Network topology for POWERLINK
Inside the segment only Ethernet hubs may be used as infrastructure elements. The hubs must
meet the requirements on class II repeaters acc. to IEEE 802.3u.
Class I hubs and switches are not permissible since they have considerably longer delay times for the
frame forwarding and a bigger jitter. Both sizes reduce the real-time capability and dynamics.
The cable length between both nodes is limited to 100 m.
