7.1.3 UDP Mode
UDP is a faster but connectionless network protocol; it does not guarantee the delivery of
network datagram. The SE5416A Series can be configured to transfer data using unicast or
multicast UDP from the serial device to one or multiple host computers, data can be
transmitted between serial device and host computer in both directions.
There is no server or client concept on this protocol, they are called peers or nodes. So here
you only need to specify the Local Port that we should listen to and specify the Destination
IPs of the remote UDP nodes.
Figure 7.5
SE5416A Series also supports connectionless UDP protocol compared to the
connection-oriented TCP protocol. Please be aware that even though UDP provides better
efficiency in terms of response time and resource usage, it does not guarantee data delivery. It
is recommended to utilize UDP only with cyclic polling protocols where each request is
repeated and independent, such as Modbus Protocol; Figure 7.6 shows the UDP settings.
