Problem with Variable Table in SIMATIC Manager

Hello everybody.

Lately, I have been using an S7-300 to do some analog data logging.
The analog readings are chronologically stored in a DB with about 30 rows. Then I read the 30 stored values on my computer with a Variable Table online, I press Ctrl+A to select them all and Ctrl+C to copy and save them to an Excel file.

Today I need to save 200 rows. The values are correctly stored in the DB but when I try to read them in the Variable Table I can only see the ones that fit on the screen. If I scroll down in the Variable Table the other values show up but the previous ones disappear, so when I press Ctrl+A and then Ctrl+C only the values that I can actually see on the screen are copied.

Is it possible to real-time monitor also the values that do not fit on the screen, so I can copy all at once?

Thank you, and have a nice day.

If your problem is data consistency, just save your values in a DB on raising edge.

Then get DB data as you would get your data with your table. But it will be consistent.

If it is just copy/paste issue, you may automate it for a large table with pc automation Tools like AHK.

It works only in a limited way.

What you can do is either save the data with program (to memory bytes/bits) or try to save the DB from online view to an offline project.
