24、 Standards Bodies and their Licensees to reproduce this document in full and including this copyright notice for the purposes of European standardisation. This technical specification covers the methods of mapping LONWORKS objects and services to BACnet objects and services and vice versa. The LONWO
25、RKS objects and services are defined in the standard EN 14908-1 “Control Network Protocol“ and the BACnet objects and services are defined in the standard EN ISO 16484-5 “Data Communication Protocol“. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the foll

CEN/TS 15231:20065 Introduction This Technical Specification specifies methods for the mapping of objects and services of the Control Network Protocol (CNP) , called LONWORKS (see EN 14908-1), and the Data communication protocol, called BACnet (se
28、e EN ISO 16484-5), for exchanging information between both systems. This Technical Specification has been prepared to provide mechanisms through which various vendors of building automation, control, and building-management systems, may exchange information in a standardised way between both LONWORK
29、S and BACnet communication systems. It specifies communication and internal-documentation requirements. This Technical Specification is for use by all involved in design, manufacture, engineering, installation, and commissioning activities; and has been made in response to the essential requirements
30、 of the Construction Products Directive. CEN/TS 15231:20066 1 Scope The LONWORKS communication system is widely used in building automation systems for field-level and application-level functions for residential and non-residential controls in lighting, sun protection, HVAC, energy management and se
31、curity applications. The BACnet communication system is also used in building automation systems for management-level and application-level functions. This Technical Specification defines the methods for combining BACnet networks with LONWORKS networks, and standardizes the interface between BACnet
32、and LONWORKS systems. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

34、For the purposes of this Technical Specification, the following terms and definitions apply. 3.1 Functional Profile FP A template that describes common units of functional behaviour. Functional profiles are also known as profiles, or FPs; which can be represented with a machine-readable functional-p
35、rofile template (FPT). Standard functional profiles are also known as LONMARK profiles. Each functional profile consists of a profile description and a specified set of network variables and configuration properties designed to perform a single function on a device. The network variables and configu
36、ration properties specified by the functional profile are called the functional-profile members. A functional profile specifies whether the implementation of each functional-profile member is mandatory or optional. A profile is uniquely identified by a program-ID template, scope, and functional-prof
37、ile number. 3.2 LONWORKS LONWORKS is the name of the whole technology used in LONWORKS. It describes the language, the transceivers and the Neuron Chips. The communication is typically based on network variables organized in functional profiles, which are standardized by LONMARK International. 3.3 L
38、ONMARK International LONMARK Internationals mission is to enable the easy integration of multi-vendor systems based on CNP networks. LONMARK INTERNATIONAL provides an open forum for member companies to work together on marketing and technical programs to promote the availability of open, interoperab
39、le control devices. 3.4 Network Variable NV A data item that a particular device application program expects to get from other devices on a network (an input network variable) or expects to make available to other devices on a network (an output network CEN/TS 15231:20067 variable). Examples are a t
40、emperature, switch value, and actuator position setting. Network variable data is typically stored in a devices volatile memory. 3.5 Node A node is a physical device in LONWORKS. Each LONWORKS device can be a member of maximum two domains. In each domain a maximum number of 255 subnets with 127 devi
41、ces each can be addressed. 3.6 Standard Configuration Property Type SCPT A configuration property type that has been standardized by LONMARK International. A SCPT is a standardized definition of the units, scaling, encoding, valid range, and meaning of the contents of configuration properties. 3.7 S
42、tandard Network Variable Type SNVT A network variable type that has been standardized by LONMARK International. 4 Object Structures 4.1 LONWORKS Objects (Functional Profile) 4.1.1 General The primary function of a LONMARK certified device must be implemented using one or more LONMARK profiles which
43、represent the application layer interface of the node. Functional Profiles are divided into mandatory and optional network variables, configuration properties, and a manufacturer defined section that is non-interoperable. They are based on six standard objects listed below. Table 1 Standard LONWORKS

46、ect in a LONWORKS node implements the application-level network management of the node as a whole. It contains two mandatory network variables (nvi_request and nvo_status). 4.1.3 Sensor Object Sensor objects are generic objects that can be used with any form of sensor for analog values such as tempe
47、rature, pressure, humidity or for digital values of switches or buttons. Via an output network variable nvoValue the data can be supplied directly to an actuator object or to a control loop located within a controller object. 4.1.4 Actuator Object The actuator objects are generic objects that may be
48、 used with any type of actuator, such as a valve, a light dimmer or a motor. They may be controlled by a remote controller object or directly by a sensor object. 4.1.5 Closed Loop Object A closed loop object gives a feedback to the sensor objects. It is used to synchronize sensor(s) and actuator(s).
49、 4.1.6 Controller Object A controller object is used for complex algorithms to control actuator(s). The controller object is not part of the prEN14908-5 standard. 4.1.7 Analog Output Object The analog output object is used to integrate devices that do not have the ability to interface directly to LONWORKS, but rather utilize an analog output conversion device that is LONMARK compliant. 4.1.8 Analog Input Object The analog input object is used to integrate devices that do not have the ability to interface directly to LONWORKS, but
