Ethernet RJ45

The panel PC has two Gigabit LAN ports (X103, X104). 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 generation:

The Ethernet ports connected via PCIe with the i210/i226 controller are suitable for cycle times <= 1 ms and for distributed clock applications with 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 green when data transmission is in progress on the interface.

The green/orange LED shown in the figure indicates the data transmission rate.

The following table shows the LED meaning according to the possible data transmission speed:
