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 PLC-based 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)
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. Those(More)
This paper presents a methodology for the characterization of an IEC 61499 runtime environment by use of a benchmarking procedure. Due to the usage of IEC 61499 for low-level control as well as the paradigm of application centered engineering<sup>1</sup>, it is necessary to describe the capability to execute IEC 61499 function block networks. There are two(More)
The automation of plants and machines is becoming more and more complex due to the extensive usage of intelligent field devices as for instance programmable actuators and sensors. The graphical programming languages used are typically for the automation domain, and control applications tend to be become increasingly complex which results in higher(More)
