3.3.8. Link Mode: Configure SE5001A in UDP

SE5001A 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 3.25 shows the UDP settings.

 Click on the

COM1 link on the left hand side.

 Select UDP.
Destination IP and Port: Specify the Begin and End IP here. Four groups of range IPs are allowed. This is

the IP address of the UDP program and the Port it is listening to. Note that the maximum number of UDP
nodes that SE5001A can handle would highly depend on the traffic load. We have tested that SE5001A can
handle up to 32 UDP nodes (baud rate 9600 bps, request interval 100ms, and data length 30bytes).

 Enter the Local Listening Port. This is the port that SE5001A should listen to. Match this setting in the

UDP program (usually called destination port in the UDP program).

Scroll to the bottom of the page and click on “Save Configuration” button to save the changes.

 Go to the section

3.3.16

to apply Pair Connection application if applicable. Otherwise go to the COM

Configuration (section

3.3.19

) for serial settings directly.
