This yould be: - Maximum cycle time exceeded - Time of day interrupts skipped by moving the time forward - Delay too great when processing a priority class You can find more informations regarding OB 80 in the online help of Simatic manager.

Silent Bob Posts: 836 Rating: (100)	Hi, unfortunalty I can't download your project. Can you somehow identify wich block is causing the error? Maybe you could try to move each runtine group into another cyclic interrupt OB. If you move them one by one (move one, compile, check if error occures, move next, check, ...), you shold be able to identify the runtime group where the fault causing block is inside. If you know this RT group you can start to movesingle blocks until you have the bad block. This is maybe one mothod to find the block wich is causing the error.

But i cant found this RT group, diagnostic buffer said- we got a problem from OB80, but didt say where (RT group,chart)- i have many RT groups in OB35. May be i can upload this file in another file depot.
