Ethernet RJ45

The panel PC has two Gigabit LAN ports (X108, X109). The Ethernet standards 100Base-T, 1000Base-T and 2500Base-T enable the connection of corresponding network components and data rates of 100/1000/2500 Mbit/s. The required speeds are 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 generation:

The Ethernet port (X108, LAN1) connected via PCIe® with the i210/i226 controller is suitable for cycle times <= 1 ms and for distributed clock applications with EtherCAT.

The Ethernet port (X109, LAN2) integrated in the chipset with the i219 controller is 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 data transmission rate (Mbit/s). The LED (LINK/ACT) highlighted 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 green when data transmission is in progress on the interface.

The green/orange LED (SPEED) shown in the figure indicates the data transmission rate. The device generations differ in terms of the possible data transmission rate. The following tables show what the LEDs mean with regard to the potential data transmission rate.
