I have done this to review saved data in an Application log, my program saves information into the application log, and retreives it to view on the screen, so you could adapt something similar.
It's a bit of a headache, as the data is saved in ASCII text, and you have to convert back into integers, but it's not impossible.
The heart of it is the Read_AppLog funtion in the Display Function Library, then you need to navigate to the record you want, decode it then use it.
I have found however if you read the application log with this function, you can not download to USB until you reboot the monitor, a limitation which is worth considering.
Good luck!
John.
