            Description

            The Profinet IO-Device switch needs to be configured with the real LineDelay per port. This contains the cable delay (pure runtime on the wire) plus the receive and Transmit Delay of the PHYs.

            However, current implementation configures a wrong value (20ns to short) into the switch which reduces in an unexpected offset in start of Red IRT period. This can be meassures by checking the Sync offset between different devics.
