  • Real-time industrial ethernet ethercat communication control
    Patent number: 8060677
    Abstract: A real-time industrial Ethernet EtherCAT system including a communication master and a plurality of slave nodes, wherein one slave node acts as a logic control master and the further slave nodes act as logic control slaves, and wherein a communication flow is as follows: the communication master sends a data fetching frame, when the data fetching frame passes through the logic control master, the logic control master inputs control data for the logic control slaves into the data fetching frame, when the data fetching frame passes through the logic control slaves, each logic control slave inputs status data into the data fetching frame, after return of the data fetching frame to the communication master, the communication master sends a data sending frame with output data, said output data being reorganized according to the control relationship between the logic control master and the logic control slaves by the communication master, when the data sending frame passes through the logic control master, the logi
