Ethernet RJ45

The six additional Ethernet ports enable the connection of appropriate network components with data rates of 100/1000 Mbit/s in accordance with the Ethernet standards 100Base-T and 1000Base-T. 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 Ethernet ports are suitable for cycle times <= 1 ms and for distributed clock applications in EtherCAT.

The Intel® i210 (MAC/PHY) is used as controller for all six ports.

The LEDs of the LAN interfaces indicate the activity and the speed of the data transmission (Mbit/s). The respective lower LED 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 respective upper LED indicates the speed of the data transmission. If the speed is 10 Mbit/s, the LED is not lit. At 100 Mbit/s the LED lights up orange, at 1000 Mbit/s it lights up green.
