This paper describes plant modeling using DES (discrete event system) in generic model, and designing the controller for PLC-based manufacturing system. The tested model through simulation can be automatically transformed into LD (Ladder Diagram) program analyzing the controller elements. In addition, through the simulation of devices and controllers, possible logical errors can be minimized. The contribution of this work is to generate small and medium sized PLC-programs and reduce down-time and ramp-up time.
