The ever increasing complexity of manufacturing systems demands for new real-time control infrastructures. With the new standard IEC 61499 the IEC introduced a base for such a control infrastructure. An open issue of this standard is the missing definition of real-time execution. Based on existing real-time execution theory different execution models for(More)
In modern production and assembly processes, conventional PLCbased architectures are state-of-the-art for control engineering and applications. These kinds of architectures cause high costs for engineering and maintenance, and specially the adaptation of applications or even hardware changes are problematic. The paper presents a new modular control(More)
This paper provides an overview of current techniques to allow the industrial systems to automatically adapt to change while maintaining predictable and stable system behaviour. This is performed along the dimensions of simple, dynamic and intelligent reconfiguration and focuses on the physical device and software component levels of the shop floor and in(More)
This paper presents ongoing work focused on dynamic reconfiguration of industrial automation systems as a part of their total life cycle. Modification of the control logic has to be enabled at runtime and without any disturbances of related applications. The epsivCEDAC engineering cycle for dynamic system evolution is based on the use of an IEC 61499(More)
The new IEC 61499 standard provides new concepts and paradigms of system engineering to the automation and control system domain. But the customer can not start from scratch and develop their systems new as they have invested a lot of money into libraries and control logic. Therefore this paper aims at a transformation of existing IEC 61131-3 automation(More)
This paper provides a possibility for a semantic correct transformation of existing IEC 61131-3 projects into the newer IEC 61499 standard. Based on a model driven development approach as well as proper concepts and rules this paper describes a suitable way to overcome some semantical problems which occurred during the transformation process.
