      Description

      If the IP of the integrated LWIP task is changed via Hilscher specific netIdent protocol the Profinet protocol stack does not detect this IP change. Thus as a result acyclic Profinet communication is no longer possible.
      In this situation the Profinet protocol stack reports the wrong, old IP address via DCP and thus a new cyclic communication can not be established.
      Expected reaction is that the Profinet protocol stack detects this situation and delivers the real IP via DCP.
