Yes, i am curious if there is any chance for direct connection S71200/1500/S7-300/400 to a server for reading /writting to DB .

i have seen it is possible via WinCC, are few examples, but i have senn some movies where are direct connection to a DB.

Is more interesting direct connection.
If you/ somebody else have some example, this i am intereste to learn.
Thank you in advance
