AMT58x-EC EtherCAT®
6.1.3 Topology
Several topologies of connection are supported by EtherCAT
networks: line, tree, daisy-chain, star, ...). Furthermore EtherCAT
networks can be configured in almost any topology in the same
structure. The maximum length of the cable between two Slaves is
100 m; standard EtherCAT cables commercially available can be
used.
The choice of the topology depends on the structural characteristics
of the plant and it is made in order to reduce the complexity and time
for cabling.
Inside an EtherCAT network up to 65535 devices can be connected.
Some topology examples are shown in the Figures below:
