Building automation and control systems (BACS) - Part 5: Data communication protocol (ISO 16484-5:2017)
The purpose of ISO 16484-5:2017 is to define data communication services and protocols for computer equipment used for monitoring and control of HVAC&R and other building systems and to define, in addition, an abstract, object-oriented representation of information communicated between such equipment, thereby facilitating the application and use of digital control technology in buildings.

Sistemi za avtomatizacijo in regulacijo stavb - 5. del: Protokol za izmenjavo podatkov (ISO 16484-5:2017)
EN-ISO 16484-5 nudi obsežen komplet sporočil za sporočanje šifriranih binarnih, analognih in alfanumeričnih podatkov med napravami, vključno z, a ne omejeno na: (a) binarne vhodne in izhodne vrednosti strojne opreme, (b) analogne vhodne in izhodne vrednosti strojne opreme, (c) binarne in analogne vrednosti programske opreme, (d) vrednosti besedilnih nizov, (e) informacije o razporedu, (f) informacije o alarmih in dogodkih, (g) datoteke in (h) nadzorno logiko. Ta protokol modelira vsako avtomatizacijo stavb in računalnik za regulacijo kot zbirko podatkovnih struktur, imenovanih »predmeti«, pri čemer njihove lastnosti predstavljajo različne vidike strojne in programske opreme ter delovanja naprave. Ti predmeti omogočajo identifikacijo in dostop do informacij, pri čemer ni zahtevano poznavanje podrobnosti notranje zasnove ali konfiguracije naprave.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national
standards bodies (ISO member bodies). The work of preparing International Standards is normally
carried out through ISO technical committees. Each member body interested in a subject for which a
technical committee has been established has the right to be represented on that committee.
International organizations, governmental and non‐governmental, in liaison with ISO, also take part in
the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. International Standards are drafted in accordance
with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
URL: www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 205, Building environment design.
This sixth edition cancels and replaces the fifth edition (ISO 16484‐5:2014), which has been technically
revised. See the detailed list of changes on pages 1 312 to 1 327.
