摘　　要：介绍了在离心机控制系统中的一项技术,它利用变频器的RS485串行通讯接口和PLC进行Modbus协议通讯,从而实现了PLC与变频器的串行通信控制,达到监控离心机系统设备多组参数的同时还能降低系统成本的目的。This paper introduced a communication technology in centrifuge control system. It used RS485 serial communication interface of frequency converter to communicate with PLC by Modbus protocol. Thus the serial communication control between PLC and frequency inverter was realized. The communication technology could be sure to monitor the multi parameters of centrifuge system and reduce the costs of the control system.
