures. A case study shows how properties, relevant for the reliable functioning of an automation system, can be checked.
