This paper deals with the deployment of industrial control applications in distributed devices (considered as multi-tasking Programmable Logic Controllers (PLCs)). These applications are developed according to the component-based standard IEC 61499. In this standard, a function block is an event triggered component and the application is a network of distributed blocks on several devices. To deploy these blocks in feasible OS tasks of the execution support, we propose a hybrid scheduling approach allowing in particular to check according to specifications the temporal behavior of the application in devices and also on the communication network. This approach is based on static and dynamic policies. The static policy allows to construct OS tasks from function blocks, whereas the dynamic policy allows their scheduling at run-time.
