Abstract

This study presents a system for validating the PLC code in the virtual environments of automobile trim line. There have been considerable efforts to develop standard PLC editors for saving human power and PLC test time. However, it was difficult to apply the PLC editor on a real shop floor environment. A virtual equipment was developed to communicate with the PLC module of a shop floor and to make up the connectivity environment by a special protocol. We can validate the code without launching real equipments because the PLC module and the virtual equipment is able to be controlled in real time by the OPC protocol. An experimental model is applied to the final assembly line of an automotive industry and validated by using DELMIA Automation. In conclusion, the system is valuable in the process of PLC codes validation and virtual equipments operation. This system would reduce the development time of the PLC codes and improve the productivity and the integrity of the PLC codes.
