22、alta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom EN ISO 16484-2:2004 (E) 4 Introduction This series of standards is intended for design of new buildings and retrofit of existing buildings for an acceptable indoor environment, practical en
23、ergy conservation and efficiency. The application of this series of standards for BACS is envisaged as follows: - the environmental design for all building types requires complex methods for automation and control. The functional integration of services other than HVAC e.g. lighting and electric pow
24、er distribution control, security control, transportation, maintenance management or facilities management is a general task for all parties employed to develop an integrated multi-application system. This integration allows the user to take advantage of synergies between the different applications.
25、 This standard will give guidance to architects, consultants and contractors as well as to users on how to share such resources, - the innovation cycles between devices, systems and networks vary. To make it possible to add and to change existing devices, and extend the building automation and contr
26、ol network, several interfaces both proprietary and standardized are defined between the BACS network and the other systems. A manufacturer can design a product, both to meet his specific marketing objectives and to give the option to integrate that special device into a multi-application BACS. Inte
27、rfaces are also defined in appropriate parts of this standard along with the necessary communications protocol and conformance test required to support the inter-working of devices, - a manufacturer, a systems house, or an electrical or mechanical contractor can assemble an implementation of a build
28、ing automation and control system, - the application of this standard is not to standardize the hardware and software design or the architecture of a System, but to define the process for the creation of project specifications, where functionality and the quality of the solution are clearly defined.
29、 The purpose of this series of standards is intended for use by those involved in the design, manufacture, engineering, installation, commissioning, operational maintenance and training of BACS when contracted, i.e.: as a guide to the terminology of the building automation and control trade. Unambig
30、uous terminology is required for a complete and accurate conveyance of the intent and details of this standard; in product development, to avoid unnecessary duplication of function or terminology, but should not place a restraint on the evolution of new products, systems or applications; as a basis
31、for interfacing products and systems. In order to interoperate, the elements of a BACS require a unified data communication protocol and information model; as a basis for drawing up a project specification for the procurement of building automation and control products for systems suppliers and cust
32、omers; as a code of practice for expertly commissioning prior to handover of a system; by educational establishments wishing to train people in the field of building automation and control systems. This entire series of BACS standards consists of the following contents: Part 1: Overview and definiti
33、ons (in preparation) Part 1 of this standard describes the objectives and interrelationships of all parts of this standard. It provides an overview and detailed information about the structure of the related series of standards for the BACS industry. This part of the standard provides also the vocab
34、ulary with terms and definitions for the understanding of the entire series of this standard and it contains a translation of the main terms in English, French, Russian, and German in an informative annex. EN ISO 16484-2:2004 (E) 5 This ongoing work is coordinated at expert level with standards work
35、 from ISO/TC 205 WG 3 and CEN/TC 247/ WG 3, WG 4, WG 5 and WG 6. Part 2: Hardware (refer to the scope of this part) Part 3: Functions Part 3 of this standard specifies the requirements for the overall functionality and engineering services to achieve building automation and control systems. It defin
36、es terms, which shall be used for specifications and it gives guidelines for the functional documentation of project/application specific systems. It provides a template for documentation of plant/application specific functions, called BACS function list in annex A. The informative function block ex
37、amples explain a method to display the referenced functions in system documentation; they do not standardize the method for programming functions and applications. This Part 3 of the standard covers the following: Requirements and definitions regarding BACS and application software, generic function
38、s for plant/project specific applications and engineering functions for building controls and operations. It provides communication functions for the integration of other dedicated special system processes. The functional requirements in this part of the standard are subdivided as follows: System ma
39、nagement and application software: describes the requirements for plant independent system and human system interface programs related to a project, including the operating system. This standard does not dedicate the following system functionality to any particular hardware, e.g.: system diagnostics
40、, watchdog, redundancy, time keeping, access control, log lists; point identification, event message handling, print control; database, statistics, data archiving, remote access; system communications. Human system interface (HSI), point information presentation, graphics, alarms, time scheduling En
41、gineering process and tool software: describes the requirements for configuring of the hardware and control strategies, the system management and the commissioning process. BACS application processing programs and plant/application specific functions: describes the requirements for plant, applicatio
42、n and / or project specific functions and a method for the documentation of a project. The functions are subdivided into the following types: input and output functions; processing functions; management functions and required communications; operator functions. Part 3 defines a method for creating t
43、he procurement specifications containing all essential elements required for the operational functioning of a BACS. The successful installation and operation of a BACS requires that its procurement be based on a complete specification with accurately defined functions. The standard provides a templa
44、te called the BACS function list that can be found in annex A (normative). Its purpose is to determine and document the options for plant / application specific functionality. Further EN ISO 16484-2:2004 (E) 6 explanations can be given in form of plant/control descriptions, control flow chart diagra
45、ms, and plant/control schematics. Examples are given in annex B (informative). The exact specifications will be project-specific. Information about the standardized functions is given in the form of informative examples as function-blocks, textual, and graphical descriptions in 5.5. It is recognized
46、, that functions can be described and implemented in many different ways, depending on: climatic differences; cultural and regional differences; national regulations. Part 4: Applications Part 4 of this standard specifies the requirements for specific communicating applications/devices, e.g. for gen
47、eral room automation and for sophisticated optimization of controls for heating, fan coil and induction units, CAV, VAV and radiant cooling. This work will be coordinated at expert level with standards work from ISO/TC 205 WG 3 and CEN/TC 247. Part 5: Data Communication Protocol Part 5 of this stand
48、ard specifies data communication services and objects for computer equipment and controllers used for monitoring and control of HVAC output positioning/set-point: analog output object; binary input counting; input state: binary input object, multi-state input; output switching: binary output object, multi-state output; values: analog value, binary value, multi-state value, accumulated value, averaging object, trend log object; text string; schedule information; alarm and event information; files; and contro
