Information system and distributed control for a control loop cell architecture

The authors present a control loop cell architecture based on distributed control using a manufacturing network. The information system handles quality management over this architecture. Quality management in the flexible cell is introduced, and the quality control loop architecture is defined. The flexibility requirements are specified. The information system structure is developed by means of entity-relationship diagrams and their metamodel. The manufacturing message specification is used to realize distributed control and to take into account the entire quality information. An application developed in the laboratory is described
