Towards Reconfiguration Applications as basis for Control System Evolution in Zero-downtime Automation Systems

Publisher Summary Industrial Automation and Control Systems will evolve toward downtimeless, adaptable, and distributed real-time systems. The reconfiguration of control applications is not sufficiently solved by state-of-the-art technology. This chapter presents an overview of the use of reconfiguration applications for downtimeless system evolution of control applications on basis of the standard IEC 61499. This new methodology combines the need for close interaction with the application/physical process and the existing knowledge about the modeling of control applications. By use of a representative example the structure, the required instruction set and the methodology for the downtimeless system evolution utilizing a reconfiguration application are described. The special requirements, which concern the topics verification, failure handling, and the runtime platform, are also presented.
