Abstract : This paper deals with the component based standard IEC 61499. A function block (FB) is an event triggered component and an application is a network of FBs. This network is centralized in a multi-tasking PLC. To validate the temporal behavior of the application blocks, we propose a hybrid scheduling approach combining off-line and on-line policies. The off-line policy allows to generate pre-schedulings for FBs. We associate one pre-scheduling to one task of the PLC. We apply then an existing schedulability condition to check the feasibility of these tasks.
