Hi guys,
I'm trying to connect a Plant Scada ver 8.4 OPC UA server to ignition but having connection reset java.net.socketexception error.
I've also checked the port of the opc server is open. Not sure if I did anything wrong. Any insights would be appreciated!
Connection reset means the connection is being closed by the other side.
Usually a firewall issue, sometimes it means the service isn’t actually running, sometimes other things.
Nothing wrong on the Ignition config yet. You probably wouldn’t be able to connect e.g. UaExpert from the same server Ignition is on either.
Thanks Kevin for quick response.
I'll start to look at firewall stuff first.
Do I need Kepware in my case?
You don’t need Kepware for anything you’ve shown or mentioned here.
Thanks.
I'm not the IT expert! Silly question, if you can Test-Netconnection to the opc port of target opc server, and it comes back with the TcpTestSucceeded:True as picture below, you would think it can somehow talk to target opc server over firewall?
Yeah, might not be firewall, might be the actual server itself closing the connection for some reason.
Try UaExpert. I don’t expect that to work, but if it does, Wireshark might let you make a comparison and figure out why.
