The paper presents a modular control model to develop the control functions for manufacturing systems and its implementation using IEC 61499 function blocks. In particular, a new control module for automation objects is formally specified and its use on a hierarchical functional architecture has been discussed and the possible distribution of its IEC 61499(More)
The paper presents the design and implementation of an innovative Integrated Development Environment, developed within the on-going European Research Project TORERO, to model and design reusable distributed control systems (DCS). This project proposes an architecture which relies on a development environment based on the Eclipse tool and the emerging(More)
In this paper, we present a distributed automation solution, mainly conceived for manufacturing applications, that is based on a new basic building block for a control device. Such a basic automation component incorporates many features drawn from ICT technologies, namely, service-oriented functionalities, Plug-and-Participate capabilities, Java Virtual(More)
This paper discusses the design and the development of a control architecture for reconfigurable manufacturing systems. It presents the approach proposed by the PABADIS' PROMISE European research project which targets the issues of reconfigurability, flexibility, and efficiency in the context of the interaction among the three levels of the control pyramid(More)
The paper deals with the implementation of IEC 61499 applications into executable code. In particular, this work concerns the automatic conversion of a IEC 61499 application into an AWL application executable on a standard Siemens PLC. The IEC 61499 Standard defines an application as a network made of Function Blocks and event/data connections. The(More)
Most applications in industrial automation could be hazardous for people, plant and environment. Therefore it is necessary for related distributed control systems, implementing safety functions for such applications, to rely on a real-time and fault tolerant communication among all connected stations. To realise this objective, safety related networks(More)
The paper deals with the problem of fault detection and isolation in machining centers, which are the basis of FMSpsila. The problem is of paramount importance since an effective diagnostic system can lead to a significant increase in the autonomy of an automated system. The paper considers a special case study: an hydraulic circuit which blocks and(More)
The paper deals with the problem of modeling and implementation of distributed automation systems for manufacturing applications. In particular, a novel approach has been conceived. A suitable meta-model of the production system has been derived, compliant with the state-of-the-art industrial standards. After the compilation and validation stages, an(More)
