Is it possible to bind several objects that send a pre set scene (DPT4.002 1byte char) to one group address that is bound to a Wago KNX/IP module (750-830) and let the WAGO read scenevalues? Lets say I have 3 scene objects and binding them to 0/0/1. Then the PLC evalutes the value it gets and does the next step. Thus removing the need for xx group addresses sending each their own scenevalue (1byte) and binding them to the same Wago module. |

Wago KNX/IP controller is 750-849. Answering the question - If I undestood you correctly, you want to interpretate the value scene (DPT_SceneControl or DPT_Value_1_Ucount, not DPT4 char) and send some sequence of telegrams to different group addresses? F.E. if the value of scene (0/0/1) is 1, than send sequence of telegrams with value "1" to 0/0/2, value "0" to 0/0/3. If the value of scene (0/0/1) is 2, than send sequence of telegrams with value "0" to 0/0/2 and value "1" to 0/0/4 (!not 0/0/3) The answer is: YES, it is possible, but not very easy to implement :-) |

Great answer :) After some fiddling with this on the evenings away from work just to see if it is a better way it worked like a charm! Using mainly Ucount blocks it works on all DPT types and it opened up for some funny mods using various components. Saved me a couple of group adresses in ETS too so can extend the WAGO modules inherent limit of communication, but I dont know if the cost of a new extra device is lower than the cost of building/extending the addresses like this. |
