According to the monitoring system, this paper designed and developed the Lord Monitor screen which is used in man-machine interaction between each subsystem and monitor screen. The equipment configuration guide of the KingView defines external equipments, so that realizes the communication of upper and lower machine (PLC, frequency converter).On basis of that, the Data Change Command Language realizes user-defined protocol between the computer and PLC , writes control programs and realizes the simulation test of the cascade pressure monitoring system. In addition, the monitoring system has the parameter setting function, the reporting function, the curve of data report showing function and the querying function. Through the simulation testing, this paper designs the automatic control process procedures of the monitoring system, the reporting procedures of the monitoring system, the historical trend curves procedures of the monitoring system and the real-time trends curves procedures of the monitoring system, and verifies the reliability of the monitoring system. Finally, the applications of the configuration software in the design and development of the
