Evaluation of the μController Networks Communication for EtherCAT Process Data Interface
Authors: , , , , ,
Abstract: According to the EtherCAT process data interface networks system designs, we determined that the Synchronous and Asynchronous µController scheme evaluations based on the FPGA state machine algorithm. The present study focuses on the Schematic of µController interconnection between FPGA and ESC based on the VHDL state machine algorithm, which includes state machine programs. In addition, the performance of the Synchronous and Asynchronous µController was verified through numerical simulations. Furthermore, we found the simulations gave further evidence that the 16 bits synchronous and Asynchronous µController signals can satisfy the two write access and a read access requirements for the EtherCAT networks communication. Finally, the results include the positive and negative aspects of the Synchronous and Asynchronous µController networks communication, and the comparison the results of the Synchronous, Asynchronous and SPI communication evaluations done by the researchers.
