The main function of the 1756-EN4TR Ethernet module is to debug and debug the transmission signals on the Ethernet, converting the signals into effective data that can be recognized and processed by the CPU. The Ethernet module converts data transmitted on the network according to the TCP/IP protocol. The specific functions of Ethernet modules may vary depending on the manufacturer. For example, the ZS-Ethernet-801 embedded Ethernet module produced by Chengdu Zhongshan adopts an industrial grade design, has an ultra small size, supports TCP/UDP protocol bidirectional transparent transmission, TTL serial port to Ethernet communication, and adopts high-quality component configuration. In addition, Ethernet modules typically include data generation modules, UDP protocol header modules, IP protocol header modules, MAC protocol header modules, ARP request message modules, etc., to achieve data encapsulation and transmission. At the same time, in order to ensure the correct transmission of data, operations such as IP header parsing and ARP packet parsing are also required. When optimizing modules, it may also be necessary to consider issues such as sending scheduling modules, FIFO, and RDY signals to solve the scheduling problem of multiple inputs and one output, as well as the rate matching problem. In summary, the 1756-EN4TR Ethernet module plays an important role in Ethernet communication, responsible for data encapsulation, transmission, and parsing, ensuring the correct transmission and processing of data.
