  4. PROFINET: Netwerkinfrastructuur Koper draad • Standaard ethernet infrastructuur met: • RJ 45 Connectoren • Kabeltype Cat 5e , folie & shielding! • Maximale kabellengte 100m Isolatie van de draad Binnenste beschermlaag Plastic folie Middenste opvulelement Afschermfolie Afscherming Buitenste beschermlaag Pushing Performance De PROFIBUS, PROFINET & IO-Link dag 2011

  5. Full duplex Switch Switch Switch • 100 Mbit/s • 4 wires, twisted pair, shielding en folie • Full duplex: zenden en ontvangen tegelijkertijd Pushing Performance De PROFIBUS, PROFINET & IO-Link dag 2011

  6. Topologiën: Lijn • Geïntegreerde switches • Lagere beschikbaarheid: falen van 1 toestel! • Belasting halveert door keuze plaats vd PLC in de lijn Pushing Performance De PROFIBUS, PROFINET & IO-Link dag 2011

  7. Topologiën: Ster • Centrale switch • Hoge beschikbaarheid (switch met redundante voeding) • Belasting: lijn naar controller is meest belaste punt Pushing Performance De PROFIBUS, PROFINET & IO-Link dag 2011

  8. Topologiën: Boom • Meerdere switches  Gestructureerd netwerk • Hoge beschikbaarheid: (switch met redundante voeding) • Belasting: lijn naar controller is meest belaste punt Pushing Performance De PROFIBUS, PROFINET & IO-Link dag 2011

  9. Topologiën: Ring • Hoge beschikbaarheid: Redundantie  Media Redundancy Protocol • Switches  1 Redundancy manager + ... redundancy client(s) • Belasting halveert door keuze plaats vd PLC in de lijn Pushing Performance De PROFIBUS, PROFINET & IO-Link dag 2011
