Communication Connections
NOTE
Be aware of the safety instruction in chapter Safety Notes, Page 188.
If you do not connect cables to the communication connectors, Siemens recommends covering the connec-
tors with a cap or dummy plug (not included in the delivery) to prevent the contacts from becoming dirty.

(1) Ethernet interface Z
The device is equipped with 1 Ethernet interface. The data are exchanged via the RJ45 plug connector.
Further Technical data see chapter 12.1.3 Communication Interfaces.
The device features an internal Ethernet switch. It is therefore possible to connect a Y-cable to the Ethernet
interface in order to cascade devices with an Ethernet interface. You can enable or disable the internal
Ethernet switch in the parameterization. If you use a Y cable and the internal Ethernet switch, the device can
be connected with a SICAM I/O Unit. This device combination can be connected with the process control via
the second connector of the Y cable and an external Ethernet switch.
