4.2.3.UDP server mode

UDP Server means that the device does not verify the data source IP address when

communicating with UDP protocol. After receiving a UDP packet, it saves the source IP

address and source port of the packet and sets it as the target IP address and port.

Therefore, the data sent by the device only sends the data packet to the source IP address

and port of the last time the device received the data.

This mode is usually used in scenarios where multiple network devices communicate

with this device, and the frequency is high, and TCP Server cannot meet the conditions.

Using UDP Server requires remote UDP devices to send data first, otherwise data

cannot be sent normally.

[Note] In UDP mode, the data sent by the network to the device should be less than 512Bit

per packet, otherwise it will cause data loss.

UDP Client is a connectionless transport protocol that provides simple and unreliable

transaction-oriented information transmission services. There is no connection

establishment and disconnection. You only need to configure the destination IP and

destination port to send data to each other. Usually used in data transmission scenarios

where there is no requirement for packet loss rate, the data packet is small and the

transmission frequency is fast, and the data is to be transmitted to the specified IP.

In UDP Client mode, the device will only communicate with the configured (target IP and

target port) remote UDP device.

In this mode, the target address is set to 255.255.255.255, and the transmitted data will

be broadcast in the whole network segment, but the receiving and transmitting equipment

needs to ensure the port consistency, and the equipment can also receive the broadcast

data.
