Research on the Realization of Variable Frequency Speed Regulation Monitoring Network of Asynchronous Motor Based on the Communication between S7-1200 and G120 of USS Fieldbus

文章提出通过USS现场总线将西门子S7-1200和G120变频器连接起来,组成多台异步电动机变频调速监控网络,并在HMI上实现人机交互。该控制系统成本相对较低、电缆数量减少、多台电动机可同时分别控制、电机运行状态实时显示,控制系统稳定性、可靠性、灵活性大大提高。

In this paper,Siemens S7-1200 and G120 frequency converter are connected by USS fieldbus to form a monitoring network for variable frequency speed regulation of multiple asynchronous motors,and the humancomputer interaction is realized on HMI.The cost of the control system is relatively low,the number of cables is reduced,multiple motors can be controlled separately at the same time,and the running status of the motor is dis⁃played in real time.The stability,reliability and flexibility of the control system are greatly improved.
