EIP Ethernet/ip driver connection error

[imhht1311]

I tried to communicate OMRON PLC using EIP Ethernet/IP Driver.

Two programs are same config.
example) Device driver is Allen-Bradley ControlLogix Ethernet, same IP address, same Slot number, same tag address

When Trying to communicate OMRON PLC using Kepware program, I received "Success: Connection Manager - Forward Open"
but When Trying to communicate OMRON PLC using WINCC OA program, I received "Connection failure: Connection Manager - Forward Open"

I want to communicate OMRON PLC using EIP Ethernet/IP Driver.

I used 'CJ2H-CPU64-EIP'

WINCC OA Version is 3.14 patch 31

Please Help me.

Please check the PVSS_II.log file for this project if an error is reported for the EIP driver when trying to establish the connection to the device.

I checked PVSS_II.log.
It said that "Connection error, EipStackWrapper, Stack error, *ERROR* Failed to start connected-mode session. Err: CIP Error 0X001: Connection Failure"

So, I used -dbg 2 try to find error.

and then, I compared between WINCC OA's Packet and Kepware's Packet using Wireshark.
