7.2.1
Ethernet Interface
The Ethernet interface Z is located on the top side of the SICAM Q100. Data are exchanged via the
RJ45 Ethernet socket, see also detailed information in System Manual SICAM Q100 7KG95xx, order number
E50417-C1040-C482, chapter 2.

NOTE
If you do not connect a cable to the RJ45 socket, Siemens recommends to cover the socket with a cap or dum-
my plug (not included in the delivery) to prevent the contacts from becoming dirty.
If you use a Y cable and the internal Ethernet switch of the device, SICAM Q100 can be connected with a SI-
CAM 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. For typical circuit diagrams, refer to the System Manual
SICAM Q100 7KG95xx, order no. E50417-C1000-C522, chapter 2.
7.2.2
RS485 Interface
The RS485 interface J (D-Sub) is located on the terminal side; see also detailed information in the System Man-
ual SICAM Q100 7KG95xx, order no. E50417-C1000-C522, chapter 2.
