APPLICATION OF PLC & WinCC IN VACUUM PRESSURE MACHINE ARRAY

The paper introduced mechanism and operating principle of the Vacuum Pressure Machine Array and analyzed overall control system and difficulty of temperature controlling,adopted algorithm of auto-turning of PID parameters and Siemens temperature control module——FB58,the paper solved the problem of temperature controlling of hot board.Author configured the control system of hot oil and control panel of temperature of hot machine A utilized the software of WinCC V6.0.The PID parameters of system would be turned automatically by simple operation.The practical application indicated that the effect of overall control system was accurate and credible.
