Research on Performance of Control System Based on EtherCAT
Aiming at the increasing demand of performance for industrial control, the industrial real-time Ethernet control system for high-speed control based on EtherCAT was presented. The principles and frame structure of EtherCAT were introduced. The system response time, EtherCAT cycle time and oversampling technology of achieving microsecond-order sampling were analyzed. By designing the experimental platform based on EtherCAT, The system response time, EtherCAT cycle time and oversampling performance were tested. Theoretical analysis and experimental test results show that the System can achieve millisecond-order response time and microsecond-order oversampling cycle time. Therefore, Industrial Ethernet control system based on EtherCAT is very suitable for high-speed control and real-time data acquisition.
