Hmi with fx3u unit

I can connect fx 3u with computer successfully. But not with a weintek hmi 8103ie via Ethernet. Serial communication works fine. Why Ethernet can't detect hmi. Using fx3uenet adp with a hub. also when I put a tggle switch on hmi to hold an input that don't work but momentary switch works fine.

Have you configured the Ethernet as shown in the PLC connection guide?


It is available here as the first search result https://www.google.com/search?q=plc+connection+guide+weintek

All options tried out. The PLC connects with pc the hmi connects with pc but they don't talk to each other(pLC N HMI) OVER ethernet.serial Conn. Is fine.

I've had Weintek screens work fine over Ethernet using the Weintek guide.


How do you have everything configured? Post here then I can compare it with mine and see if there's any difference.
