This device is briefly described in the next section. The IP Gateway KN/BACnet N 143 is a DIN rail mounted device connecting a KN installation with a system using BACnet communication. The Gateway provides up to 250 communication objects. Via these objects KN 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 KN communication objects automatically generates the corresponding BACnet objects. The following BACnet objects are being used: Binary Binary Binary Analog Analog Analog No special knowledge about BACnet is required for the commissioning. The KN 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. 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 KN/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 Siemens AG , page 1 / 20 Technical manual Infrastructure and Cities Sector, Building Technologies Control Products and Systems Siemens AG 2014 Update: P. O.

2 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 KN to BACnet whilst priority arrays are for objects sending from BACnet to KN. 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, Binary, Analog and Analog is set to TRUE. Once a value is transmitted from the KN bus or from BACnet (for Binary or Analog ) this status flag is set to FALSE. 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 KN is inhibited. s of objects can then be changed from the BACnet side, which otherwise would not be possible. changes of objects with set Out-Of-Service property are also indicatedvia 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 KN 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 KN and BACnet. The web page contains a header section showing general device specific information: Device name BACnet instance number of the device MAC address IP address Netmask Gateway address Physical KN address Number of configured objects Maximum number of possible COV subscriptions 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 BACnet object ID KN 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. Besides the function as IP Gateway KN-BACnet the device also provides an IP Interface for ETS configuration of the device itself as well as other KN devices of the attached KN 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 devices 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 Technical manual , page 2 / 20 Siemens AG Update: Siemens AG 2014 Control Products and Systems Subject to change without further notice P. O. Box , D Regensburg /2

3 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 sevice. 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. 2. Communication objects Maximum number of group addresses: 255 Maximum number of assignments: 511 Note The number and names of communication objects visible can vary depending on the parameter settings. The application program already has been loaded in the factory. The device is configured and commissioned with the ETS (Engineering Tool Software) version ETS3 v3.0f or later. With the ETS (Engineering Tool Software) the specific parameters and addresses are assigned appropriately, and downloaded into the device. The following list shows all objects of the device. Which objects are visible and linkable to group addresses is defined via the functions assigned to the inputs. The objects and associated parameter settings are described with the functions.

4 3. Functions (, s) For the functions of the IP Gateway KN/BACnet first general configuration settings and then the configuration of the 250 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 This parameter window is used to set - a device name for identification of the device via KNnet/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 IP_Gateway_KN_BACnet_N143 (max. 30 char) (don t use blanks) This parameter assigns a name with up to 30 characters to the IP Gateway KN/BACnet N 143. This name is used for easy recognition of the device when searched ny a KNnet/IP visualization or the ETS. IP address assigment 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, two additional tabs for manual input of IP address, subnet mask and the default gateway appear. Start delay for Read on Init 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 Read Requests 100 ms 200 ms 500 ms 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. 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.

5 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. IP Optional 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, and - to determine the use of priority arrays. Device location This parameter can be used to enter an installation location of the device for easier localization in the building. Device description This parameter can be used to enter a breif device description for the device. Up to 30 characters can be used. Usage of priority arrays no 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, Binary, Analog and Analog 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 This parameter window is visible when the parameter IP address assignment has been set to manual input. IP address byte 1, byte 2, byte 3, byte 4 This parameter determines the IP address if the IP settings are manually assigned. The factory default value for the IP address is This preset value must be replaced with a valid IP address for the target network. The four bytes of the IP address must be entered individually. The value range for each byte is Subnet mask byte 1, byte 2, byte 3, byte 4 This parameter determines the IP subnet mask if the IP settings are manually assigned. The factory default value for the IP subnet mask is This preset value must be replaced with a valid IP subnet mask for the target network. Valid subnet mask may be e.g or The four bytes of the IP subnet mask must be entered individually. The value range for each byte is Siemens AG , page 5 / 20 Technical manual Control Products and Systems Siemens AG 2014 Update: P. O. Box , D Regensburg Subject to change without further notice /5

6 Gateway address byte 1, byte 2, byte 3, byte 4 This parameter determines the standard gateway address if the IP settings are manually assigned.
