Poljachina Posts: 62 Rating: (0)	Hello all. I'm working with a S7-1200 - 1212 DC/DC/DC CPU and TIA basic v 11 + sp2 When I make a change in my code or if I add an element in my DB's and download it to the CPU the changes are not made, because in online mode those block are not identical and therefore I can not monitor these blocks, and can't work relay... If I compare the two block (offline to online), they are the same, even the green OK indicators are at every network. I have even deleted everything from the project and tried to download an empty OB1, but the same thing happens. The Offline block is not identical to the Online one... Could it be a faulty CPU, a bug in TIA portal. I have just started the repair funciton of the service pack 2 if it will help. Has anyone had a similar issue ? Any pointers would be great and appreciated. Thanks, best regards Ales

m_turk Posts: 25 Rating: (0)	I noticed that too.. Projects that are created earlier are working normaly... If you change them, and than continue, the problem starts.. But changeing the date doesn't help in my case :( Edit: It does help. You just need to change something in every block so that TIA compiles it again.. :)

Changed the system date on my pc. Did a compile all and download all files. Everything seems to work the only problem is the PLC tags do not match.

Poljachina Posts: 62 Rating: (0)	I've changed the date and everything started to work again... Frustrating, I lost 5 hours to this problem. I wish that I had posted this problem the first hour, maybe then half a day wouldn't be wasted. Thanks again guys for the solution!

Lenin Posts: 12 Rating: (0)	Hi I had the same problem today....sad I never figured it out it was 29/12 the problem....I lost all day and never tried changing system clock. However in the morning everything was working....until I changed something in my program and it all crashed. Hope someone get some fixes to TIA11, I have had some problems working with it.
