Logo will only serve to control the lighting of the building. THe problem is, I would like to cut all the building's lighting when a part of it is connected to the first logo and the other part to the second logo. How could I do?

Theoretically there are lots of ways to make it very complicated. You are right one complicated way is to exchange data between the LOGO! (if it would be possible) You can exchange data between several LOGO!'s via EIB/KNX bus. This sollution requires a EIB/KNX EM at each LOGO!. The simplest way is to wire the sensor (to switch off all lights) to the inputs of both LOGO!'s and switch off the outputs in the LOGO! program. Hope this helps

Andres [Str] Posts: 153 Rating: (16)	The example of communication of two modules with EIB/KNX is here http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=21688364&caller=view Darkduino can tell about the problem in more details. LOGO there is a universal device and solve a problem can to be it will be easier. I consider use LOGO in networks EIB as more successful when already there is a network EIB

darkduino Posts: 4 Rating: (0)	So everything is already wired in the logo. Input, they are buttons. Output lamps, at least for the moment. Simply, it is a logo with 20 entries and another with 16 entries. For now, I've programmed the first logo. It cuts the light output which is the first logo. I want that pressing this button (which enters the first logo), lighting the entire building (including so what is the output on the second LOGO) In the diagram you sent me, I have the modules 1 and 2, I'll have to buy the module is 3 but I have to buy 4 as to connect the 2 LOGO? http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=21688364&caller=view Thank you

Andres [Str] Posts: 153 Rating: (16)	Hi darkduino You use more devices, ability to work with 2 programs (LOGO!SOFT and ETS) and to understand bus structure.Very perspective direction for building automation and this technology more than 20 years. Attachment 2 Logos via KNX.JPG (543 Downloads)
