In this paper, a Petri net-based logic and sequence control model of photo mask transport was constructed. A characteristic analysis was made on the established Petri net model in behavior and structure. This checked the safeness and reliability of the constructed control model off line. In order to implement the Petri net-based control model of photo mask transport via a Programmable Logic controller (PLC), an approach was proposed to generate Ladder Logic Diagram (LLD) programs from the Petri net-based control model. Execution of the generated LLD programs validated the effectiveness of the proposed method.
