Ethernet RJ45

The panel PC has an Ethernet RJ45 interface (X102) in the form of a push-pull Ethernet built-in socket. The Ethernet standards 100Base-T, 1000-Base-T and 2500Base-T enable the connection of corresponding network components and data rates of 100/1000/2500 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 controller is used as follows, based on the device generation:

The Intel® i219 Ethernet port is suitable for real-time Ethernet applications with cycle times > 1 ms (without distributed clocks).

The Intel® i226 Ethernet port is suitable for cycle times <= 1 ms for distributed clock applications with EtherCAT.

The LEDs of the LAN interfaces indicate the activity and the data transmission rate (Mbit/s). The LED (LINK/ACT) 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 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 the LED meanings according to the possible data transmission rate.
