Table 24: EtherCAT Out Connector
When connecting several EtherCAT devices in a network, the EtherCAT master must always be
the first device in the network. The output of each device is connected to the input of the next
device. The output of the last device may remain disconnected. If redundancy is required, the
output of the last device should be connected to the input of the EtherCAT master.
