Advice on NXB-KNX IP communication

Hi guys,

So I have a NXB-KNX on system 1(server) and I want system 2 (client) to be able to communicate with system 1 by sending a button_event to open up a light.

How can I do that?

Regards all!

    Add a URL list on one of the masters to point to the other system, then talk directly to the KNX from system 2.

    On the other hand, its not possible.
    You see, NXB-KNX is communicating via IP.
    What I have is this setup:
    System 1:
    1xNXB-KNX connected to the System 1 master
    1xTouchPanel can control light 1 on KNX system

    System 2:
    1xSystem 2 master
    1xTouchPanel should be able to turn on Light 2 on the KNX System.


    How would the IP communication be setup?
    I did the following:
    System 1:
    DEFINE_CONSTANT
    system1 = 0:3:0
    port = 8000
    DEFINE_START
    IP_SERVER_OPEN (system1.port, port, IP_TCP)


    System 2:
    DEFINE_DEVICE
    dvNXB = 13001:1:1 // on system 1
    dvTP2 = 10001:1:2 //on system 2
    DEFINE_CONSTANT
    system2 = 0:4:0
    serverip[] = {192.168.40.55}
    port = 8000
    DEFINE_START
    IP_CLIENT_OPEN (system2.port, serverip, port, IP_TCP)

    button_event[dvTP2, 1]
    {
    push:
    {
    switch(button.input.channel)
    {
    case 1: { KNXSet(dvNXB, 3, 1) }
    case 2: { KNXSet(dvNXB, 3, 0) }
    }
    }
    }


    but the problem is that its not even working.

    With Master-to-Master communication, you don't need to set up any sockets manually. Once you have the URL List properly configured, there is constant communication between the two. Using D:P:S, you have direct access to any of the other system's devices.

    System 1: 
    DEFINE_DEVICE
  dvNXB = 13001:1:1
  dvTP1 = 10001:1:1

    System 2: 
    DEFINE_DEVICE
  dvNXB_on_System_1 = 13001:1:1  // you can name it 'dvNXB' just added the extra for clarity
  dvTP2 = 10001:1:2

DEFINE_EVENT
  BUTTON_EVENT [dvTP2,1] {
    PUSH : {
      SEND_COMMAND dvNXB_on_System_1,"'*** Insert Command Here ***'"
    }
  }

    That's all you have to do. The dvNXB device definition within System 2 is pointing to System 1. Therefore, you can send commands, channels, etc. Just as you would from System 1.
