Introduction
According to the OSI reference model, the Physical Layer consists of the medium, the cable, the connectors,
the transmission technology, etc. which refers to the hardware requirements. However, the focus of this
European Standard lies first and foremost on the description of the “communication medium”.
1 Scope
This European Standard defines the mandatory and optional requirements for the medium specific Physical
and Data Link Layer of Radio Frequency for HBES products and systems, a multi-application bus system
where the functions are decentralised, distributed and linked through a common communication process.
This European Standard is used as a product family standard. It is not intended to be used as a stand-alone
standard.
Data Link Layer interface and general definitions, which are medium independent, are given in
EN 50090-4-1.

5 Data Link Layer Type RF
5.1 Differences to existing (bi-directional) HBES protocol
5.1.1 Extended Group Address
The Extended Group Address (8 octets) in a HBES RF frame shall be the combination of the standard HBES
Group Address (2 octets) with the HBES Serial Number of the sender of the frame (6 octets). Every group
addressed HBES RF frame shall contain an Extended Group Address.
The consequence from 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 in account if the receiver knows the Extended Group Address
of the sender.
NOTE According to the HBES RF frame definition, these 8 octets are not transmitted consecutively.
The HBES RF frame shall contain the HBES 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 HBES 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 HBES 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”.
5.1.2 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 will 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.
---------------------- Page: 8 ----------------------
EN 50090-5-3:2006 - 8 -
• For Individual Addresses
All devices shall have the default Individual Address (05FFh).
5.1.3 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 HBES 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 HBES 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”.
5.1.4 RF Broadcast and RF System Broadcast
Broadcasts can be broadcasts within an installation or system broadcasts. Whether a broadcast is a system
broadcast shall be indicated by the AddrExtension
