Hello, I would like to set up communication between two KEP Servers KEP Server to KEP Server.
Currently, the other KEP Server is reading tags from our server,
but we are unable to read their tags.

Our current license status is as shown below.
Do we need to purchase a separate OPC UA Client?
If so, how much does it cost approximately?

Best answer by Bhupendra

we can configure an OPC UA to tunnel from one KEPServerEX / ThingWorx Kepware Server (KSE / TKS) server to another KEPServer 

Resolution
  • 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
