9 Device Connections and Switches
9.1 Ethernet
Interface
RJ45 plugs or M12 plugs are used for the Ethernet interface.
•
For RJ45 connector, use twisted pair cable of category 5 (CAT5) or
higher, which consists of 4 wires twisted in pairs and has a maximum
transmission rate of 100 MBit/s (CAT5).
•
For M12 connector, use Category 5 (CAT5) or higher cable with a
maximum transfer rate of 100 MBit/s (CAT5).

Ethernet Pin Assignment at the RJ45 Socket
Note:
The device supports the
Auto Crossover
function. Due to this fact
RX and TX can be switched. The following figure shows the RJ45
standard pin assignment.

Further Notes:
(1) The RJ45 socket is only for use in LAN, not for telecommunication
circuits.
(2) With loaded EtherCAT Master firmware only the RJ45 channel 0 can
be used, channel 1 is deactivated. Beginning with the EtherCAT Master
firmware version 3 channel 1 can be reactivated if redundancy is
activated. For the Open Modbus/TCP firmware with V2.3.4.0 and higher
both RJ45 RJ45 channels can be used.
