Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
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.
Qualified Personnel
The product/system described in this documentation may be operated only by

Safety extra-low voltage
Note
Only connect the device via a safety extra-low voltage
The device is designed for operation using directly connectable safety extra
-low voltage
(SELV) with safe electrical isolation according to IEC 60950
-1 / EN 60950-1 / VDE 0805-1.
The following applies to use in North America: The power supply unit for sup
plying the
device with power must comply with NEC Class 2 in accordance with National Electrical
Code (ANSI / NFPA 70).
You must, therefore, only connect the supply terminals and the process and communication
signals (including Ethernet) to safety extra
-low voltages (SELV) with safe electrical isolation
to IEC 60950
-1 / EN 60950-1 / VDE 0805-1.
Note
Safety extra-low voltage
Contact with live components can result in a mild electric shock.
•
Disconnect from the power supply before starting work.
•
Ensure that no wires or strands protrude from the terminals that can be touched.
Working on the device or on connected components
WARNING
Risk of electric shock
May cause death or serious injury
•Voltages > 60 V are present in the control cabinet. Therefore appropriate safety
precautions must be taken to prevent contact during commissioning and maintenance
work.
•Before carrying out any work on the device or on connected components, make sure
that the installation is in a zero-voltage state.
•UL-approved cable types must be used for UL-certified systems (60/75°C).

IT security
IT security guidelines
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, solutions, machines, equipment and/or networks. They are
important components in a holistic industrial security concept. With this in mind, Siemens’
products and solutions undergo continuous development. Siemens recommends strongly
that you regularly check for product updates.
For the secure operation of Siemens products and solutions, it is necessary to take suitable
preventive action (e.g. cell protection concept) and integrate each component into a holistic,
state-of-the-art industrial security concept. Third-party products that may be in use should
also be considered. For more information about industrial security, visit
http://www.siemens.com/industrialsecurity.
To stay informed about product updates as they occur, sign up for a product-specific
newsletter. For more information, visit http://support.automation.siemens.com.
Protective measures for CMK2000
NOTICE
Only authorized personnel are permitted to access the system and carry out modifications.

3.1
Field of application
Image 3-1 LOGO! 8 and CMK2000
The CMK2000 is a communication module from the LOGO! series with KNX interface.
The LOGO! 8 can be integrated into the KNX system using the CMK2000. It is then possible
to exchange information and data between LOGO! 8 and KNX. The LOGO! 8 is then a
universal and flexible control unit in the KNX network.
The combination between LOGO! 8 and CMK2000 allows:
●Logic combination of the signals from KNX devices
●Evaluation of KNX values in the LOGO!
●Control of KNX actuators from the LOGO! Soft Comfort series
●Use of inexpensive actuators and sensors in the KNX environment
●Simple expansion of KNX functions without ETS knowledge

Features
●CMK2000 together with LOGO! allows the use of inexpensive actuators and sensors in
the KNX environment
●KNX devices can access the signal states of all inputs and outputs of the LOGO! 8.
●Standard LOGO! functions can be used, e.g.: logic functions, ON/OFF delays.
●Various KNX data point types can be made available by CMK2000 and LOGO!.
●Various LOGO! variable types can be sent to KNX devices, e.g. LOGO! analog values as
settings for KNX devices as float values.
●Time synchronization between KNX and LOGO! is possible.
●No inputs or outputs are occupied in the process image of the LOGO! 8 for the KNX
communication (saving is possible in the variable memory).
Note
Not more than one CMK2000 KNX device may be connected to a LOGO!.

communication module between LOGO! and KNX.
Image 3-2 CMK2000 configuration example
Tasks and meanings of the system components
The CMK2000 communication module allows the transfer and system-compatible scaling of
data between KNX and LOGO!.
Depending on the parameter assignment in the ETS, the data flow is either from LOGO! to
KNX or vice versa from KNX to LOGO!.
The CMK2000 is connected over Ethernet to the LOGO! 8. The power supply to the
CMK2000 is made using an external power unit with 24 V DC.
The bus cable between CMK2000 and the KNX system is implemented as a two-wire
connection (twisted pair). The bus cable provides the KNX nodes with data and also the
operating voltage of 29 V DC from the KNX power supply.
Configuration / parameter assignment / commissioning of the CMK2000 is carried out using
a personal computer with the ETS (Engineering Tool Software) via a KNX interface such as
USB or IP interface.
