2 1. Functional description The application program 07 B0 CO IP Gateway KNX-BACnet can be used for the KNX device listed above. This device 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 BACnet communication. The Gateway provides up to 250 communication objects. Via these objects KNX functions (group addresses) are transposed 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. The following 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 the following process: The BACnet object instance number is identical to the object number of the ETS. Objects with a 1 bit data type are translated 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 BACnet objects. 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 resource optimization is based on the fact that subscriptions are required for objects which send from KNX to BACnet whilst priority arrays 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 decreases accordingly. The maximum possible number of subscriptions is displayed on the device website once the configuration is complete. When a subscription is registered the BACnet object sends its current value, if a value is available for this object. The validity of a value can be verified via the status property (Failure flag). Initially, the status failure flag for the object types Binary Input, Binary Value, Analog Input and Analog Value is set to TRUE. Once a value is transmitted from the KNX bus or from BACnet (for Binary Value or Analog Value) this status flag is set to FALSE.

3 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 this property is set to TRUE, the communication of the respective object with KNX is inhibited. Values of Input objects can then be 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 especially important for finding errors in complex systems. When the description of an object is requested from the BACnet side (ReadProperty Description ), the description text is automatically generated and assembled from the object name, BACnet identifier and KNX group address data separated by a colon ( : ). The device is equipped with a web server presenting the configuration and current values in an overview page. This presentation 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 P. O. Box , D Regensburg Subject to change without further notice 3/39

4 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 between UTF-8 and ISO 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 settings in ETS4 / ETS5. The encoding is set in ETS4 / ETS5 for the project under General - Codepage. The UTF-8 character set should be selected. When ETS3 is used for configuration then special characters inserted with ETS3 are encoded with the ISO character 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 device itself as well as other KNX devices of the attached KNX line. Behavior at bus voltage failure / recovery Failure 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 state In the default factory state the device has no Gateway function. The IP address is preset to Behavior on unloading the application program When 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 settings The device cannot be reset to the factory default settings.

6 3. Functions (Objects, s) For the functions of the IP Gateway KNX/BACnet first general configuration settings and then the configuration of the 250 Objects have to be done. Note The number and names of the parameter windows in the ETS menus may vary as they are controlled via parameter settings. Another parameter window may appear if due to dynamically added parameters the space in the first parameter window is exhausted. General settings General settings This parameter window is used to set - a device name for identification of the device via KNXnet/IP, - the type of IP address assignment, - the start and cycle time for Read Requests from status objects, and - the base parameters for communication via BAcnet. Device name N143_IP_Gateway_BACnet_KNX (max. 30 char) This parameter assigns a name with up to 30 characters to the IP Gateway KNX/BACnet N 143. This name is used for easy recognition of the device when searched by a KNXnet/IP visualization or the ETS. IP address assignment manual input by DHCP Server This parameter determines the type of IP address assignment. By default DHCP is preset for automatic address assignment by a DHCP server. When manual input is selected, an additional tab for manual input of IP address, subnet mask and the default gateway appears.

7 Start delay for ReadOnInit 10 seconds 20 seconds 30 seconds 1 minute 2 minutes 3 minutes 4 minutes 5 minutes This parameter determines the time delay after bus voltage recovery before read requests of status objects are started. Delay between ReadRequests 100 milliseconds 200 milliseconds 500 milliseconds 1 second 2 seconds This parameter determines the time delay between Read Requests of the individual status objects. Device Instance (must be unique) This parameter defines the unique device ID. The ID is an integer value. Value range ( ) BACnet communication port Use this parameter to change the port number of the BACnet server. The pre-set port is DCC Password This parameter defines the password to control the device on the BACnet side (up to 8 characters). By using the BACnet Service DeviceCommunicationControl the device can be temporarily muted for diagnostic purposes. This means all BACnet services apart from DCC are de-activated in order to re-set the device to its normal status. BACnet communication timeout 100 ms 200 ms ms 1 s This parameter determines the time to wait for the BACnet acknowledgement. BACnet communication retries 1 retry 2 retries 3 retries Use this parameter to determine how many times you would like to repeat a request in case of wrong acknowledgement. P. O.

8 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. 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 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 priority levels for each priority supporting BACnet object. The output value of the highest priority (this is the lowest priority number) 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 possible memory space for COV subscriptions no yes Update: DS02 Siemens AG Siemens AG 2017 Control Products and Systems 8/39 Subject to change without further notice P.

Additionally, the data transposition from KNX to BACnet and vice versa is determined by this parameter. Note: KNX 32-bit integer values are transposed on BACnet to analog values, i.e. they are transmitted on BACnet as floating point values. Hence, integer values larger than are transposed with a rounding error into a BACnet analog value. A rounding error also occurs in the opposite transmission direction from BACNet to KNX values larger than Update: DS02 Siemens AG Siemens AG 2017 Control Products and Systems 28/39 Subject to change without further notice P.
