Regarding Connection Aborted Error Exception at OPCUA Python Data Logging Client

[rajnishnationfirst]

Hi Team ,

I have developed a data logging using opcua hda .

Scenarios :

Data Logging Acquisition Cycle set at WinCC OPENPCS Is 500 m/s - 120 Data Points in 1 Minute .

I am fetching 1 hour day for a certain interval data points ( 7200 Data points for 1 hour ) but i am facing issue using hda_client.read_raw_history(start_time , end_time ) function.

There are 20 main nodes with each having 100 tags .

For each node a thread is created using THREADPOOL EXECUTOR in python for data logging. For 1st 1 hour i am able to fetch the data points 7200 but when i am fetching for next hour its throwing an exception as - ConnectionAbortedError .

Image Snapshot Reference :

I have also increased the timeout parameters in client.py as below :
Client.py

Do i need to change also somewhere in ua_client.py or do i need to do anything next.

Thanks
