A Formal Approach to Deploy Heterogeneous Software Components in a PLC

This paper deals with an industrial control application following different component-based technologies. This application, considered as a network of heterogeneous components, has to be deployed in a multi-tasking PLC. It has classically to respect temporal constraints according to specifications. To deploy the components in feasible OS tasks of the controller, we propose to fix a formal component model allowing their homogeneous design. We enrich, in particular, this model to unify well known technologies. The application is considered then as a network of homogeneous components. We propose to transform this network into a real-time tasks system with precedence constraints to exploit previous results on real-time deployment.
