This paper deals with the simultaneous allocation and deployment of an industrial control application in a distributed execution support. We consider this support as a network of multi-tasking PLCs. The application is the composition of particular event triggered components called Function Blocks. These blocks have to respect end to end response time bounds. Once the application is correctly designed, we propose a heuristic-based approach allowing the allocation of the corresponding blocks in the execution support. This approach allows also to deploy these blocks in feasible OS tasks. To construct these tasks, we have to take into account the limitation of their number in each controller. In addition, we have to consider the functional constraints defined in the specifications.
