• Approach:

1. Establish a connection using basic setup without any security settings 
2. Proceed to configuring the security options as needed

• Prerequisites for validating the network connection:
  • Use a tool like PuTTY to test a Raw type connection to IP:49320 between the servers
  • Monitor with wireshark whether the TCP 3-way handshake is taking place as expected
• Server side configuration
  • Right click on the ex icon in the systray, and choose OPC-UA Configuration
  • On the Server Endpoints tab click Add
  • Choose the network adapter that this server should listen for OPC-UA traffic on
  • Make note of the url opc.tcp://<IP>:49320
    • Make sure that TCP:49320 is allowed by OS Firewall
  • Allow None in the security policy and certificates will not be checked for validation.
  • Open the server Configuration
  • Right click on Project in the tree > Properties > OPC-UA
  • Verify Server Interface Enable is Yes and Client Sessions Allow Anonymous is Yes
  • Click OK
  • From the menu bar choose Runtime > Reinitialize
• Client side configuration
  • Open the server Configuration
  • Right click on Connectivity and choose New Channel
  • For the driver choose OPC-UA Client driver, click Next
  • Click Next > Next
  • Use the url from the server as the Endpoint URL: opc.tcp://<IP>:49320
  • Set security policy to None
  • Take all the defaults for the rest of the channel creation
  • Click to add a device
  • Click Next until the option Select Import Items 
  • Click Select Import Items and pull in the items needed from the target
  • Last step is to click Next and Finish
