The Logo! CMK2000 communication module from Siemens, the current 'Logo! 8' logic module series can be integrated into the KNX building system bus and thus used for building automation tasks such as monitoring, access control, air conditioning, lighting, shading and irrigation through to pump control. The KNX module communicates with the logic module via Ethernet. It forwards sensor data from KNX bus devices to the logic module, where it is combined with logic functions. Logo! control commands are forwarded to KNX actuators via the communication module. 50 KNX communication objects can be configured and linked in the Logo! program with counters, setpoints and parameters to create automation solutions. The logic module also provides the other KNX participants with its own functionality via the communication module - in the full hardware configuration, this includes 24 digital inputs and 20 digital outputs as well as eight analog inputs and eight analog outputs. It is also possible to synchronize the date and time for the participants in the KNX system.
