Description

technical field [0001] The invention relates to a device and a method in the field of network technology, in particular to a gateway device between EtherCat industrial Ethernet and wireless Zigbee and a protocol conversion method thereof, belonging to the field of communication technology. Background technique [0002] Real-time industrial Ethernet EtherCAT technology is a general ultra-high-speed Ethernet field bus technology developed in recent years, which is used to replace PROFIBUS, CANopen, and MODBUS industrial bus technologies. The so-called industrial field bus is to make data acquisition devices, that is, field instruments and control units, interconnected through the bus to realize data acquisition, analysis and automatic control. [0003] The EtherCAT protocol is an extended Ethernet system based on the IEEE802.3 standard, which enables predictable timing and high-precision synchronization in data transmission. The traditional Ethernet media access control metho...
