EtherCAT ports
The E1 and E2 Ethernet ports on the top panel of the MotiFlex e180 are used for
Ethernet fieldbus connections such as EtherCAT®.
In an EtherCAT network the E1 (IN) port must be connected to the master side of the
network. The E2 (OUT) port, if used, must be connected to the IN port of the next
slave device in the network:
Standard CAT5e or CAT6 Ethernet cables can be used.
