Sorry image pointer was not correct for your third question. Please find the right image

Hello,

Thank you very mich for your prompt response. Please find my answers below :

1. Which version and build of QuickOPC are you using? (this is relevant because there was a related bug fixed).
5.80.347

2. Please start the OpcCmd utility (included with the product) and enter the following command:
uaSubscriber getService uaPubSubSniffer subscribeCapture opc.udp://239.0.0.1:4840 --ConnectionNetworkInterface "Ethernet 3"

This should capture all UA UADP communication (no filtering) on that interface&broadcast address.
What is the output please?


Question 3: In the Live Point Data (bottom part) of the Connectivity Explorer, please make the first column (Point) so wide that I can see the whole text, and post the image here again.


Please let me know if you need further info. Thank you once again.

Best Regards,
Vinoth

My goal : To build a C# WPF application as HMI to communicate with TwinCAT runtime via OPC UA Pub/Sub on UDP

Problem :
I am using OPC UA (UDP) PubSub in Beckhoff TwinCAT and publishing OPC UA datasets from Twincat runtime. I do not have PLC but I am running the PLC project on my local PC on Ethernet interface; my C# WPF application will also run on same local PC. please refer beckhoffSettings screenshot


In TwinCAT, I can see the packets being sent through nSendCnt in Diagnosis tab


And I can able to capture the data packets in wireshark.


In the next step,
Before going into code implementation, I wanted to test the communication with twinCAT runtime, using your tools and demo application. So I tried as mentioned below :
I tried using Connectivity explorer and used the uabinary file to test the live point data, I can able to Test PubSub Connection successfully but I cannot able to get the live data and received the following error message "No dataset message received within message receive timeout period (3000 millisec)" for each point or field.



I even tried using EasyOpcUAPubSubDemo application, I got the same results, I can test connection but I am unable to subscribe to the datasets and same error message "No dataset message received within message receive timeout period (3000millisec)"


I tried different options check many things but nothing helped. I have very short time to build my C# WPF application. It would be nice, If I get your support to resolve this problem to proceed further.

Thanks in Advance.

Best Regards,
Vinoth
