Hello everyone,

I need help, I have project in Tia Portal V14 SP1 Update 6 with CPU 1515F-2 PN firmware 2.0, picture of network configuration in attach.

I have a problem with communication between equipments and CPU on profinet. For example screwdriver Deprag, I can commisioning it (start screwing, stop, etc.), but heartbit and state OK and NOK doesn't work. On Cognex readers is it the same, only part of communication is running.

Whole project is without errors, for transfer data I'm using DPRD_DAT, DPWR_DAT.

IF I use CPU 1511-1 PN and download the same project, everything works correctly.

So I think, that is something wrong in settings CPU 1515F-2 PN, but I don't have idea what.

Do you have some ideas?

Thanks a lot for answer.

Martin
