Details
I am encountering an issue connecting Process Simulate to a PLC via an external OPC-UA connection to localhost:4840 and also localhost:48050 (gateway). I was able to get this working on my laptop (Windows 10), but am now transferring the project to my Windows 7 Enterprise desktop. Process Simulate fails to connect to localhost or even the local gateway that I have setup. I am using UAExpert (Client) to also browse for the same tags on localhost, and it can see the server and browse the tags with no issues. I've checked firewall settings for both ports and they present no issue (even compared firewall settings between my laptop and desktop and I've double checked that everything is configured correctly.)
Solution
The issue was not related to Process Simulate, but rather it was a DNS configuration parameter that was not pointing at the correct host name.
After fixing this to point to the correct host name, the OPC UA connection worked with no issue.
