Analysis of Industrial Ethernet used in Active Surface System of QTT

Abstract Industrial Ethernet is widely used in automation and control system because of its high reliability and good communication performance. There are several protocols for Industry Ethernet. In different applications, it is necessary to select a appropriate protocol standard according to different needs. In order to apply industrial Ethernet in the active surface system of QTT, the control network requirements of active surface system were summarized. The period and jitter of three protocol standards, Ethernet/IP, Profinet RT and EtherCAT, were tested by evaluation hardware. The differences between network configuration and ring redundancy settings are analyzed. The results show that EtherCAT is more suitable for the network application requirements of active surface system of QTT.
