This article focuses on the S7300 PLC liquid level monitoring system, including its hardware components, work-ing principle, PLC programming, the establishment of the database in MCGS configuration, the connection to the PLC, monitor-ing interface and so on. The system put into operation after debugging and adjusting the PID parameters. The system solves the problems that the PLC control system can not display. It can start adjustment timely, rapidly with no error and can easy to moni-tor. It makes enterprise management more convenient and efficient improve the level of automatic control.
