Abstract (EN)Since it is an important issue for users and system designers, verification of PLC programs has already been studied in various contexts, mostly for untimed programs. More recently, timed features were introduced and modeled with timed automata. In this case study, we consider a part of the so-called MSS (mecatronic standard system) platform from Bosh group, a framework where time aspects are combined with multitask programming. Our model for station 2 of the MSS platform is a network of timed automata, including automata for the operative part and for the control program, written in Ladder Diagram. This model is constrained with atomicity hypotheses concerning program execution and model checking of a reaction time property is performed with the tool UPPAAL.
