Hi. We are installing a trial verison of Kepware on our VM Hyper-V to see if the OPC server is working before we are ordering a license. But i just getting bad quality from the Mitsubishi PLC. The server is a 2019 windows server. When im trying from my Windows 11 computer is working with no problem. I have disabled anti-virus, firewall everything and still not working.

Any suggestions?

It should work fine on Hyper-V also unless demo time(2 hour) not expired or if there is no any networking issue.  

  • 2 hour period can be reset by stopping and then starting the KEPServerEX

Please Check if you can Powershell Test-NetConnect to the device on the port KEPServerEX is trying to use.
Powershell has a built in commandlet that can help prove or disprove TCP socket connectivity
Command Syntax: Test-NetConnection [host] -Port [port number]
Example: Test-NetConnection 255.255.255.255 -Port 502
If these do not succeed this issue is networking.

 

Also  check disabling ECN on 2019 windows server.Please refer below article to disable it

  • When Explicit Congestion Notification (ECN) is enabled, some older devices will drop or reject the packets because of the manipulated header

If above won't work, I would recommend you to capture the traffic (packet) using tool Wireshark(free) and check why it is not working. 

If the issue persists; I recommend opening a support ticket with the Kepware Technical Support team. Here is a link to the my kepware login page where a ticket can submitted:
