NCES-based modelling and CTL-based verification of reconfigurable Benchmark Production Systems

Abstract

This paper deals with the development of Safety Reconfigurable Embedded Systems following the International Industrial Component-based Standard IEC61499. To handle all possible reconfiguration forms, we propose at first time an Agent-based Architecture where the Agent applies automatic reconfigurations to adapt the system according to well defined conditions. We model this agent with nested state machines according to the formalism Net Condition Event Systems which is an extension of the Petri net formalism. In order to satisfy user requirements, we specify functional and temporal properties with the temporal logic CTL (as well as its extensions ECTL and TCTL) and we apply the Model Checker SESA to check the whole system correctness.
