symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Security information
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
http://www.siemens.com/industrialsecurity (http://www.siemens.com/industrialsecurity)
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.

Appearance
The following figure shows the CP 1626 communications processor.
Properties
The CP 1626 is a PCIe module for connecting PGs/PCs to Industrial Ethernet. The essential
properties are as follows:
●Optimized for PROFINET IO
●With Ethernet real-time ASIC SOC-1 and ERTEC 200 P
●Four RJ-45 jacks for connection of end devices or other network components
●2 integrated 2-port real-time switches
●Automatic hardware detection is supported

Description of the device
CP 1626
12 Operating Instructions, 11/2018, C79000-G8976-C434-03
●Operation of IO device and IO controller at the same time
●Network separation (different IP subnets for IO device and IO controller operation)
Hardware requirement
To be able to operate, the CP 1626 requires a short PCIe slot with master capability.

–
Communications connection is established.
on – Link status error has occurred.
flashing slowly – There are two possible causes:
•An IO device cannot be addressed.
•An IP address was assigned twice.
–
off
No fault/error.
–
on
Diagnostics information is available.
Alternating slow flashing and flashing of
the 2 port LEDs (yellow and green) of the
X1 interface
Flash test for recognizing the communications processor.
Alternating fast flashing A disruption has occurred.
In this case, diagnostics via the Web or using SNMP is
no longer possible.
Note
If this error occurs, contact Technical Support. You will
find the contact data in the section "Preface (Page 3)".
External power supply
The CP 1626 has a socket for connecting an external power supply.
With this power supply, the integrated real-time switches of the X1 and X2 interfaces can
operate even if the PC is turned off.
It also allows the host PC to be turned on again after being switched off by PROFIenergy.
Ethernet
The CP 1626 is intended for operation in Ethernet networks.
It also has the following features:
●The connectors are designed for 100BaseTX.
●Data transmission speed of 100 Mbps in full/half duplex is supported.
●Autonegotiation (can also be turned off)
●Autocrossing

Description of the device
CP 1626
14 Operating Instructions, 11/2018, C79000-G8976-C434-03
RJ-45 jacks
The connection of the communications processor 1626 to the LAN (local area network) is via
one of the four RJ-45 jacks on the front panel of the communications processor.
In each case, 2 jacks are connected to the integrated real-time switch.
Jacks 1 and 2 are intended for IO device operation.
Jacks 3 and 4 allow IO controller and/or IO device operation.
Note
For the "network separation" property, use sockets 1
and 2 for one IP subnet and sockets 3
and 4 for the other IP subnet.
CP 1626 in a PC as IO controller
The following figure shows a typical application:
PC with CP 1626 as PROFINET IO controller at the IO controller level.
The IO-Base controller user program runs on the PC and accesses the functions of the IO-
Base user programming interface.
The data traffic is handled via a CP 1626 with several SIMATIC S7 PROFINET IO devices
ET 200S via Industrial Ethernet.

Operating Instructions, 11/2018, C79000-G8976-C434-03 15
CP 1626 in a PC as IO device
The following figure shows a typical application:
Two PCs each with a CP 1626 as PROFINET IO device at the IO device level.
There are also a PC with a CP 1626 as PROFINET IO controller, a SIMATIC S7-400 with a
CP 443-1 as PROFINET IO controller and two SIMATIC S7 ET 200S PROFINET IO devices
connected in the network.
On the IO device PCs, there is an IO-Base device user program running that accesses the
functions of the IO-Base user programming interface. The data traffic is handled via a CP
1626 to a PC as PROFINET IO controller or an S7-400 automation system with a CP 443-1
via Industrial Ethernet.

CP 1626 in a PC with network separation
The following figure shows the CP 1626 being used in "network separation". To do this the
communications processor is connected to an automation system S7-400 with a CP 443-1
Advanced as PROFINET IO controller via the X2 interface with IP subnet 1.
Via the X1 interface of the CP 443-1 Advanced and IP subnet 2 the CP 1626 is connected to
the SIMATIC S7 ET 200S PROFINET IO devices. This makes it possible to keep disruptive
influences occurring in IP subnet 1 away from IP subnet 2 and there are more IP addresses
available.

2.1
Important information
Electrostatic sensitive components
Keep to the measures for preventing electrostatic charges when installing the
communications processor.
(ESD - electrostatic sensitive devices)
Installing the CP 1626
Opening the PC and plugging or pulling the submodules is permitted only when the power is
off.
Read the manual
Before installing the communications processor, read the section "Procedure for installing
PCIe modules" or similar in the manual of your PC and keep to the instructions.
External power supply
The CP 1626 has a socket for connecting an external power supply.
With this power supply (12 to 24 VDC), the CP 1626 can operate as a switch even if the PC
is turned off.

Hardware installation
2.1 Important information
CP 1626
18 Operating Instructions, 11/2018, C79000-G8976-C434-03
Use of a holding plate
When being used in environments with increased mechanical stress, installation with the
holding plate supplied with the product is recommended (see following graphic). This
improves the mechanical stability of the plug-in connection. You secure the outgoing cables
to the holding plate with cable ties.
Passive network components
You will find important notes on the use of passive network components in the document
"Industrial Ethernet / PROFINET Passive Network Components"
(https://support.industry.siemens.com/cs/ww/en/view/84922825).
