What is the best/recommended way to log a variable to see how its value changes as the system starts up?

I have been trying to do this by installing network trace, but it gets uninstalled as soon as I warm restart the PLC.

Thanks,

you can save the value of the variable, for example in TK1, into an array in each cycle, specifically into the next array element with each pass, and then view the contents of the array as soon as you go online.
