      This section provides settings and information in order to configure the connection between a computer and a KNX installation. There are 3 subsections here, which are the following:

      Current Interface

      Shows the currently active bus connection. The Settings in the right-hand window can be used to set the local Individual Address of this connection.

      Configured Interfaces

      List of all configured connections (regardless of their current availability). The following buttons are available:

      Button Description
      add_16.png Creates a new connection
      delete_16.png Deletes one single selected connection
      import_data_16.png Imports configured interfaces (see here)
      export_data_16.png Exports configured interfaces (see here)

      The list may contain the following information:

      Icon  Connection type Name/IP Address

      connectionUsb.png

      USB

      Shows the user-defined Name and if the connection type is IP, the assigned IP address (as well as MAC address, address will be accepted when the connection is established/configured).

      The user- defined Name on KNXnet/IP tunneling (devices) is downloaded into the device later on. The length limitation in the device itself is 30 chars (fixed by the KNX Specifications). When the device/interface is "discovered" later by ETS the Name out of the device with maximal 30 chars is shown.

      KNXnet/IP area line detected

      security_16.png

      KNX IP Secure secured area line detected

      • The communication on the area line is secured (which is not the same thing as having devices on the area line which could use secured communication).
      • The interface is here on the Bus tab and is not selectable without a project reference (correct key from projects not assignable)
      • The interface can only be selected and used when there is a project reference (then with an available and suitable security key).

      A red dot (InProgMode.png) right after the icon above indicates that the interface is in Programming Mode (refreshes every ~3 seconds).

      Properties

      The properties are shown in the right-hand window. For the current interface, next to the 'Individual Address' field there is a button to test whether the given Individual Address is free.

      Property Description
      Name User friendly name for the connection (for KNXnet/IP connections, its is shown as 'user friendly name', the name - from device properties/sidebar of interface from the ETS project)

      The following information is displayed depending on the interface type that has been selected.

      Parameter modification is only possible if the interface has been manually created.

      KNXnet/IP tunneling

      Property Description
      Name Name of the interface
      Server Desired IP address of the interface (if interface is self-defined) or name, server for resolution of an IP address (text input)
      IP address IP address found for the interface
      Port 3671 (default)
      Host Individual Address Individual Address of the host device
      Individual Address Further available Individual Addresses of the host device; for details, see
      Network Address Translation

      Enables/Disables Network Address Translation.

      NAT is only necessary when creating an interface if it cannot be automatically found. If an interface is found by ETS automatically, the NAT option does no longer needs to be set explicitly.

      KNXnet/IP routing

      Property Description
      Name Name of the interface
      Individual Address

      Individual Address of the (local) interface; preselection for the area line (0.0.1)
      Port 3671 (default); always permanent for routing and consequently, cannot be changed.
      Routing Multicast Address

      224.0.23.12 (default)

      • The Routing Multicast Address can be identical to the default address above, but it does not have to be (e.g. for several separate KNX installations on IP/ a LAN).
      • The default address above is also the standardized Multicast Address that is always used in KNX for device search (system setup Multicast Address); it should also be supported as such by all devices.
      MAC Address MAC Hardware address of the interface.

      EIBlib/IP

      Property Description
      Name Name of the interface
      Server

      IP address of the interface
      Protocol

      TCP or UDP
      Port Configuration/read/write port (5000x)
      COM COM connection number

      USB

      Property Description
      Name Name of the interface
      Manufacturer Manufacturer of the interface
      Medium Medium to which the USB interface is connected to
      Individual Address The interface's Individual Address, as well as a button to test whether the given Individual Address is free.
      APDU length The maximum data length within a telegram that the interface can handle.

       

      Discovered Interfaces

      Here you will see a list of all existing connections unless they are already in the Configured Connections list.

      USB and IP routing interfaces are recognized and displayed automatically by ETS5, they do not need to be created. A not recognized interface cannot be used by ETS even if it is manually created.
