Abstract :
Lower level machines of production line are mainly controlled by PLC and CNC. Reconfiguration control mechanism and implementation of these two kinds controller have its own way due to different characteristics of individual control domain. Combining them totally in one production line manufacturing environment to form reconfigurable control architecture in system level is focused on. First reconfigurable control for single PLC and CNC controller is studied. Transformation rules from IEC 61131 standard to IEC 61499 reference structure and STEP-NC compliant reconfigurable numerical controller are respectively studied to implement reconfigurable control for single PLC and CNC based machines. And on this basis an extensive IEC 61499 compliant software architecture for reconfigurable control of lower level machines in networked manufacturing of production line is proposed by considering systematic reconfiguration requirement and philosophy in production line environment.
