Hello AutoGen_961606

if you want to trigger something with value change then you have to use an external tag and use the acquisition cycle "cyclic continuous" only then the trigger will work properly every time in every screen.

To your usecase-> do I have understand correctly? you want to log values (i´m not sure if cyclic or on demand; you can do both by setting it and useing systemfunction for example)

If you want to save the logged data after the batch I would use the following Link to create a copy of the logged data: LINK

and then after this, delete the log (systemfunction) and start again with the new log/batch

If you need specific help then write where you struggle and what you have done so far or if I missunderstood yoiur use case, then perhaps you can explain with other words
