Hello. I think that i solved my problem. HW Config -> Properties Profinet IO System (Send Clock) change value from 1.000 ms to 4.000 ms. Also for all IO devices edit Update Time / Mode (Mode change value from Automatic to Fixed update time) (Update Time change value from 4.000 ms to 16.000 ms). No errors for 24 hours. Testing continues.
