Datalogger RT problem

I am trying to set the RT datalogger functionality. The variables GDS that i have to save are also OPC-UA variables, i have Node-red installed on the PLC and Node-red can read or write these variables. I have some problems because sometimes the datalogger stop working and does not recover. In attached my .xml file that i use to create the Database, maybe i’m wrong with something. I have read all the informations on the GitHub but it seems all ok in my file. I have also tried to check the Output.log file but there is nothing related to some Datalogger error I am using software version: 2020_0_1_LTS Could you help me with this problem? XML FILE

Hello Pietro, sorry for the late response.

Do you modify the Database or open it from the outside without copieing it?
You might block the write access of the Datalogger in that case…
When the Datalogger stops working for you, the aplication is still running fine right?
How long does it usually take for the Datalogger to stop?
kind regards,
Oliver
