Why don't you screencapture your settings so we can check it.

there are no other devices connected to the switch, only the laptop and 3 modbus are installed, but when the master and the first slave are working, the second slave cannot  pinging , after being removed from the switch and  installed directly into QJ71 without the hub being connected

Master .

Cpu  IP = 192.168.3.30.

QJ71MT91  IP = 192.168.3.40

SLAVE 1.

CPU IP = 192.168.3.50.

QJ71MT91 IP = 192.168.3.60.

SLAVE 2.

CPU ( Q02 H CPU ).

QJ71 MT91 = 192.168.3 70

I've tried it, without a CPU connection to Ethernet,But still problem

Until now my problem about Qj71mt91 has not been resolved and I have contacted a technician from the Mitsubishi agent but it has not been resolved either 😑😑😑

The only thing i can think of which should be not possible is that you have devices with the same MAC adress.
