Abstract

Aiming at the problem that the current traditional fieldbus cannot meet the performance requirements of complex industrial environment, a solution is proposed using LAN9252 chip as EtherCat slave controller and ARM chip as microprocessor. First, the LAN9252 is used as the slave control module, responsible for data reading, writing and verification; the STM32F767 is used as the protocol processing module, responsible for protocol processing and communication of external servo devices. Secondly, realize the LAN9252 software design for data interaction between master and slave, and realize the STM32F767 software design for protocol processing of slave and protocol interaction of external servo. Finally, the slave test platform is built to test the communication function, real-time, stability and servo communication of the slave. From the test results, the EtherCAT slave of this design communicates normally with the master and external servo devices, and the slave refresh time is 15.75us, which can run stably for 14 hours. Therefore, the design can basically meet the performance requirements in complex industrial environments.
