Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit

The CP 1623 is a PCIe module for connecting PGs/PCs to Industrial Ethernet. The essential
properties are as follows:
● Two RJ-45 ports for Industrial Ethernet for connecting twisted-pair cables
● Can be used as a 2-port switch (both RJ-45 connectors lead to the integrated switch)
● The following data rates are supported:
– 10/100 Mbps (half/full duplex)
– 1000 Mbps (full duplex)
● Own processor on the CP 1623 relieves the PC/PG CPU
● Autosensing, autocrossover, autonegotiation
● ISO and TCP/IP transport protocol onboard
The CP 1623 requires a PCIe slot (PCI express x1; can also be operated in x4, x8 or x16
slots).
