By analyzing the physical construction, main composing and production process of interior parts’ molding production line in this paper. And requirements are also presented. The device hardware of the production line PLC control system is carried out by using STEP7 software. In addition to control and response system working state and running state, the design also uses the software of TIA portal for the control system produced a man-machine interface. The using of the TP1200 type touch screen while the application of the control system can also be visually monitored during operation and improve the control of the state can be monitored. The Rotating foam production line control system adopts a classification structure. The first class for the programmable logic controller PLC , this system adopts SIEMENS S7-200. It connects w
