Waveform Chart stopped to update data on the GUI.
The LabVIEW 2020 code runs on CRIO-9047 RT target, acquires Thermocouple data and RS232 data from another device every 3 seconds. The application runs for upto 10 days sometimes more.
The waverform chart does not update the data very randomly, it starts to update after clearing the chart data manually. I do not think this is chart history length issue, as the history is set to 1000000 and the update had stopped in multiple incidents during the test. Sometime within 1 hour after clearing the chart data, sometimes after 5 days. Sometime never during the 10 days of test.
My requirement is to show all the data throughout test duration and check the history anytime.
The application is running normal, all the logs are properly stored in a textfile; storage location is on USB stick of CRIO. No issues with acquition and logging of the data, even when the chart data does not update.
The see this issue frequently after the PC is connected to multiple other network devices (3) through Ethernet.
Could you please suggest some solution?
Is there a way to monitor any buffer data of the chart to identify when exactly the issue occurs or before?
Since the incidents are very dynamic, How do I recreate the issue to address it with different solutions and test quicker instead of waiting for days to validate if any change is fixing the solution?
The application uses queue for data transfer between loops. I use local variables as well. The code is not optimized, may be.
Does it help if I use exe instead of developement code to execute? Just thinking.
I can provide more details if required.
