FOREWORD
1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) form
the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards. Their preparation is entrusted to technical
committees; any ISO and IEC member body interested in the subject dealt with may participate in this
preparatory work. International governmental and non-governmental organizations liaising with ISO and IEC
also participate in this preparation.
2) In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to
national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the
national bodies casting a vote.
3) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC and ISO member bodies.
4) IEC, ISO and ISO/IEC Publications have the form of recommendations for international use and are accepted
by IEC and ISO member bodies in that sense. While all reasonable efforts are made to ensure that the
technical content of IEC, ISO and ISO/IEC Publications is accurate, IEC or ISO cannot be held responsible for
the way in which they are used or for any misinterpretation by any end user.
5) In order to promote international uniformity, IEC and ISO member bodies undertake to apply IEC, ISO and
ISO/IEC Publications transparently to the maximum extent possible in their national and regional publications.
Any divergence between any ISO/IEC Publication and the corresponding national or regional publication should
be clearly indicated in the latter.
6) ISO and IEC provide no marking procedure to indicate their approval and cannot be rendered responsible for
any equipment declared to be in conformity with an ISO/IEC Publication.
7) All users should ensure that they have the latest edition of this publication.
8) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual
experts and members of their technical committees and IEC or ISO member bodies for any personal injury,
property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including
legal fees) and expenses arising out of the publication of, use of, or reliance upon, this ISO/IEC publication or
any other IEC, ISO or ISO/IEC publications.
9) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
IEC and ISO draw attention to the fact that it is claimed that compliance with this document may involve the use of
a patent concerning 6.6.2.

INTRODUCTION
The Reference model for Open System Interconnection (OSI), specified in ISO/IEC 7498,
assigns the functions that are needed for communications between two entities that are
connected by medium to seven logical layers. This International Standard specifies
interconnection of entities used for home and building control via the medium radio frequency.
According to the OSI reference model, the Physical Layer consists of the medium, the cable,
the connectors, the transmission technology, etc., which are hardware requirements. However,
the focus of this International Standard lies first and foremost on the description of the
“communication medium”.
Currently, ISO/IEC 14543, Information technology – Home Electronic System (HES)
architecture, consists of the following parts:
Part 2-1: Introduction and device modularity
Part 3-1: Communication layers – Application layer for network based control of HES Class 1
Part 3-2: Communication layers – Transport, network and general parts of data link layer for
network based control of HES Class 1
Part 3-3: User process for network based control of HES Class 1
Part 3-4: System management – Management procedures for network based control of HES

6 Data Link Layer Type RF
6.1 Differences from existing (bi-directional) HES protocol
6.1.1 Extended Group Address
The Extended Group Address (8 octets) in a HES RF frame shall be the combination of the
standard HES Group Address (2 octets) with the HES Serial Number of the sender of the frame
(6 octets). Every group addressed HES RF frame shall contain an Extended Group Address.
The consequence of this is that groups consist of one sender and n receivers, hence form a
1-to-n relationship. If several senders control a group of actuators, each of these actuators
shall listen to the sending addresses of all senders.
The receiver shall only take a received frame into account if the receiver knows the Extended
Group Address of the sender.
NOTE According to the HES RF frame definition, these 8 octets are not transmitted consecutively.
The HES RF frame shall contain the HES Serial Number of the sender for the following
communication modes:
• point-to-multipoint, connectionless (multicast) and
• point-to-system, connectionless (system broadcast).
This shall be indicated by the value 0 of the field AddrExtensionType in the second block of the
HES RF frame. Multicast frames received with the wrong value of the AddrExtensionType shall
be discarded by the receiving Data Link Layer instance.
For other communication modes, the HES RF Domain Address shall be used.
In any frame in system broadcast communication mode the Destination Address shall be 0000h
and the Address Type shall be “group”.

---------------------- Page: 10 ----------------------
– 10 – 14543-3-7 © ISO/IEC:2007(E)
6.1.2 Predefined Extended Group Addresses for transmit-only devices
Transmit only devices shall use Extended Group Addresses. As transmit-only devices only
have sending Datapoints (only one Group Address per Datapoint), all addresses can and shall
be factory set.
• For Group Addresses:
For all unidirectional sensors, Datapoint 1 shall have Group Address = 0001h, Datapoint 2 shall
have Group Address = 0002h, Datapoint N shall have Group Address = N, with as result on the bus
Extended Group Address (Serial Number of sensor, 0001h) , (Serial Number of sensor, 0002h)
and (Serial Number of sensor, N). These Group Addresses shall be unique for each sender.
• For Individual Addresses:
All devices shall have the default Individual Address (05FFh).
6.1.3 RF Domain Address
The RF Domain Address shall be a 6 octet number. The RF Domain Address in an RF
installation shall always be identical to the HES Serial Number of one of the devices in the
installation. This shall guarantee that the RF Domain Address is a unique number.
The RF frame shall contain the RF Domain Address for the following communication modes:
• point-to-point, connectionless,
• point-to-point, connection-oriented and
• point-to-all-points, connectionless (broadcast).
This shall be indicated by the value 1 of the field AddrExtensionType in the second block of the
RF frame. Point-to-point connectionless and point-to-point connection-oriented frames received
with the wrong value of the AddrExtensionType shall be discarded by the receiving Data Link
Layer instance.
For other communication modes, the HES Serial Number shall be used.
In any frame in broadcast communication mode the Destination Address shall be 0000h and
the Address Type shall be “group”.
6.1.4 RF Broadcast and RF System Broadcast
RF Broadcasts may be propagated beyond a given RF installation (= domain)can be
broadcasts within an installation or system broadcasts. In this case broadcast becomes a
system broadcast which shall be indicated by the AddrExtensionType field in the second block
of the RF frame.
0: system broadcast (shall not be restricted to the RF installation = domain; the frame shall
contain the Serial Number of the sender).
1: broadcast (shall be restricted to the installation = domain; the frame shall contain the
Domain Address).
6.2 Data Link Layer Frame
6.2.1 General
This clause specifies the frame format of the HES-RF system.
6.2.2 Structure
The frame format builds on the FT3 Data Link Layer (see IEC 60870-5). The frame shall
consist of a preamble (Physical Layer), several data blocks, each followed by 2 octets CRC,
and a postamble (Physical Layer).

---------------------- Page: 11 ----------------------
14543-3-7 © ISO/IEC:2007(E) – 11 –
The first data block shall have a fixed length of 10 data octets. The following blocks shall
contain 16 data octets, except the last block, which may contain less than 16 octets (the
remainder).
The HES RF-Ctrl octet in the second data block contains the 4 bits “frame format”.

6.2.3 Bit and octet order
Data shall be transmitted most significant bit (msb) first.
For data fields consisting of multiple octets (e.g., HES Serial Number/Domain Address and
Device Addresses) the most significant octet (MSB) shall be transmitted first.

• SN/DoA: Serial Number or Domain Address of the sender. The field AddrExtensionType in
the L/NPCI in the second block shall indicate whether this field contains the HES Serial
Number or the Domain Address.
• CRC: according to IEC 60870-5-1
For information: The CRC according to FT3 of IEC 60870-5-1 uses
16 13 12 11 10 8 6 5 2 0
2 +2 +2 +2 +2 +2 +2 +2 +2 +2
as a generator polynomial. It starts with zero and treats the data msb first. The CRC result is
complemented. The MSB of the 16-Bit CRC is transmitted first.
Example: the sequence 01 02 03 04 05 06 07 08 has the CRC FCBC.

6.3 Medium access
Medium access control serves to prevent collisions on the RF medium. Medium access cannot
be completely controlled on RF for two reasons:
• Unidirectional senders access the medium at unpredictable times.
• Non-HES RF devices access the medium at unpredictable times.
Bidirectional devices are able to sense whether the medium is free before they transmit. The
interframe time is the time interval a bidirectional device waits for a free medium (regardless of
whether it was addressed by the previous frame). If no preamble is detected during this
interframe time the device may start sending.
When a frame is received while the Physical Layer receives a request to send, the interframe
time shall start after the frame reception is completed, i.e., after the
...
