OPC Client Missing Values #1

Open Mujaved opened 5 years ago

Mujaved commented 5 years ago

Hi , I do not have any wire-shark trace but when i have reconnected again i got the current value. Initial if it is started with the 1 value then after reconnect i got 150. So it means 149 values missed. I just want to understand what can be the route cause for this. My client is working fine from 6 months no data loss but suddenly it behaves like this. Let me know the possible route causes for same.

Thank you

Moin, don't understand. I hope, you don't assume that the client works like a 'message queue', right? So, after a reconnect, it is really possible, that you are missing values!

Cheers.

Its Mujaved, Apologize describe situation as follows I have configured around 100 tags with the opc ua c# client. This is realtime data which will come every 1mint frequency. I have tested no issues getting all tags changes correctly for 15 days. After that i have missed only two tags changes values i can see in machine it is changed but not received at client level remaining 98 tags are fine working. Now i have restarted and that two tags also getting fine. I need to understand what are the possible route cause for this or support me how i can proceed for RCA.
