Ethernet RJ45

The panel PC has two Gigabit LAN ports (X108, X109). The 100Base-T and 1000Base-T Ethernet standards
enable the connection of corresponding network components and data rates of 100/1000 Mbit/s. The
required speed is selected automatically.
The RJ45 connection technology with twisted-pair cables is used. The maximum length of the cable
connection is 100 m.
If you use the Ethernet ports with EtherCAT or for Real-Time Ethernet applications, you have to regard the
following distinction:
The Ethernet port (X109, LAN2) connected via PCIe with the i210 controller is generally suitable for cycle
times <= 1 ms and for distributed clock applications with EtherCAT.
The Ethernet port (X108, LAN1) integrated in the chipset with the i219 controller is generally suitable for
EtherCAT and Real-Time Ethernet applications with cycle times > 1 ms (without distributed clocks).

The LEDs of the LAN interfaces indicate the activity and the data transmission rate (Mbit/s). The LED on the
left in the figure indicates whether the interface is connected to a network. If this is the case, the LED lights
up green. The LED flashes when data transmission is in progress on the interface.
The LED on the right in the figure indicates the speed of the data transmission. If the speed is 100 Mbit/s the
LED is orange, at 1000 Mbit/s it is green.
