The Study on Liquid Level Control System Based on PLC and WinCC

Abstract:

Based on the PLC control technique and WinCC configuration technology,the control system for the liquid level of the tank was designed. After receiving liquid level signal that transferred from radar tester,the PLC process it ,and then output related control signal to the actuator.The actuator is composed of two AC motors,one is for the main pump ,and another for the auxiliary pump.The function of human-machine interface is achieved with the help of Smart700 touch screen of Siemens.Communication functions between the WinCC project and the PLC site and pictures of the control process which enabals real-time monitoring of the entire system are finished by designing configuration.Finally,the validity of the system and the feasibility of the design have been proved by debugging and the use of enterprises.
