Hi Mr. Wüstenräuber ,
Sorry for the late reply, I have not been around for a while.
I have tried as you said , however still same error.
In demo we have a FB12 activated in OB33
As test I have created a FB1730 activated in OB1
In WinCC I have tested both variants (FB12 and FB1730)
After that I have played with configuration parameters EXT_DP and PNIO, however in all cases just on main view some nodes goes from barred to error, but deep diagnose is never performed (error 0x8083)
I am attaching the last pictures.
However what is curious is that if I am changing first parameter Master_Nr from 100 to 64, communication stays OK, error 0x8083
If I am putting Master_Nr under 64 I get error 0x30a.
So this is really strange.
Anyway this new CPU combined with my inexperience in parameterizing diagnose block is getting wrong result.
Please tell me what are the chances for a test from your side with above hardware setup?
