Architecture of Flexible and Reliable Control & Monitoring System for Distributed Machining Systems

Abstract: Recent control and monitoring system (CMS) can access diverse information of multi-vendor systems through open-system features of the latest CNC's, and plays decisive roles of interactive manufacturing information exchanges between the higher-level production systems and the field-level control equipments. This paper deals with a flexible and reliable architecture of CMS, aiming at the real-time networked control and monitoring in the distributed production environments. The developed CMS has a component-based network framework to flexibly access and integrate the individual information of various control equipments including CNC's, and dynamic mapping function to provide flexible communications between the field level to the business level. It has been investigated that the XML data exchange facility on the developed network framework can provide reliable and flexible connectivity between higher-level production systems and control equipments in shop-floor systems.
