            Description

            When the Profinet Device has more than 150 byte output data or the frame size of output IOCR exceeds 170 byte, IRT communication might be not established or unstable. The problem is caused by wrong internal timing which does not consider the frame reception time. The issue might also affect the Profinet Controller when large Input IOCRs are used in conjunction with only a few devices.

            Unfortunately a similar issue was already addressed in PSPNCORE-495 but not fully fixed.

            The fix for this issue may have an impact on T_IO_OutputMin of applications.
