If thedata is not from this channel, the data will not be received by E810-DTU (CAN-ETH).(3) In UDP Client mode, the target address is set to 255.255.255.255, which can achieve the effect of UDP fullnetwork segment broadcasting, and also can receive broadcasting data. E810-DTU (CAN-ETH) supports broadcastingwithin network segment, such as xxx.xxxx.255 broadcasting mode.4.1.10. UDP Server function(1) UDP Server means that the source IP address is not verified on the basis of ordinary UDP. After receiving a UDPpacket, the target IP is changed to the data source IP and port number. The data is transmitted to the nearestcommunicated IP and port number.(2) This mode is usually used in data transmission scenarios where multiple network devices need to communicatewith modules and do not want to use TCP due to faster speeds.Note: UDP Server cannot send data actively, and can only send data to the IP and port that has recently performeddata interaction after receiving the data.
