Temporal validation of an IEC 61499 control application
Abstract
This paper deals with the temporal correctness of control applications designed using the componentbased standard IEC 61499. In this standard, a function block is defined as an event trigger component containing its own data. To validate temporal behavior of an application, we have to take into account its scheduling on the execution support. We propose an abstraction of component behavior taking into account all its possible executions. We propose to verify the temporal correctness of the application with regard to global temporal properties (end to end delays). Thanks to such characterization, we show that it is possible to check deadlines for the application to ensure its correctness. To reach this goal, we transform the application into a dependant tasks model.
