The need for agility in manufacturing systems is continuously growing. This is caused by increasing complexity and decreasing life cycles of the produced goods. This paper proposes a modular, reconfigurable manufacturing system, based on a distributed three layer architecture, consisting of mechatronic components, an IEC 61499 based distributed low level control and on top a multi agent system as...
Downtimeless evolution of distributed automation systems (changes during runtime) sets high demands on the underlying concepts and methodologies. Within the εCEDAC project a sophisticated description of the underlying system, including state information as well as capabilities of the hardware, is used. In combination with an engineering tool it offers a great amount of engineering support, thus keeping...
IEC 61499 is introduced as a new standard for industrial process measurement and control system. Communication function blocks are however, only loosely defined as they are implementation dependant. This paper presents the definition of communication function blocks for the CIP protocol which is a well established standard in industry and describes a pilot implementation demonstrating that the standard...
Recent studies report a growing demand for downtimeless evolution of distributed automation systems. This paper therefore first analyzes evolution approaches from the industry as well as from academic research pointing out benefits and drawbacks. The standard IEC 61499 is identified as promising basis for dynamic reconfiguration of control applications, but it lacks for an adequate engineering methodology...
In today's globalized markets the manufacturing industry in traditional high-wage countries highly depends on flexible and automated manufacturing systems to remain competitive. State-of-the-art industrial control and automation systems do not sufficiently solve the problem of downtimeless reconfiguration of control applications. This paper presents an approach for structured modeling of controlled...
Future manufacturing is envisioned to be highly flexible and adaptable. New technologies for efficient engineering of reconfigurable systems and their adaptations are preconditions for this vision. Without such solutions, engineering adaptations of Industrial Process Measurement and Control Systems (IPMCS) will exceed the costs of engineered systems by far and the reuse of equipment will become inefficient...
In today's production and assembly processes, conventional PLC-based architectures are state-of-the-art for control engineering and application design. These kinds of architectures cause high costs for engineering and maintenance, especially adaptation of applications and hardware modifications create intolerable overhead. Distributed automation systems built of mechatronic components help coping...
