Ethernet RJ45

The industrial PC has three Gigabit LAN ports according to IP65/67 (X103-X105). The 100Base-T, 1000Base-T, and 2500Base-T Ethernet standards 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 industrial PC may only be connected to internal Ethernet networks and not to external telecommunication networks.

The data rates of the Ethernet interfaces and the use of the controller vary depending on the device generation. The following table shows classification according to the device generation:

The Ethernet ports are suitable for cycle times <= 1 ms and for distributed clock applications in EtherCAT.

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. 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.

Since the LEDs directly at the interface cannot be seen with an existing wiring, the LEDs on the side panel of the PC (see Fig. 6) show the status of the Ethernet interfaces.
