Hi

Are you certain that the PLC program is the same both Off- & On-line?
In "Simatic Manager", go to menu "PLC" -> "Upload Station to PG", and upload everything from PLC to your computer.
(It's better to do that in a new project)

Then, go Online with what you just downloaded.

Then compare this with the program you're now trying to go Online.

NEVER, NEVER, NEVER, NEVER BE SURE!
ALWAYS DOUBLE CHECK AGAIN & AGAIN & THEN SOME MORE!
FINALLY, CHECK ONCE MORE BEFORE YOU DO ANYTHING!

Maybe you should install HW updates?
