The OPC-UA module shows information about OPC-UA binary protocol traffic on Layer 7 and performs reponse time measurement of related requests and responses.
A PCAP button allows for capturing OPC-UA binary protocol traffic.
The statistics table shows traffic counter of all OPC-UA binary protocol packets. The traffic graph shows both unencrypted and encrypted traffic. For unencrypted requests and responses following counters are provided and displayed in the second graph:
- Unanswered requests: Requests that were not responded within a timeout of 60 seconds or until end of connection.
- Unrequested responses: Responses without corresponding request.
- Duplicated requests: Requests that have been already seen. This could be due to a TCP retransmission.
- Service faults: Service faults of the OPC-UA server.
Requests and responses are correlated based on the security request id. Response time measurement is performed between them and displayed in the table and in the third graph.
