Information architecture for reconfigurable production systems
The trend towards greater flexibility in production system has impact on industrial communication. One of the challenges for future research and development is to simplify the connectivity between automation equipment (e.g. robot and machine tool). Still automation equipment is connected via digital inputs and outputs or fieldbus systems and configuration can only be done at considerable expense. To meet the requirements for higher flexibility in robotized manufacturing cells an information and communication architecture, in which new components (e.g. NC controls) can easily be integrated, is required. In this paper we present a cell cache based on blackboard communication architecture that allows adding or removing hard and software-components without reinventing the information architecture. For implementation of the developed approach a robotized manufacturing cell consisting of two machine tools and a robot was assembled.
Key words: robotized manufacturing cell, blackboard, XML, robot, machine tool
