Use straight connections for the communications cables and connectors, as shown below.
Additional Information
There are two connection methods for Ethernet cables: T568A and T568B.
The T568A connection method is shown in the above figure, but the T568B connection method
can also be used.
Cable connections can be made freely in EtherCAT networks.
The following example shows daisy-chain connections.
Connect the communications cable from the EtherCAT master to the input port on the EtherCAT Slave
Unit, and then connect another communications cable from the output port on the EtherCAT Slave Unit
to the input port on the next EtherCAT slave.
Do not connect anything to the output port of the EtherCAT slave at the end of the network.
