LAN connections
LAN interface (X000/ X001)
The CX50x0 systems have two independent LAN interfaces. Both ports are able to operate at speeds of 10 / 100 /
1000 Mbit. The LEDs on the left-hand sides of the RJ45 sockets indicate the status of the LAN connection. The upper
LED indicates whether the port is connected to a network. If this is the case the LED is yellow. The LED flashes if
data traffic takes place on the port. The lower LED indicates the connection speed. The LED is green if the speed is
10 or 100 Mbit. In 1000 Mbit mode (Gigabit) the LED is red.

Note
Independence of the ports
Both ports are independent of each other. In contrast to the CX1020 and CX9000 systems,
no
switch is integrated. For a line topology an additional switch is required. The
independent ports can be configured in different ways:
 The upper port (1) is configured as Gigabit IT port,
 The lower port (2) is configured for EtherCAT communication
in the delivery state.
