Ethernet RJ45
The industrial PC has two Gigabit LAN ports (X112, X113). 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 must observe the following distinction:
The Ethernet port (X113, 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 (X112, 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 shown completely green 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 green/orange LED shown in the figure indicates the data transmission rate. If the speed is 100 Mbit/s the LED is orange, at 1000 Mbit/s it is green.
