Abstract

Dawn Tilbury, University of Michigan 0075426 Workshop on Logic Control for Manufacturing Systems Discrete part manufacturing systems typically consist of numerous machines working together in a coordinated and sequential fashion. Programmable logic controllers are widely used to implement the control algorithms for these machines. Systems with hundreds or thousands of inputs and outputs, many of them simple on/off switches, are not uncommon. The logic controller must handle not only the normal operation sequence and synchronization of the machines, but also the operator interface and error handling and recovery routines. The purpose of this workshop is to bring together participants from industry and academia to create an understanding of the gaps which exist between the theory of discrete-event systems and control and their implementation in industrial manufacturing systems. The focus will be on coordination and sequencing problems, complexity management, error handling and recovery, automatic generation of executable code, and control verification.
