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 an efficient implementation of synchronization, see 5.1.8.7.

Busch-Jaeger has informed IEC and ISO that they have the granted patent EP 0856954.

IEC and ISO draw attention to the fact that it is claimed that compliance with this document may involve the use of

a patent in case specific notch configurations are implemented.
Zumtobel has informed IEC and ISO that they have the granted patent DE 29701412.

ISO and IEC take no position concerning the evidence, validity and scope of these putative patent rights. The

holders of these putative patent rights have assured IEC and ISO that they are willing to negotiate free licences or

licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this

respect, the statements of the holders of these putative patent rights are registered with IEC and ISO. Information

connected by a medium to seven logical layers. This International Standard specifies

interconnection of entities used for home and building control via the medium powerline. It

specifies the medium dependent functions, that is the mains characteristics and the

transmission technology in terms of the Physical Layer and the Data Link Layer, according to

ISO/IEC 7498.

4 Conformance

A device conforming to this International Standard shall support the physical medium as

specified in clause 5 or clause 7, and it shall provide transmission capability as specified in

clause 6.
5 Requirements for HES Class 1, PL110
5.1 Physical Layer PL110
5.1.1 General

This clause describes the physical layer characteristics of the PL110 powerline signalling which

operates in the frequency band (95 to 125) kHz band as described in EN 50065-1 and which

has a nominal centre frequency of 110 kHz.
The main characteristics of PL110 physical layer are:
• a spread frequency shift keying signalling;
• asynchronous transmission of data packets;
• symbols globally synchronised to the mains frequency;
• half duplex bi-directional communication.

Electrical wiring in the building/home shall be in compliance with the current national

regulations. Powerline communication is described in EN 50065-1.

The electric power distribution network normally determines the physical topology of the

powerline network. The structure of this network may be single phase or three phase. The

rated voltage between one phase and neutral shall be 110 V and 230 V, respectively. PL110

signals are injected between phase and neutral.
General requirements for the physical layer type PL110 are given in Table 1.
Table 1 – General requirements for physical layer PL110
Characteristics Description
Medium Electrical power distribution network
Topology Installation dependant (e.g., linear, star, tree)
Bit rate 1 200 bit/s

105,6 kHz ± 0,1%
Frequency for logical 1
115,2 kHz ± 0,1%
Bit duration 833,3 µs

Equipment manufactured in accordance with class 116 according to EN 50065-1 will now meet the

requirements of Class 122 and may be marked Class 116 provided that its output complies with the

previous standard.

The logical structure of the physical layer PL110 entity is shown in Figure 1. Each PL110-

device includes one physical layer PL110 entity.
The PL110 entity shall consist of three blocks:
• connector;
• medium attachment unit (MAU);
• error correction.

5.1.2.1 Requirements for protection against electric shocks and connectors

The PL110 devices are connected to the mains installation network. The requirements for

protection against electric shocks for human beings (and animals) and connectors shall be

considered within the assembled device. They are not subject to the physical layer description.

These requirements are specified in the installation and equipment standards (safety

standards).
5.1.2.2 Powerline cables

The requirements for powerline cables are defined by the use as installation wires according to

national regulations. Normally, the type of cable, the connected loads and the topology of the

network is not known. In contrast to the theoretical values of typical cable characteristics, for

example as specified in IEC 60227-4 and IEC 60502-1, the impedance at one network access

point is determined more by the connected load than by the cabling.

Typical cables for fixed electrical installation are “thermoplastic-insulated and sheathed cable”,

“PC insulated flat cable, overall covering vulcanised rubber” or “sheathed metal-clad wiring

cable with PVC insulated cores sheet-zinc cover with additional PVC jacket”.

NOTE The use of shielded power cables and of cables with cross-sections greater than 35 mm can influence

PL110 signalling significantly!

5.1.3 Medium attachment unit (MAU)

The Medium Attachment Unit converts the frequency-coded signals into values representing

logical ones and zeroes and vice versa. In parallel, a power supply circuit may be connected to

the medium. Signal converter and power supply shall be independent from each other. The

power supply shall meet the requirements specified in Table 2.

5 V at 30 mA / 24 V at 1 mA

Transmitting 5 V at 30 mA / 24 V at 10 mA – 50 mA (dependent on
mode impedance)
Compliance is checked by measurement.
The power supply of the MAU may be internal or external.
5.1.3.1 Signal encoding

A signal of 105,6 kHz for a period of 833,3 µs shall correspond to a logical 0, a signal of

115,2 kHz for a period of 833,3 µs to a logical 1. See Figure 2.

Figure 2 – Signal encoding

These NRZ signals are superimposed on the AC voltage of the mains at 50 Hz and 60 Hz,

respectively. The maximum amplitude of the signal shall be limited to 122 dBμV, measured

according to EN 50065-1 by using an artificial mains network as specified in CISPR 16-1-1.
