What does that mean? as 50 communication devices? like for example 50 KNX thermostats to one Logo 8 ? and how many KNX modules can I have with one logo 8? Thank you

Each of this 50 data you can forward to several other KNX devices. Or in the oposit way LOGO! can receive 50 data from KNX devices. The manual stated only one CMK2000 at one LOGO!. Hope this helps

Thank you for your patience :) Helmut_13 Hi, do you know KNX? You can communicate for example 50 digital or analogue information from/to LOGO! via the CMK2000.

Helmut_13 Posts: 2930 Rating: (432)	Hi, NO, you are wrong. KNX is completely different. Examle: In LOGO! you have an digital signal (flag) used as an alarm. This is in the LOGO! KNX module ONE datapoint. In the KNX side this siganl can be used at any connected device to show the Alarm. Better for you to understand KNX is to visit an KNX workshop to get experiances. Especially aboute the differences between factory automation and KNX. There are some very important differences you need to know. Otherwise it will be very hard for you to use the LOGO! CMK2000. Hope this helps
