5.1 Appearance and Parts Description
• The CPU has an integrated Ethernet communication processor with EtherCAT controller.
• You can use the EtherCAT controller in an EtherCAT system as an EtherCAT MDevice .
• It is connected via the integrated EtherCAT port X5.
• Connect this interface with the RJ45 jack "IN" of your EtherCAT SubDevice station.
• EtherCAT uses Ethernet as transfer medium. Standard CAT5 cables are used. Here distances of about 100m
between two stations are possible.
• An EtherCAT network always consists of an EtherCAT MDevice and a various number of EtherCAT
SubDevice.
• Each EtherCAT SubDevice has an "IN" and "OUT" RJ45 jack. The arriving EtherCAT cable from the direction
of the MDevice is to be connected to the "IN" jack. The "OUT" jack is to be connected to the next station.
With the respective last station the "OUT" jack remains free.
(4) Ethernet port X3/X4
These connectors are used to connect devices compatible with Ethernet communications.
Connectors X3 and X4 by default are switched together.

• The CPU has an integrated Ethernet communication processor.
• The connection happens via an integrated 2-port switch (X3/X4).
• Via Ethernet (default: 192.168.1.1, [MAC1]) you have access to:
– Programming / remote maintenance of the CPU.
– Web-based management WBM of the CPU.
– OPC UA communication of the CPU.
• In the optionally available [PROFINET IO controller] operating mode, you can connect your PROFINET
devices here.
• In the optionally available [PROFINET I-Device] operating mode, you can connect your CPU as I-Device to a
PROFINET IO controller here.
