4 Requirements for HBES Class 1, power line PL110
4.1 Physical layer PL110
4.1.1 General
This clause describes the physical layer characteristics of the PL110 power line signalling which operates
in the frequency band 95-125kHz band as described in EN 50065-1 and having a nominal centre
frequency of 110 kHz.
The main characteristics of the PL110 physical layer are:
• a spread frequency shift keying signalling;
• asynchronous transmission of data packets;
• symbols globally synchronized to the mains frequency;
• half duplex bi-directional communication.
Electrical wiring in the building/home shall be in compliance with the current national regulations. Power
line communication is described in EN 50065-1 (general requirements, frequency allocation and
electromagnetic disturbances).
The electric power distribution network normally determines the physical topology of the power line
network. The structure of this network may be 1- or 3-phase. The rated voltage between one phase and
the neutral shall be 230 V. PL110 signals are injected between phase and neutral.
General requirements for the physical layer type PL110 are given in Table 1.

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

4.1.2.1 Requirements for protection against electrical shocks and connectors
The PL110 devices are connected to the 230 V installation network. The requirements for protection
against electrical shocks for human beings (and animals) and connectors shall be considered within the
complete device and are not subject to the physical layer description.
These requirements are fixed in the installation and equipment standards (safety standards).
4.1.2.2 Power line cables
The requirements for power line 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. Some widespread cables are listed in Table 2. In contrast to the theoretical values, the
impedance at one network access point is determined more by the load than by the cabling.

---------------------- Page: 9 ----------------------

SIST EN 50090-5-1:2005
- 9 - EN 50090-5-1:2005
Typical cables for fixed electrical installation are “thermoplastic-insulated and sheathed cable“, “PVC-
insulated flat cable, overall covering vulcanized rubber“ or “sheathed metal-clad wiring cable with PVC-
insulated cores sheet-zinc cover with additional PVC-jacket” .

Inductance 1,2 µH/m to 1,5 µH/m

NOTE The use of shielded cables and cables with cross sections greater than 35 mm can influence PL110 signalling significantly!
4.1.3 Medium attachment unit (MAU)
The medium attachment unit converts the frequency-coded signals into values representing logical ones
and zeros 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
following requirements:

Receiving 5 V at 30 mA / 24 V at 1 mA

Transmitting 5 V at 30 mA / 24 V at 10 mA - 50 mA

Compliance is checked by measurement.
The power supply of the MAU may be internal or external.

4.1.3.1 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.

logical "0" logical "1"

Figure 2 - Signal encoding
These NRZ-signals are superimposed on the 230 V/50 Hz mains AC-voltage. The maximum amplitude of
the signal shall be limited to 122 dBµV, measured with EN 5506-1-2 artificial mains network according
EN 50065-1. The sensitivity of the receiver shall be better than 60 dBµV.
For lowest disturbances, the change between adjacent symbols shall be phase continuous.
Compliance is checked by measurement.
4.1.3.2 Overlapping of logical "0" or "1"
Overlapping of logical "0" or "1"-symbols, e.g. the simultaneous transmission of equal information at the
same time from several MAU's (e.g. common ACK), results in fade-in / fade-out effects. Due to slight
frequency deviations between several MAU's the signal fades periodically with the difference of the MAU-
frequencies. In PL110 power line communication this case can be avoided by setting a unique group
response flag to each assigned Group Address.
4.1.3.3 Overlapping of logical "0" and "1"
Overlapping of logical "0" and "1"-symbols, e.g. the simultaneous transmission of different information at
the same time from several MAU's, results in a collision. While there is no indication of collision for any
MAU, the probability of this state is minimized by special bus access mechanism.

To limit the influence of connected MAU's on the characteristic of the power line bus the impedance in

4.1.6 Surge protection
The electrical installation may or may not be provided with external surge protection. Where external SPD
is provided it shall comply with type 1 (for primary protection) or type 2 (for secondary protection)
according to EN 61643-11.
4.1.7 Services at the data link layer / physical layer interface
Two services Ph_Data.req (p_class, p_data) and Ph_Data.ind (p_class, p_data) shall be implemented at
the data link / physical layer interface:
