Abstract:
In this paper it is presented the analysis of real-time industrial controllers when it is taken into account human behavior in the use of fully automated industrial systems. It is intended to develop safe controllers for these systems and make them robust against inappropriate utilizations by human operators. For the attainment of our goals it is used a case study, where, based on a IEC 60848 specification, is deduced the controller program. Further, it is elaborated the controller model, the Plant model and the Human Machine Interface Model of the automated system. The obtained results are generalized for other similar systems with the presented case study.
