摘　　要：以工业生产中常用的PROFINET网络技术为基础,设计了西门子S7-1200PLC与西门子S120变频器组成的控制系统,通过PROFINET总线实现了对变频器的控制。控制系统中PLC为主控单元、变频器控制交流电机转速、人机界面(HMI)进行控制指令的发送及运行状态的监控。该控制系统在某搅拌装置中得到了成功应用,试验结果表明该系统运行稳定可靠。Based on the PROFINET network technology commonly used in industrial production,the control system composed of Siemens S7-1200 PLC and Siemens S120 inverter is designed,and the control of the inverter is realised through the PROFINET bus.In the control system,the PLC is the main control unit,the inverter controls the speed of the AC motor,and the human-machine interface(HMI)carries out the sending of control commands and the monitoring of the operation status.The control system has been successfully applied in a mixing plant,and the test results show that the system runs stably and reliably.
