Abstract: Real-time control network is an important supporting technology for the new network and intelligent industrial equipment. Based on the study of POWERLINK real-time industrial Ethernet protocols, this paper takes FPGA as the core to design and implement an embedded hardware node of real-time wireless communication. Among them, as the processing unit of real-time network protocol stack, FPGA interacts with main control unit to realize high speed?data exchange through the parallel interface, and implements the transmission interface of wireless data based on the typical RF module, which can support high-speed transmission of wireless data. Through the integration of real-time link layer management mechanisms of POWERLINK IP core, it has achieved the wireless real-time transmission of data between multiple nodes in the industrial networks.
