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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 16484-5 was prepared by the American Society of Heating, Refrigerating and Air-Conditioning Engineers
(ASHRAE) (as ANSI/ASHRAE 135-2008) and was adopted without modifications by Technical Committee
ISO/TC 205, Building environment design.
This third edition cancels and replaces the second edition (ISO 16484-5:2007), which has been technically
revised, as detailed in the enclosed ANSI/ASHRAE publication, pages 682 to 687. It also incorporates the
Amendment ISO 16484-5:2007/Amd1:2009.
ISO 16484 consists of the following parts, under the general title Building automation and control systems:
⎯ Part 1: Project specification and implementation
⎯ Part 2: Hardware
⎯ Part 3: Functions
⎯ Part 5: Data communication protocol
⎯ Part 6: Data communication conformance testing
Applications and project implementation are to form the subjects of future Parts 4 and 7.

ISO/FDIS 16484-5:2010(E) iv © ISO 2010 – All rights reserved 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. 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. ISO 16484-5 was prepared by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) (as ANSI/ASHRAE 135-2008) and was adopted without modifications by Technical Committee ISO/TC 205, Building environment design. This third edition cancels and replaces the second edition (ISO 16484-5:2007), which has been technically revised, as detailed in the enclosed ANSI/ASHRAE publication, pages 682 to 687. ISO 16484 consists of the following parts, under the general title Building automation and control systems: ⎯ Part 1: Project specification and implementation ⎯ Part 2: Hardware ⎯ Part 3: Functions ⎯ Part 5: Data communication protocol ⎯ Part 6: Data communication conformance testing Applications and project implementation are to form the subjects of future Parts 4 and 7.

INTERNATIONAL STANDARD ISO 16484-5:2010(E) Building automation and control systems — Part 5: Data communication protocol 1 Scope This part of ISO 16484 defines data communication services and protocols for computer equipment used for monitoring and control of heating, ventilation, air-conditioning and refrigeration (HVAC&R) and other building systems. It defines, 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. The scope and field of application are furthermore detailed in Clause 2 of the enclosed ANSI/ASHRAE publication. 2 Requirements Requirements are the technical recommendations made in the following publication (reproduced on the following pages), which is adopted as an International Standard: ANSI/ASHRAE 135-2008, A Data Communication Protocol for Building Automation and Control Networks The text on the back of the title page of the ANSI/ASHRAE standard and the policy statement on the last page are not relevant for the purposes of international standardization.
