5.2.1 Network topology
An EtherCAT telegram is sent through a pair of wires from the master to the slaves. The
telegram is forwarded from slave to slave until it has passed through all the devices.
Finally, the last slave returns the telegram to the master through a second pair of wires. In
this way, EtherCAT always forms a logic ring topology, independent of the topology
selected.

 The devices are interconnected successively.
 Correct assignment and wiring of the EtherCAT inputs (IN) and EtherCAT outputs (OUT)
is required for proper operation.
 The direction of data transmission is from the master to the slaves.
