Description of the interfaces
CX20x2 20 Version: 1.7
5.2 Ethernet RJ45 (X000, X001)
The two Ethernet interfaces are independent; no switch is integrated. The independent Ethernet interfaces
can be configured in different ways. In delivery state the Ethernet interfaces (X000, X001) are configured for
EtherCAT communication.
Note that an additional switch is required for a line topology.

Both Ethernet interfaces reach speeds of 10 / 100 / 1000 Mbit. The LEDs on the left of the interfaces indicate
the connection status. The upper LED (LINK/ACT) indicates whether the interface is connected to a network.
If this is the case the LED is green. The LED flashes when data transfer is in progress.
The lower LED (SPEED) indicates the connection speed. The LED does not light up if the speed is 10 Mbit.
The LED is green if the speed is 100 Mbit. The LED lights up red if the speed is 1000 Mbit (gigabit).
