Connection ZFX to Mitsubishi via Ethernet

Hello.
I have problem with reciving data from camera driver ZFX Omron on PLC Driver Q02UCPU. Mitshubishi ethernet module qj71e71-100.

I checked connection on wireshark and connected is ok.
But when I try send data from ZFX to Mitsubishi, data don't go.
Omron ZFX and Mitshubishi don't have any errors.

When I try send data in WireShark i have frames with Communication "TCP Dup ACK"

This is my connection from WireShark:
2 4.443592000 192.168.0.251 192.168.0.253 TCP mc3ss > vlsi-lm [SYN] Seq=0 Win=0 Len=0 MSS=2048

In PLC I use QFixBuffRcvActive to recived data.
PLC has ip address 192.168.0.251 and is it client TCP.
ZFX has ip address 192.168.0.253 and is it server TCP.

Thanks for any reply.
