GRAFCET Based Modelling of Processing Operation in Modular Production System

This paper implements GRAFCET based model for processing station in modular production system. The GRAFCET for the sequence of operation in processing station was implemented and equations were extracted from the GRAFCET followed by converting the equation into equivalent ladder logic program. The implementation of the ladder logic program was performed using Codesys 2.3V software and hardware used to check the reliability of the program was modular production system - Processing station. The proposed GRAFCET based model was found to be reliable, efficient and accurate in performing the control sequence in the processing station. In future the GRAFCET will be implemented in the form of sequential flow chart instead of converting it into ladder logic programming which is time consuming.
