- Description
The Siemens 6BK1700-0BA20-0AA0 is a LOGO! CMK2000 communication module that integrates the LOGO! 8 logic module into a KNX building-system bus. It mounts on a 35 mm DIN rail, connects at 24 V DC drawing 0.04 A, adds one RJ45 Ethernet port, supports 50 communication objects, and provides time-of-day synchronization with web-based configuration and diagnostics through its built-in web server.

Selection Notes
The CMK2000 is the LOGO! 8 gateway onto KNX/EIB building-bus systems; choose it when a LOGO! program needs to publish or receive up to 50 KNX communication objects on the same panel that already runs standard LOGO! Ethernet communication. The single RJ45 port carries LOGO! communication on the PLC side while the KNX terminal handles the field-bus side, so no separate gateway device is required.
