Building automation and control systems (BACS) — Part 6: Data communication conformance testing

This standard provides a comprehensive set of procedures for verifying the correct implementation of each capability claimed on a BACnet PICS including: (a) support of each claimed BACnet service, either as an initiator, executor, or both, (b) support of each claimed BACnet object-type, including both required properties and each claimed optional property, (c) support of the BACnet network layer protocol, (d) support of each claimed data link option, and (e) support of all claimed special functionality.

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.

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

This document was prepared by Technical Committee ISO/TC 205, Building environmental design, in

collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC

247, Building Automation, Controls and Building Management, in accordance with the Agreement on

technical cooperation between ISO and CEN (Vienna Agreement).

This fourth edition cancels and replaces the third edition (ISO 16484-6:2014), which has been technically

revised See the detailed list of changes in pages 724 to 728.

4. ELECTRONIC PICS FILE FORMAT
1. PURPOSE

To define a standard method for verifying that an implementation of the BACnet protocol provides each capability claimed

in its Protocol Implementation Conformance Statement (PICS) in conformance with the BACnet standard.

2. SCOPE

This standard provides a comprehensive set of procedures for verifying the correct implementation of each capability

claimed on a BACnet PICS including:

(a) support of each claimed BACnet service, either as an initiator, executor, or both,

(b) support of each claimed BACnet object-type, including both required properties and each claimed optional

property,
(c) support of the BACnet network layer protocol,
(d) support of each claimed data link option, and
(e) support of all claimed special functionality.
3. DEFINITIONS
All definitions from ANSI/ASHRAE Standard 135-2016 also apply to this addendum.
3.1 local network: the network to which a BACnet device is directly connected.

3.2 remote network: a network that is accessible from a BACnet device only by passing through one or more routers.

3.3 test database: a database of BACnet functionality and objects created by reading the contents of an EPICS.

3.4 Abbreviations and Acronyms Used in the Standard
BNF Backus-Naur Form syntax
EPICS electronic protocol implementation conformance statement
IUT implementation under test
TCSL testing and conformance scripting language
TD testing device
TPI text protocol information
4. ELECTRONIC PICS FILE FORMAT

An electronic protocol implementation conformance statement (EPICS) file contains a BACnet protocol implementation

conformance statement expressed in a standardized text form. EPICS files are machine and human readable representations

of the implementation of BACnet objects and services within a given device. EPICS files shall use the extension ".TPI"

(text protocol information) and contain normal editable text lines consisting of text character codes ending in carriage

return/linefeed pairs (X'0D', X'0A').

EPICS files are used by software testing tools to conduct and interpret the results of tests defined in this standard. An

EPICS file shall accompany any device tested according to the procedures of this standard.

4.1 Character Encoding

BACnet provides for a variety of possible character encodings. The character encodings in BACnet fall into three groups:

octet streams, double octet streams and quad octet streams. Octet streams represent characters as single octet values. In

some cases, such as Microsoft DBCS and JIS C 6226, certain octet values signal that the second octet which follows should

be viewed along with the leading octet as a single value, thus extending the range to greater than 256 possible characters.

In contrast, double octet streams view pairs of octets as representing single characters. The ISO 10646 UCS-2 encoding is

an example. The first or leading octet of the pair is the most significant part of the value. Quad octet streams, such as ISO

10646 UCS-4, treat tuples of four octets at a time as single characters with the first or leadi

...
