This application example offers you a complete time switch function for LOGO! 8 and shows you how to mount it into a KNX system via the CMK2000.



Advantages
The combination of the time switch function in LOGO! 8 and the CMK2000 module
offers you the following advantages:

  • Switching of actuators at configurable times
  • Configuration of timer via the LOGO! display
  • Configuration of timer using the integrated Web server of the LOGO! 8
  • Integration of LOGO! inputs and output into a KNX system

Target group
This application example is aimed at experienced KNX users who seek to expand
their KNX system with the functionalities of a LOGO! 8.

Security Notes 
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.
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.
