c - Capture OPC-UA data using Wireshark

Question

I have established a connection between OPC UA server and client.I have set the security policy to none mode.I am able to view the opc ua nodes/attributes value updating in the Unified Automation application.I could trace the opc ua communication in Wireshark too. However, when I click on the ReadRequest or ReadResponse messages and expand the frame,I don't see the node id or node values in wireshark.There is only timestamp value visible.Could anyone help me how can i see the requested node/attribute id and value in wireshark.

Answer 1

What do you see if not this? Have you dug down into the ReadRequest structure?
