BACNET MA NUAL1GeneralM4M network analyzers offer includes versions with BACnet communication protocol (M4M 20 BACnet and M4M 30 BACnet)1.1BACnetBACnet is data communication protocol for Building Automation and Control networks designed for building automation networks. It is defined by ANSI/ASHRAE135 standard document. The protocol defines standard for data exchange between devices present in building automation networks, including HVAC, lightingcontrol, access control. BACnet is object-oriented, client-server protocol.ANSI/ASHRAE-135 defines list of standard object types and services that allowaccessing, modification and interactions with objects as well as discovering thenetwork devices and their capabilities. Also data-link/physical layers are definedby the standard.ANSI/ASHRAE-135 defines series of standard device profiles. M4M BACnet implements BACnet Application specific profile (B-ASC). This profile defines the deviceas controller with limited resources that supports limited programmability and isable to provide complete information about any of its BACnet objects and canrespond to communication control messages.1.1.1BACnet/IP data link layerM4M BACnet implements BACnet/IP data link layer defined in ANSI/ASHRAE-135annex J.1.1.2Frame layout and data encodingEach BACnet frame consists of Network-protocol-data-unit (NPDU) and Application-protocol-data-unit (APDU). All data contained inside APDU is exchanged using BACnet tagging that allows encoding of BACnet object and property identifiers, single properties, arrays and lists.1.1.3Frame size and segmentationANSI/ASHRAE-135 requires each device to provide information of maximum accepted message length. It also defines list of standardized frame lengths that result from different data link layers. Each BACnet device object shall implementproperty of max-APDU-accepted that defines.M4M BACnet accepts messages of maximum length 480 octets.The standard allows sending messages above accepted length and defines segmentation rules that should be followed when transmitting segmented messages. Segmentation support is not required by standard for each device and canbe supported for receive, transmission or in both directions. Each BACnet device3/ 21

BACNET MA NUALobject is required to implement property that defines whether segmentation issupported and in which directions.M4M BACnet does not support segmentation, neither receive nor transmission.When length of response frame to received request exceeds capabilities of particular device, it shall send reject response with segmentation-not-supported error code. Then the request sent by client device shall be divided to several.4/2 1

BACNET MA NUAL2Supported features2.1ServicesANSI/ASHRAE-135 contains series of services that define how BACnet deviceswith different capabilities interact with each other and exchange informationover network.All services defined by BACnet standard have client-side and server-side implementation, called ‘initiate’ and ‘execute’ accordingly. Specific device profiles require implementation of particular services within ‘initiate’, ‘execute’ or both ofthem. Table 2 contains summary information of services implemented by M4MBACnet ho-IsI-AmXXServices divide into two categories: confirmed and unconfirmed. In case of confirmed services BACnet server devices are required to send any kind of response,accept, reject or error, while unconfirmed services does not have such requirement.2.1.1Data sharing servicesServices related to data sharing allow accessing majority of objects’ properties.BACnet standard defines requires each BACnet device to implement at least readproperty service, that allows reading single properties of single objects. Thestandard defines optional service read-property-multiple that allows readingmultiple properties of all objects, one property of multiple objects and multipleproperties of multiple objects. Write-property and write-property-multiple aredefined accordingly to write values to object’s properties.These services allow accessing both BACnet-defined and non-standard properties and objects, as long as they fulfill basic requirements that are applicable toall types of objects.2.1.2Dynamic device/object bindingServices of dynamic device binding and dynamic object binding allow client devices to discover BACnet devices that are available over BACnet network and resolve devices’ attributes.5 /2 1

BACNET MA NUALM4M BACnet implements all services required according to its BACnet profile, i.e. Who-Has, IHave, Who-Is, I-Am.When client-side device sends Who-Is or Who-Has request device that resolves as requestedone shall respond with initiating I-Am or I-Have message respectively. Request for discoveringdevice or object can be called with given object-identifier or object-name.2.1.3Device communication controlThis service allows disabling some functionalities communication of particular device for finite time or upon enabling. This service can be optionally password-protected.M4M BACnet supports disabling communication for finite time duration only without password.2.1.4Registering as foreign deviceM4M BACnet offers capability of registering as a foreign device when configured.BACnet devices require exchanging broadcast datagrams between each-other for full operation of the network. Due to security reasons broadcast messages are usually blocked by networking routers and gateways. Thus ANSI/ASHRAE-135 defines foreign device that is outsideof its physical BACnet network or logical subnet, and is capable of communicating with theremaining network. In order to do that BACnet network has to be equipped with BACnetBroadcast Management Device (BBMD) which is gateway between BACnet subnets and foreign devices.When configured, the device sends subscription request directly to the BBMD which storeslist of all registered foreign devices. Then BBMD is capable of forwarding all broadcast messages to foreign devices.The subscription of foreign device is time-finite with period defined by device itself and hasto be renewed before expiration in order to maintain uninterrupted communication with thedevice.M4M BACnet is capable of registering as a foreign device when proper configuration is provided. In order to do that BBMD mode shall be enabled and proper parameters for BBMD IPaddress, BBMD UDP port and BBMD TTL shall be set.6/ 21

BACNET MA NUAL3ObjectsBACnet standard defines object-oriented approach to access all information thatshall be exchanged over BACnet network. Each object is identified by its objectidentifier that consists of object-type and object instance. Object-identifier mustbe unique for each object within one BACnet device. BACnet standard definessome standard object types, vendors are allowed to create proprietary objecttypes with custom implementation as long as they meet basic requirements thatare applicable to objects of all types.Each object shall contain basic properties: object-identifier, object-type, objectname and property-list. For each of standard types the standard defines properties that are required or optional. Additionally some of the defined propertiesmight be required to be writable.Each of regular device shall contain exactly one instance of device object-type.Device object instance number and object-name shall be unique over BACnet network.M4M contains only objects of standard-defined types.3.1PropertiesBACnet has definition for available property types. Primitive data types includeCollection of properties can be presented as BACnet arrays or BACnet lists.BACnet array is one-indexed collection of elements having the same data typethat allows accessing elements of the array by reading each individual of themor accessing whole array. Reading array with given index equal to zero returnssize of the array. The array can be empty, i.e. its size can be equal to zero.BACnet list is one-based collection of elements having the same data type. BACnet list can be accessed using special-purpose service read-range.3.2List of BACnet objectsBACnet Objects supported by M4M BACnet meters are presented in tables below.7/ 21

BACnet array is one-indexed collection of elements having the same data type that allows accessing elements of the array by reading each individual of them or accessing whole array. Reading array with given index equal to zero returns size of the array. The array can be empty, i.e. its size can be equal to zero.
