1. Functional descriptionThe application program “07 B0 CO IP Gateway KNX-BACnet 983602” can be used for the KNX device listed above. Thisdevice is briefly described in the next section.

The IP Gateway KNX/BACnet N 143 is a DIN rail mounted device connecting a KNX installation with a system using BACnetcommunication.The Gateway provides up to 250 communication objects. Via these objects KNX functions (group addresses) are trans-posed to BACnet objects.

The communication objects can be configured optionally as:∂ switching/status on/off (1 bit)∂ 8-bit value (percent value)∂ 8-bit value (unsigned integer)∂ 8-bit value (signed integer)∂ 16-bit value (unsigned integer)∂ 16-bit value (signed integer)∂ 16-bit value (float)∂ 32-bit value (unsigned integer)∂ 32-bit value (signed integer)∂ 32-bit value (float)

The device is configured entirely with ETS.

The configuration of the KNX communication objects automatically generates the corresponding BACnet objects. Thefollowing BACnet objects are being used:

∂ Binary Input∂ Binary Output∂ Binary Value∂ Analog Input∂ Analog Output∂ Analog Value

No special knowledge about BACnet is required for the commissioning.The KNX objects configured with ETS are automatically “translated” by the device into BACnet objects according to thefollowing process:The BACnet object instance number is identical to the object number of the ETS. Objects with a 1 bit data type are trans-lated into “binary” objects. All others become “analog” objects. The parameter “Object Mode” (INPUT, OUTPUT, VALUE)completes the transformation to a BACnet object.

On BACnet the IP Gateway KNX/BACnet N 143 appears as an Application Specific Controller (B-ASC) with up to 250 BACnetobjects. BACnet clients may set up to 455 BACnet change-of-value (COV) subscriptions for these 250 BACnet objects.A common memory space is available for the administration of the COV subscriptions and priority arrays. This resourceoptimization is based on the fact that subscriptions are required for objects which send from KNX to BACnet whilst priorityarrays are for objects sending from BACnet to KNX.The maximum number of possible subscriptions is 455 if no priority arrays are used.As each priority array has a size of 64 Byte (16 priority levels of 4 Byte each), the number of possible subscriptions de-creases accordingly. The maximum possible number of subscriptions is displayed on the device website once the configu-ration is complete.

When a subscription is registered the BACnet object sends its current value, if a value is available for this object. Thevalidity of a value can be verified via the status property (Failure flag). Initially, the status failure flag for the object typesBinary Input, Binary Value, Analog Input and Analog Value is set to TRUE. Once a value is transmitted from the KNX bus orfrom BACnet (for Binary Value or Analog Value) this status flag is set to FALSE.

GAMMA instabus


July 2017



When using a Priority Array with all Priority Array positions released then the last received KNX value is sent as“relinquish default”, if the value is valid.

All Analog and Binary BACnet objects supported by the device support the writeable Out-Of-Service property. When thisproperty is set to TRUE, the communication of the respective object with KNX is inhibited. Values of Input objects can thenbe changed from the BACnet side, which otherwise would not be possible. Value changes of objects with set Out-Of-Service property are also indicated via the object status flag Overridden. The Out-Of-Service flag handling is especiallyimportant for finding errors in complex systems.

When the description of an object is requested from the BACnet side (ReadProperty “Description”), the description text isautomatically generated and assembled from the object name, BACnet identifier and KNX group address data separatedby a colon (“:”).

The device is equipped with a web server presenting the configuration and current values in an overview page. Thispresentation is helpful for testing purposes and for documentation of the interface between KNX and BACnet.The web page contains a header section showing general device specific information:

∂ Device name∂ Device description∂ Installation location∂ Device status∂ BACnet instance number of the device∂ Firmware version∂ Revision number∂ Physical KNX address∂ IP address∂ Netmask∂ Gateway address∂ MAC address∂ Number of configured objects∂ Maximum number of possible COV subscriptions∂ Current number of COV subscriptions∂ Priority: This displays the priority array, which is used to transmit events from KNX to BACnet∂ Number of binary input objects∂ Number of binary output objects∂ Number of binary value objects∂ Number of analog input objects∂ Number of analog output objects∂ Number of analog value objects

Beneath the header is a table listing all configured objects. The table is divided into the following columns:∂ Object number∂ Object name

GAMMA instabus


July 2017




∂ BACnet object ID∂ KNX group address∂ Data type∂ Transmission mode∂ Reading during initialisation∂ Unit∂ Object value

Object values are not dynamically up-dated on the website. To up-date the objects, please re-load the website.

An EDE (Engineering Data Exchange) list can be exported via the button „Export EDE“ on the right side of the web page.

Note

In general, the webpage is coded for the UTF-8 character set. A selection field on the web page allows switching betweenUTF-8 and ISO 8859-1 encoding. Thus the presentation can be adapted to the encoding downloaded by ETS.When ETS4 / ETS5 is used for configuration then texts (including special characters) are coded dependent on the settingsin ETS4 / ETS5. The encoding is set in ETS4 / ETS5 for the project under General - Codepage. The UTF-8 character setshould be selected.When ETS3 is used for configuration then special characters inserted with ETS3 are encoded with the ISO 8859-1 charac-ter set.Texts to be communicated via BACnet are transmitted as entered in ETS.

Besides the function as IP Gateway KNX-BACnet the device also provides an IP Interface for ETS configuration of the deviceitself as well as other KNX devices of the attached KNX line.

Behavior at bus voltage failure / recoveryFailure of the auxiliary power (DC 24V) results in a functional failure of the device.A bus voltage failure results in a functional failure of the device.On bus voltage recovery the configured actions are executed and, if applicable, new status values are reported.The device sends “I am” onto BACnet.

Factory default stateIn the default factory state the device has no Gateway function.The IP address is preset to 192.168.1.135.

Behavior on unloading the application programWhen the application program is unloaded with ETS the device does not function.All BACnet objects are still visible but are set to “out of service”.The property “data base revision” in the BACnet Device is incremented by one.The web server stays in operation.

Resetting the device to factory default settingsThe device cannot be reset to the factory default settings.

Parameter „Optional settings“

This parameter window is used- to store the installation location as information in the device,- to store a brief description of the device as information in the device itself,- to determine the use of priority arrays, and- to register as foreign device at BBMD.

Parameter Settings

Device Location

This parameter can be used to enter an installation location of the device for easier localization in the building.Up to 30 characters can be used.

Device Description

This parameter can be used to enter a brief device description for the device. Up to 30 characters can be used.

Usage of priority arrays noyes

This parameter generally determines if priority arrays are available for use.

The BACnet standard assumes the usage of priority arrays for the BACnet object types Binary Output, Binary Value,Analog Output and Analog Value supported by the device. According to the standard the device supports 16 prioritylevels for each priority supporting BACnet object. The output value of the highest priority (this is the lowest prioritynumber) is active. All other values with lower priority are stored (one value per priority level and object).

In most cases this functionality is not required. By default priority arrays are disabled to have the highest possiblememory space for COV subscriptions
