W&T
In addition to TCP/IP commands the device can also reply to
UDP datagrams. Here you need to set the local Port you want
the device to listen to. The factory default setting is 42279. The
Remote Port default is AUTO for answering to Source Port.
In special cases Web-IO have to answer to defined port that is

application
Here is an overview of applications and operating modes for
