Abstract
This paper presents a controlling system which controls the special traveling crane for electroplating. With a PIE. This system really helps improve the reliability and laity of the controlling system. And this paper introduces the application of Rockwell PLC in the plating product line.The system can achieve auto-control and manual-control, and be switched flexibly between the two methods. Modularization is the fundamental aspect of the programming designs. Advantages of this method includes convenience for debugging, simplicity for maintenance and good transplantation.
