Design of Control System Based on PLC & Touch-screen for Hot Plate Machine

To improve automation degree of plastic hot plate machine,a touch control system plan is devised. The touch screen was used as HMI,and PLC as the core of temperature collection and control.According to the demands of processing and mechanical control,the control system framework was established,setting the relevant hardware configuration and software programs of realize the measurement and monitoring of hot plate machine in full automatic control.Practical application shows that ,the system is advanced,sensitive and higher precision of control with reliable configuration system,stability,simple operation,convenient maintenance,and higher ratio of cost performance.[Ch,2 fig.9 ref.]
