In this research an integrated IDEF/CTPN/SFC approach is proposed to develop a discrete event control system. The proposed approach includes three stages. First, IDEF is used for the functional and activity flow description of system due to its structural and hierarchical features. Secondarily, IDEF/ is converted into CTPN for dynamic behavior analysis. Finally, CTPN is converted into SFC for PLC language design. The Petri net model converted from IDEF is more systematic and structural than that directly obtained from system description. The proposed these stage methodologies and the conversions between IDEF/CTPN and CTPN/SFC provide a complete method and tool for designing discrete event control system. In addition, it can reduce errors and save the time for developing the control system.
