Abstract

EtherCAT is a real-time Ethernet protocol for factory automation applications that enables periodic data exchange with cycle times of few microseconds thanks to the capability to process frames “on-the-fly”. EtherCAT does not provide efficient mechanisms for enabling the transmission of asynchronous real-time data from slave nodes. This paper proposes an EDF-based Swapping Approach that allows slaves to send real-time asynchronous traffic over EtherCAT networks in an efficient way, while maintaining the interoperability with standard devices.
The paper describes the EDF-based Swapping Approach and presents a comparative performance evaluation with both the EtherCAT standard and another approach in the literature that exploits CAN-Like arbitration.
