When using switches with fibre optic cable communication, distances can be
increased.
Only use industrial switches certified for Profinet and logically separate the Profinet
based automation network from the remaining IT infrastructure. In general, hubs
may not be used since this could lead to network collision. Based on existing network
load by office applications, uncoordinated mixing of office network and automation
network can lead to unpredictable problems with the Profinet application. For Profinet
networks as of conformity class CC-B, both points specified are binding.
The following topologies and combinations are possible using Profinet:
Devices in this topology only have one connection to the DCS (point-to-point) or to
the Ethernet switch (star).
Figure 2: Point-to-point or start topology
With this topology, devices and DCS are interconnected in series. To connect the
devices, no additional Ethernet switch is required
Figure 3: Line topology
If you interconnect several star structures, you obtain a tree network topology. Any
combination is possible
