Introduction
The objective of this European Standard is to specify how sets of products from multiple manufacturers are
able to interoperate and be installed with or without the use of a special tool, in the most automatic manner.
By meeting this standard, future household appliances will be able to enjoy a significantly larger market.
Figure 1 shows what it takes to obtain interworking between household appliances:
• the Household Appliances Interworking standard. It is highly independent of the underlying protocol;
• a protocol for communication between devices in the home;
• a mapping scheme from the Household Appliances Interworking standard to each selected protocol.

EN 50523-1 defines the functionality required for appliances to ensure interoperability.
EN 50523-2 defines the data structures used to implement the interoperable functionality.
The Protocol Mapping specification is a document that describes the mapping of the defined interoperable
functionality in terms of a selected protocol that satisfies the requirements of EN 50523-1.
The Protocol specification defines a communication protocol suitable for communication between devices in
the home.

1 Scope
This European Standard focuses on interworking of household appliances and describes the necessary
control and monitoring. It defines a set of functions of household and similar electrical appliances which are
connected together and to other devices by a network in the home.
This European Standard does not deal with safety requirements.
2 Terms, definitions and abbreviations
2.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1.1
domain address
identification of a logical network on an open network such as power-line. Domain addresses are used in a
frame to insulate it from neighbouring networks
2.1.2
house address
see definition 2.1.1 for domain address
2.1.3
network address
identification of a device in a network
2.1.4
fixed addressing scheme
fixed addressing schemes are used when the network address is a unique identification assigned through an
agreement between manufacturers so that no two communicating devices have the same identification,
hence the same address
2.1.5
communication link
logical application link between two devices exchanging messages
2.1.6
installation
installation of all networked devices within a given home unit
2.1.7
configuration data
set of data including network protocol data (domain address and network address) and communication link
data
2.1.8
message
application message
2.1.9
local control
direct control of a device through its panel

remote control
control of device through a network
2.1.11
indoor remote control
control of device from a device connected to the home network
2.1.12
outdoor remote control
control of device from a device connected to a residential gateway itself connected to the home network
2.1.13
enable / disable remote control
authorisation to control a device through a network
2.1.14
Functional Block
logical grouping of device functions. Consists of one or more functions that belong together and that cannot
be separated across two devices. A Functional Block has a well-defined black-box behaviour

wet white goods
washing machine, dish washer, tumble dryer
2.1.16
hot white goods
oven, hobs, hood
2.1.17
cold white goods
refrigerator, freezer, refrigerator-freezer, winecabinet
2.1.18
air conditioner
this document refers to HVAC mobile devices which can be directly installed by the consumer
2.1.19
water heater
storage water heater (boiler) or instantaneous water heater
