which include supervision, maintenance, technical management, ... objectives lead to the development of Distributed Intelligent Automated Systems ŽDIAS.. The design of such systems rests on the analysis of functional, hardware and operational architectures. In this paper, we introduce a model of functional architectures which rests on distribution atoms and which provides some characteristics of the functional architecture. Then, we describe the characteristics which can be used to choose the hardware architecture. We show the problems linked with the validation of this architecture. ŽAuthor abstract . 17 Refs.

IEEE, Los Alamitos, CA, USA,94CH3319-1. p 1196-1199 CODEN: IEPREA Publication Year: 1994 Abstract: The difficulty of reaching an agreement on a single standard field-bus proposal inside the international standardization bodies has led some national organizations in Europe to develop their own field-buses and to adopt them in pilot applications. At present FIP and PROFIBUS appear to be the most widely accepted solutions and some commercial products based on these standards are beginning to be introduced on the market. Field-buses were primarily conceived for process control applications, however this paper deals with a project aimed at showing the use of the field bus technology in general, and of the FIP protocol, in particular, in the numerical control field i.e. to connect the controller, sensors and actuators inside a single machine. In such a way two benefits can be achieved immediately: a dramatic reduction in the number of cables inside a single machine and a simple low-cost interface with the manufacturing environment which is based on field-bus communication technology. In a first phase of our project the controller, sensors and actuators are simulated by software programs running on a network of personal computers called FIPNET while in a second phase the hardware and software components will be ported to a prototype environment containing real devices. The main goal of FIPNET is to verify whether the FIP field-bus is able to meet the real-time requirements of the NC applications. ŽAuthor abstract . 4 Refs.

Title: FIELDBUS AND CNC ARCHITECTURE: TOWARDS A CNC SOFTWARE FACTORY Author(s): Decotignie, J.-D. Corporate Source: Swiss Federal Inst of Technology, Lausanne, Switz Conference Title: Proceedings of the 1994 IEEE Symposium on Emerging Technologies & Factory Automation Conference Location: Tokyo, Jpn Conference Date: 19941106-19941110 Source: Novel Disciplines for the Next Century IEEE Symposium on Emerging Technologies & Factory Automation 1994. IEEE, Piscataway, NJ, USA,94TH8000. p 338-344 CODEN: 002020 Publication Year: 1994 Abstract: The purpose of this paper is to explain the needs for introducing fieldbuses in machine-tools, a design choice whose economic benefits may not be apparent. We first explain the general trends of the factory of the future and its impact on the machine-tools characteristics and hence on computer numerical controllers ŽCNC.. We then show how the requirements can be fulfilled and the resulting architecture that opens the road to CNC software factory. One distinctive aspect of this architecture is the concept services, or vertical reusable components. Distributed interpolation that we briefly describe play an important role in designing good components. In a second part, we describe the different architectural levels inside the CNC and we explain the reasons why a fieldbus should be introduced to link field devices to the CNC and at which level. Finally, we present an example of fieldbus use in a milling machine and the resulting performances. ŽAuthor abstract . 21 Refs.

IEEE, Piscataway, NJ, USA,94TH8000. p 304-307 CODEN: 002020 Publication Year: 1994 Abstract: MMS ŽManufacturing Message Specification. was initially designed for interconnection of industrial devices in manufacturing and process control applications. Typical devices supporting MMS are numerical controllers of machines, programmable controllers, etc. Given the wide applicability of MMS services, MMS can be applied to new areas such as building automation, field buses and remote reading. Such applications have much stronger constraints concerning the
