The Application of Profibus in Man-Machine Cooperation FMS

This paper briefly introduces the application of Profibus-DP technology in flexible manufacturing system for settling communication problem between the control centres in the workshop layer and manufacture field.The Profibus-DP master is established in the control centre,while the Profibus-DP slave with the Profibus bridge is established in manufacture field.The Profibus bridge has Profibus and RS-232C interface.At the same time,the aid controller can communicate with the Profibus-DP slave and carry out the RS-232C communication.So the operators can send the messages such as the equipment status,the production schedule and the NC program etc to the control centre in workshop layer by Profibus-DP in aid controller.Meanwhile the control centre can send messages such as the scheduling order,the production tasks and the NC program etc to the manufacture field.Finally the communication bridge is set up between the control centre in the workshop layer and the manufacture field.
