The EtherCAT connection is established via the RJ45 sockets X246 (IN) and X247 (OUT).
A standard Ethernet patch cable is suitable for connecting the communication module to the
EtherCAT fieldbus.

Pin assignment of the RJ45 sockets
Tip!
The EtherCAT interfaces are provided with an auto MDIX function. This function adjusts the
polarity of the RJ45 interfaces so that a connection can be established irrespective of the
polarity of the opposite EtherCAT interface and irrespective of the type of cable used
(standard patch cable or crossover cable).
Note!
To prevent the RJ45 socket from being damaged, insert or remove the Ethernet cable
connector straight (at a right angle) into or from the socket.
