[Note]:
Do not use multiple host computers in the same LAN environment. The industrial computer
with multiple network cards needs to be temporarily disabled without using network cards, otherwise
the host computer will appear abnormal (the same equipment is displayed many times, and no
equipment can be found)
The upper computer shields the wireless network card, so it must be connected with the network
cable to use the upper computer, and the wireless network card can be configured through the web
page.
4.7.5 Random native port
TCP client, UDP client, HTTP client and MQTT client can configure the native port to 0 (use
random native port), and server mode cannot use random port, otherwise the client cannot establish
connection correctly.
Using random port connection can quickly reestablish the connection when the device
accidentally disconnects the server, and prevent the server from rejecting the connection because
four waves are not completed. It is recommended to use random port in client mode.
The random port is automatically enabled when the device configures HTTP client, MQTT
client mode.
