Question

Connect PLC to Kepware through Ethernet Module

PLC type: Mitsubishi Fx5U

Ethernet Module: USR W630 (Wi-Fi to serial)

The proposal PLC connects directly to Kepware through the Ethernet port and is working fine, and I want to try to connect through the Wi-Fi.

My diagram is PLC - ethernet → USR W630 ))) Wi-Fi → Kepware.

The purpose of the Ethernet module is to work like an Ethernet bridge. I follow this link to set up the PLC: https://industrialmonitordirect.com/blogs/knowledgebase/mitsubishi-fx5u-kepware-slmp-connection-configuration?srsltid=AfmBOop2S78y27FdOU68Ot9BDMhwFP3ieD8WG3x2a4zojZ9K_RskSMqR.

In Kepware, I tried using the Mitsubishi Ethernet method to set up it, but it always shows that the reading is failing. I tried with this tutor. 

The problem is when I tried through Modbus TCP/IP to reading the PLC values. It looks like no problem, and I got the value of the PLC address. 
Does everyone have these problems, or any suggestions for my situation? Thank you first.
