Product overview
C6920 11 Version: 3.2
3.2.2 Ethernet RJ45
The C6920 has two Gigabit LAN ports (X102, X103). 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.
The controllers are used as follows, based on the device generations:

Generation Controller
C6920-0050 Intel
®
i218 for LAN1 and i210 for LAN2
C6920-0060 Intel
®
i219 for LAN1 and i210 for LAN2
C6920-0070 Intel
®
i219 for LAN1 and i210 for LAN2
The Ethernet port i210 connected via PCIe is usually suitable for cycle times <= 1 ms and for distributed
clock applications with EtherCAT.
The Ethernet port i219 integrated in the chipset is usually suitable for real-time Ethernet applications with
cycle times > 1 ms (without distributed clocks).

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